Is your house standing on an earthquake faultline?

Go to Links & Maps

Remember Haiti. Just recently, Negros Oriental. Will the Marikina
Valley Faultline move next?

While Phivolcs estimates the return period of this quake at about
200 to 400 years, no large earthquake has occured in the West
Valley Fault since the 1700s. With the last significant event recorded
in 1658, or about 350+ years ago, scientists say the faultline moving
now is long overdue.

Below are three versions of the maps I assembled which reveal the
more populated sections of the WEST FAULT of the Marikina Valley
Faultline System (MVFS).

To view these maps, pls. click on each image (while pressing the Ctrl
button) to open in separate browser tabs. Again click to ZOOM IN
close-up to make the street names readable (you may wait five
seconds for the image to focus). Then SCROLL LEFT and RIGHT or
UP and DOWN to navigate through the path of faultlines.

PHIVOLCS’ WEST FAULT__MAIN METRO
My one long stitched-up version of the many faultline maps of Phivolcs which you can verify from its official site.

GOOGLE MAP’S WEST FAULT__MAIN METRO
< detailed, updated, and revealing >
Another one long map I painstakingly assembled from the fault trace located by nababaha.com on Google Map.

PROOF OF ACCURACY
While our only source of the MVFS are the maps from Phivolcs, this trace overlay of the faultline from my assembled Google Maps approximates the faultline of Phivolcs with a high level of accuracy.

As quick preview for these maps (chances are the following list is
not complete –please let me know what communities and subdivisions
that i missed out), the WEST FAULT all along has been sitting right
under the noses of  residents of the following barangays and subdivisions:

PEMBO
……………COMEMBO
………………………………EAST REMBO

BAGONG ILOG
…………… KAWILIHAN
………………………………ST. JOSEPH HEIGHTS

CALUMPANG HILL
……………VALLE VERDE
……………………………..GREEN MEADOWS

WHITE PLAINS
………………ST. IGNATIUS
………………………………INDUSTRIAL VALLEY

DON JUAN
……………CINCO HERMANOS
………………………………LOYOLA GRAND VILLAS

LOYOLA SUBD.
……………BARANGKA
………………………………CAPITOL HOMES

SUNNYSIDE
……………DOÑA ANA
………………………………FILINVEST HOME II

BAGONG SILANGAN


Continuing south-bound…

The WEST FAULT continues in the direction of south-west using the
leftmost side of the “main metro” maps above as take-off point.  To
explain, the “south-bound” maps below end where the “main metro”
maps above begin.

With this in mind, the following maps can be viewed starting from the
right going left:

Coming from Libis, Quezon City and continuing in the general
direction of Bicutan, Taguig, then for a short distance running parallel
to Manuel L. Quezon Rd and SLEX, the faultline becomes hardly
straight and visible and breaks into scratch-like marks to affect many
areas in Muntinlupa, Biñan, and Carmona. It tapers off with a series
of forks or what look like bird tracks, if you will. With silent tenacity,
the WEST FAULT cuts a wide forbidding path through the following
communities while their residents remain utterly clueless:

(communities identified from left to right of these maps)
SILCAS VILLAGE
……………………………BMS VILLAGE
…………………………………………………JUANA COMPLEX

ROSARIO COMPLEX
……………………CALINDOLA VILLAGE
…………………………………………………SAMPAGUITA VILLAGE

ADELINA COMPLEX
…………………………HOLIDAY HOMES
…………………………………………………NENITA HOMES

VILLA CAROLINA
……………………SUSANA HEIGHTS
…………………………………………………PARK HOMES

LADEJO SUBD.
…………………………TUNASAN
…………………………………………………LODORA SUBD.

STO. NINO VILLAGE
…………………… POBLACION (MUNTINLUPA)
…………………………………………………JPA SUBD.

COUNTRY HOME
……………………BRUGER SUBD.
……………………………………………LAKEVIEW HOMES

FREEDOM HILLS
…………………………L&B SUBD.
…………………………………………NEW ALABANG HILLS

LIBERTY HOMES
…………………………POSADAS VILLAGE
…………………………………………………SIGNAL VILLAGE

FORT BONIFACIO
……………………………………PEMBO
…………………………………………………………COMEMBO

EAST REMBO


C
utting through the mountain…

From the Cavite-Laguna area where the WEST FAULT is last
located, we swing to the other side of the “main metro” maps where
the other end of the WEST FAULT touches Filinvest Homes II and
Bagong Silangan in Quezon City.

Again, to re-orient the reader, the maps below begin where our first
posted maps labeled “main metro” end:

GOOGLE MAP’S WEST-EAST FAULTS__MOUNTAIN-SIDE PARALLEL FAULTLINES
<Note: affected areas in San Mateo and Montalban also shown>

This other end of the WEST FAULT seems to halt in the far reaches
of Quezon City near Montalban which, I believe, are already the
foothills of a mountain. Though at a glance the area seems sparsely
populated, residents of the following barangays and subdivisions are
nonetheless warned:

SUNNYSIDE SUBD.
……………………DONA ANA SUBD.
……………………………………FILINVEST HOMES II

BAGONG SILANGAN
………………………PAGATAS
………………………………………CHRISTINE VILLAGE

AMITHY VILLAGE
………………………AMITYVILLE
……………………………………………HACIENDA REMEDIOS


Parallel faultlines overlap…

An important note: these few communities (also those others less
identifiable and not named here) appear to lie on a special area not
shared by the other residential areas listed in this blog. To wit,
shown on the Google Map that is the last map above, bounding
these communities on their north is the WEST FAULT that can
be  seen running neatly from left to right, then suddenly splitting
three ways like a fork with each fault heading off to God knows
where that is not covered by the maps.

Now hedging these communities in with the WEST FAULT above
is  the EAST FAULT below them that tapers off from the mountains
where this shorter faultline begins. At this point, EAST FAULT meets
WEST FAULT as they lie parallel to one other. What this means to
these communities surrounded by these two major faultlines, I can
only guess.

Lastly, along the EAST FAULT which lies mostly on rough, wild
country is GLORIA VISTA SUBDIVISION in San Mateo, and those
near this faultline that should be careful of landslides are Modesta
Village, Mary Hills Subdivision, and Life Home Subdivision.

◊ ◊ ◊


There. The cat’s out of the bag….

For those these revelations have been life-changing, it may do well
to rather think of it as life-saving. From first reactions of shock and
confusion, maybe also denial, realization should set in: that
life will go
on and pass us by no matter what.  So people will choose to MOVE
FORWARD.

Let us realize the faultline has been there for tens of thousands of
years
–maybe millions of years and will still be there even if we
humans become
extinct. So let’s get a grip of ourselves.  Let us
look at the problem in the eye and
deal with our situation.

Before there can be any answers, we should be asking the right
questions first

      I am not a geologist. But gut feel tells me whatever forces created the VALLEY in the west and east valley fault lines, it can make a repeat of the ground dropping by an x number of meters. By the way, other than the east and west valley fault lines, there are other “UNTOLD CRACKS ON THE GROUND” near the area that once upon a time may have caused the wawa dam legend of Bernardo Carpio. Pls. see my post, ANTIPOLO: HIDDEN IN PLAIN SIGHT and pray to God for insight.

    Great day Mr. Tulisanes,

    Im just surprised and same time curious on the changes made from the 2010 hazard map to the latest 2015 map. Wondering what geographical technology that phivolcs had been using to detect faults which are several kilometers deep from the surface?? It seems that the accuracy of finding these faults is almost the same as to when will the movements occur. I hope its not much like of predicting weather conditions made by Pag asa wherein typhoon movements or tracts are changing. So in 3 to 5 years from now, the assumption of Ayala ave all the way to SM Mall of Asia might as well be sitting directly under a fault may not be impossible.

      i understand we puny humans in the grand scheme of things cannot really have the gall to say WE KNOW BECAUSE WE ARE IN CONTROL. i guess close enough is good enough after realizing pinpointing fault lines cannot be an exact science. but i hope phivolcs reconsider its 5 meter buffer zone and maybe increase it to 15 meters instead, considering the always lingering thought of change the fault trace once who can stop them from changing it again.

        Thanks for replying Mr. Tulisanes. Your focus and patience in this important natural earth structure specifically on the west, east and southern areas of the NCR where majority of the inhabitants in the Philippines are present. With these scientific research and discoveries of the earth structure in connivance with Phivolcs creates serious awareness on the citizens of NCR and nearby provinces on the catasthropic danger of the East and West Valley faults may bring when it moves. Specially at present where this phenomenom are always in the news. Maybe you, Phivolcs and other experts can safely say that the fault networks are ONLY concentrated in the east, west and southern areas of NCR?

      Sampaloc, Manila is far from the fault line. but if the structure above your head is very old or was not designed by a licensed architect and licensed structural or civil engineer, then you are nonetheless VERY MUCH affected as the structural integrity of the house or building may be weak, and the roof and walls can collapse.

      “The West Valley Fault is known to generate big quakes every 400 to 600 years, he explained. The last major quake happened 357 years ago in 1658, meaning another one can happen as soon as 43 years from now.”

      i can’t find Bougainvillae/Bonggavilla St. among the street names in the satellite view of industrial valley. but it seems to be in an area where names of flowers dominate and lie alongside one another, like waling-waling, yellowbell, marigold, camella and petunia streets. as far as i can tell, the faultline crosses none of these! rather the zodiac streets with the names libra, capricorn, virgo, scorpio, cancer, gemini, aquarius and taurus are targeted victims of the west valley fault.

    I would like to know how much will we be affected if we experience a 7.2 magnitude earthquake? I live in Brgy Fortune, Marikina and its quite near the fault line. What should we expect?

    Is there a safe distance from the fault line? I’ve read that it would have more effect on buildings. But what about for houses? Is there a safe distance where the effects would be minimal?

      i figured the faultline, specially the west valley fault, was determined obviously by some sophisticated, state-of-the-art technology that we just have to have faith in. from what ground impressions of topography through patterns seen and directions made out that a graphic representation was created in the form of a red line. in other words, there are areas that have long solid red lines which tell the faultline that runs there is unmistakable –beyond shadow of a doubt! however, there are areas that appear to hide the faultline underneath (no obvious cracks at a glance, so to speak), and traces could be seen here and there, and the repetition of the “here and there” are what creates these dash lines. but make no mistake, these dash lines can mean the earth underneath can rip apart should a quake strong enough like a 7.2 magnitude hit!

        Tulisanes, it’s good to inform people — so, good job doing that. But it’s not so good to inform them of only half the truth. The whole truth is, it doesn’t matter where you are relative to the faultlines, as this MMEIRS study suggests. The truth is, if your home or place of work is within 50 km (or even father) from the faultlines, and they were not properly engineered to the latest standard* — either you didn’t get an engineer to do design it properly, or you got an engineer but he didn’t design it properly — your life and property are at risk. (* If your building/house/structure was designed and built after 2001, when the latest modern structural code that accounts for these faultlines was published, maybe you will be safe. Note also that many people die because of non-structural falling hazards such as heavy furnitures, ceilings, broken glass, etc. You don’t need to be on the faultline to experience that.)

        if how i stand at this point in time is judged as revealing half the truth, then it is but a snapshot of a dynamic and evolving truth that had triumphed from being kept in the dark like the many who visit this blog and are NOW being awakened from their cradle of ignorance. simply put, people are being given a chance to avoid making the I-DON’T-KNOW-BECAUSE-NOBODY-TOLD-ME lame excuse! information like what you bring can contribute to and enrich that truth and help in every personal and individual decision-making that can save lives and, perhaps, lower the estimated death count of 37,000 as projected in a 2013 AusAid Hazard Maps Study. “personal and individual” because each one should be given a chance to decide for himself and his family and not by some others who wish to play god over the destiny of the majority, no matter how good-meaning their intentions may be.

        what i present in this blog are not new. the information has been there all along. ineptness or inefficiency to deliver and communicate this life-saving information can be forgivable. but to deliberately withhold information is deadly sin. my role is to generate awareness, and with a fair amount of responsibility at that.

        by the way, that “half the truth” you find missing and try to fill in with your short but concise comment (thank you for providing emphasis on the subject) has already been addressed comprehensively by an expert in my special post here. generally, whenever asked, i always advise to consult a structural engineer when in doubt if a house or building can withstand an earthquake.

        i must disagree, however, with your last remark that seem to belittle the danger of being housed directly atop a faultline. it must be remembered that the july 16, 1990 luzon killer earthquake “produced a 125-kilometer ground rupture that stretched from dingalan, aurora to kayapa, nueva ecija, movements along the philippine fault and digdig fault.” getting a cue from that, it means that if your house is standing directly atop the marikina valley faultline, no matter how strong and reinforced its structures may be, there is the danger of the house being shredded mercilessly like dry crackers.

  158. Alex D'Bull says:

    Kudos,Great piece of information. But, your “fear” in condo living or in high rise structures may not be that accurate in my opinion. A Japanese government-funded study of the said fault line indicated that, of the estimated 45% buildings expected to collapse in a major earthquake, 85% of which are low to medium rise structures. In fact, even in the Kobe earthquake, no high rise (30 floors up) structure had collapsed.

    The logic to this are: 1..Most of the older structures are low rise structures and most were not covered by an existing building code. Evident of this are the collapsed century old churches in Bohol where such structures have no steel reinforcements. Even those newer low rise building are more prone to destruction as building code enforcement are not heeded in that level especially in some local government areas where “renovations” are the common excuse for not getting a building permit. The pictures of collapse structures in Haiti clearly shows those buildings were constructed in sub standard manner where steel reinforcement are so visibly sparse and in some cases, lacking or non-existent.

    2. High rise structures tend to “sway” with the earthquake wave compared to stiffer low rise buildings. Its a realization in the structural engineering community in the last 25 years that structures must be built to sway with and not built to fight such violent movement of the earth. While quality of materials, strong foundation, solid bedrock, and good quality workmanship contributes to a stronger structure; the design of such building should be one that can sway with the shaking.

    3.High rise buildings’ foundations are anchored to solid bedrocks as compared to low rise building where foundation footings are the only requirement thus making them more vulnerable to soil liquefaction and subsequent collapse.

    But then, its not just collapsed structures that kills. More deaths usually occurs during panic. If in the event of a strong earthquake happens when one is in the 4oth floor, there is no need to rush down the crowded stairways where injuries and even death is of high probability. There is no question that the Valley Fault Line will certainly move and it may be a strong earthquake, an informed populace can react in a way that it can weather the violent shaking. God bless us all.

    • tulisanes says:

      “sway with the shaking,” that is much like rolling with the punches. i like that! may i share an earthquake docu from japan that i watched where putting a simple steel brace, or a kind of diagonal long metal, near the junction of a concrete post and the beams that it supports spells a lot of difference. with the normal construction of posts and beam, a simulated earthquake transforms the building frame into wobbling jelly or like grasskirt swaying to a hula. but with these braces, the structure did not sway at all like it was one solid piece!

      when you said “sway,” that was the word my office mates used to describe the few seconds they were trying to survive on an 8th floor of a building during the july 16, 1990 earthquake. it seemed the higher one’s elevation when the shaking started, the more tossing to and fro there is in the building. i was on a street then walking and i just watched a 60 foot meralco pole slither upwards like a snake that suddenly grew curves, and the electric lines were going up and down like crazy as if doing skipping ropes. but with my foot planted solid on the ground, it felt like becoming dizzy and losing balance and trying to stay up.

      it’s really something when one puts faith in technology and the technology stands up to it and delivers. personally, as human instinct would have it, when the shaking starts one makes a quick judgment whether the time it takes to find cover in a secure spot is about the same as when one decides instead to head out the door and into the open. to feel secure, i’d rather have clear skies above me within short seconds, where nothing could be falling.

      being on a 40-storey building and hoping that the promise of technology holds up that no structural collapse happens, and with using an elevator a big no-no during an earthquake, the probability of seeing clear blue skies outside anytime soon won’t be happening.

      maybe it’s just me, but when on a 40th floor and the residents going in panic is a given thing, after the initial STRONG tremor, i would rather do something and go down and head out of the lobby door in a zip than just stay inside and meditate on the promise of a brochure that a state-of-the-art engineering was use to erect the high-rise building –so nothing to worry. but hey, it’s just conservative me who won’t go out on a limb and be daring to put faith in technology!

      on a final note, thank God that modern-day engineering keeps getting better and better. however, i tend to think that they hold up to keep us safe longer but not forever. i think of the 911 twin towers where many who evacuated through the long flight of stairs survived than those who opted to stay inside their offices. (i know it’s not fair comparing apples to oranges, but though the CAUSES are different, i find similarity in the EFFECT they impose on the structural integrity of a building).

      hi,

      just my humble opinion, and i claim to be no expert armed with jaded advice. but i don’t recommend living in high-rise condos. i have four reasons why i personally won’t:

      one, WE ARE WARNED by philvolcs that the west valley fault moving is not a question of if but when. the faultline is due to move soon –soon as, perhaps, in the lifetime of the adult generation living today; that is, if we were interpret the recurrence of the quake every 200 to 400 years and we are now in the 350th year since the last time the west valley fault moved.

      meaning, by these numbers alone we can surmise that a west valley quake is long overdue, which we can expect from an adrenalin-pumping imminent (like any time now) to happening within the next 50 years to complete another 400-year max cycle.

      two, the magnitude 7.2 predicted for the west valley fault is similar to 50 megatons of TNT, or “equivalent to that of tsar bomba (50 megatons), the largest thermonuclear weapon ever tested.” remember port-au-prince in haiti that got flattened to the ground by a magnitude 7.0 on jan. 12, 2010? phivolcs hints that when (not if) a 7.2 magnitude earthquake hits metro manila, it can be more disastrous: that while the epicenter in haiti is some 10 kilometers from port-au-prince, the epicenter of phivolcs’ earthquake scenario 08 is WITHIN metro manila.

      while giving it some serious thoughts, here are pictures of devastated haiti to help drive home the point.

      http://www.boston.com/bigpicture/2010/01/earthquake_in_haiti.html

      three, the frequency and magnitude of earthquakes the planet is experiencing in recent years is crazy and anomalous. i know i’ve used this elsewhere in the blog and, maybe, i’ll use it more till it truly catches on. the following graph is as scary as being on a high-rise during an earthquake and being swung wall to wall, to and fro, up there is much, much –way much more traumatic than being on the ground (this is as officemates on the 8th floor of a 14th floor building recounted during the 1990 quake that toppled the hyatt hotel in baguio)!

      ok, if i already live near –maybe 100, 200, and 300 meters, or more even, away from but NOT on– a faultline, i can still take it, provided (1) i live where my family and i can dart out of the house quickly in under one minute (of course, after getting protection from under a table or any sturdy furniture or door jamb during the initial strong quake), and (2) i live on a floor where there is not more than one floor slab above me. God forbid if there are slabs and thick slabs of concrete floor above like in units of these condos that can crash like decks of cards; with narrow hallways in between deadly slabs where, with certainty, everyone in panic clogs into in a mad dash for safety outside. imagine the seemingly endless minutes to get down to the ground past a flurry of wild, fear-stricken people also winding down and almost falling to the bottom of the stairwells!

      four, (this is quite hard to believe specially when crammed into a few short sentences) i believe we are in for some big-time planetary changes that is related to the sun acting up with solar storms starting late 2012, even spewing fiery coronal mass ejections that can be catastrophic if earth is hit. tie it all up to the unprecedented earthquakes experienced around the globe with frequency and magnitudes unfamiliar decades ago. include global warming that is not only happening to the earth but to ALL the planets in the solar system. why this is happening solar system-wide is because the agitated sun and planets are entering a blob of gas ten light years across which NASA scientists call the local interstellar cloud, but which itself is within a much larger expanse of a million-degree hot gas in our milky way called the local bubble….

      QUITE A MOUTHFUL, THESE ARE …DEEPER STILL. actually much more than meets the eye. but by my studies these are the real reasons for the abnormal quakes around the world, and all the reasons more why the west valley fault may be about to wreak havoc. if you don’t understand, pls. google my specific keywords above and be prepared to slide down a rabbit hole.

      “…why are they still building high-rise condos in Fort Bonifacio? Does this mean its safe if you are not on top of the actual faultline?”
      well, simply this: just follow the money trail. it’s all about big bucks real estate and government corruption. you don’t really believe they’d declare vast tracts of prime real estate as no-building zone where there haven’t been an earthquake on the west valley fault for the past 350 years? but give nature a few minutes and everything may just turn into “sahog” to be mixed in a primordial soup.

        Hi Mr. Tulisanes:

        Thank you very much for the reply and apologies for the delayed feedback.

        Your insights have been very helpful in deciding a very important matter. We’re really hopeful a 7-8 magnitude quake, should it eventually strike, won’t cause massive damage.

        Am wondering if we’re the only country that allowed developers to build high-rises near a fault line or is this combination of lax regulation, greed and corruption (assuming these are why high rises were allowed to flourish even with such risks) also brought the same issues and problems in some other countries.

        You don’t really have to answer that sir, was just thinking out loud why people, companies and government will risk the lives of others to (pardon the pun) make a killing.

        Anyway, I’d like to ask (and will welcome a reply if it’s not asking to much) if low-rises (say 6-storey development) that are 5-10 kilometers from the fault line are safe enough?

        Anyway, we’re very grateful for your time and sharing your expertise. More power sir. Cheers

        truth to tell, i think it boils down to whether one lives in a building that sits directly on top of a faultline or not, meaning ten meters or just next to a faultline MAY be prone to the same destructive effects as a farther distance of, let’s say, 10 kilometers. because when a faultline moves, it literally shreds everything on top of it with usually two oppossing forces just like breaking dry soda crackers in two with many crumbling pieces falling by the wayside.

        while it’s true the farther one gets from an epicenter, the lesser the intensity and magnitude of an earthquake, the buildings that are subjected to the destructive forces must be sufficiently strong to withstand the intense shaking. keep in mind that the strength with which a building is built, referring to its structural engineering that is quite invisible to the untrained eye, matters much much more than the esthetic considerations that goes into the architecture, and including any idyllic location and tempting pricing schemes a condo agent offers.

        to answer your question directly: consult a structural engineer about how strong the six-storey development you’re referring to, and make sure you can quickly evacuate yourself and your family SAFELY out of the building, in a given atmosphere of panic, after experiencing the strong initial shock (where earthquake safety cautions one to hide under a strong solid structure like a table till the shaking passes).

      i’ve just had a thought that, maybe, it was intended that we cross paths (yep, pun intended -can’t help it =)

      since you’re suggesting something that you recognize which i can’t, maybe you’d want to contribute your time and observation and help me identify these communities in the maps, and maybe others more, too?

      sort of you’re contributing for the good of humanity (soul-cleansing, too, perhaps). how about it? say yes and i’ll work on how we’ll do it.

      i’ve always been a firm believer in the idea that when you tear down something, make sure that you have something to replace it that people can build on.

      i want to involve you. will you work with me?

      for other readers who also want to help, they can help by sending me screen captures of close-ups of sections of the maps and identify them by naming the file with the name of the villages/communities identified. it will be to my understanding that, at the very vertical center of the screen-captured image is where i’ll put the name as label for the new village/community identified.

        i’ll think so if you think so.

        well, what i mean is obviously you know these areas better than i do. by the way, i never referred to the subdivisions i spelled out in big letters on the upper part as “danger zones.” i placed the names to serve mainly as points or frames of reference so people would have an inkling of the general vicinity of the faultline.

        truth is, i never knew these posh villages lie along what you refer to as danger zones. THANKS TO GUYS LIKE YOU who can identify the areas affected and alert the public to them (surely taxi and bus drivers have better luck in naming these areas than i). i picked out these subdivisions from what were already identified and could be read in the outdated philvolcs map.

        regarding your comment below that i’d be more thorough when i broadcast something, i just couldn’t be anymore thorough after spending more than a month assembling the maps with about three hours that i put in daily. it was nerve-wracking that i later had to force myself to finish the maps! if you create maps this big a size and want them detailed too, there’s a chance halfway through you’ll get stuck in a rut and unable to go on with a case of paralysis from analysis.

        though even if not thorough as you put it, i think of it as a POINT IN THE RIGHT DIRECTION. i’d rather that people recognize the “thoroughness” in my attempt to make the street names readable while creating the maps with file sizes just under 1 megabyte that you can email easily. a mean feat if you ask any serious graphic artist.

      Actually it is not much for purchasing land with informed decision that i made the maps on this blog (though i’m glad i can help in that area). the maps are there to help those who want to be helped to keep out of harm’s way, particularly people who live or work practically on top of the faultline.

      even phivolcs tells outrightly it is not a matter of IF but WHEN an earthquake will shake the marikina valley faultline system (mvfs). how i read it: it’s earthquake coming soon….

      i found a site that puts into chart all the deadly and destructive earthquakes worldwide between magnitude 6 and 8 that occured in the past century, from 1900 to 2008 (i wonder why it stopped there), with the UNITED STATES GEOLOGICAL SURVEY as source of data.

      the abrupt spike in the rise and frequency of destructive earthquakes since the start of the millennium is just unbelievable. it just increases the chances of the mvfs moving soon.

      i’m not familiar with the area, but i did some checking on google earth with an overlay of the fault trace. to give you a picture of where the faultline lies, try zooming in on the area (where the west fault ends), locate the PNR muntinlupa station, the PNR carmona station, and the de la salle canlubang. imagine a line connecting those points and there the faultline crosses –but not a neat, straight line really; more like a series of inverted “V” tracks that become parallel lines for some distance, then to join again to form a letter “V” after de la salle canlubang.

      basically what this shows, after jumping from the map mode to the aerial, real view of the satellite mode, is that the faultline for the most part crosses rugged, green country. though the heavily populated area are way over to the right of the faultline, there appears to be some subdivisions with houses scattered far and wide from each other across many vacant lots through where the faultline passes.

      it also appears the fault trace just stops after de la salle canlubang. though relatively very near the school, the faultline DOES NOT pass through the school grounds.

      by the way, “sta. rosa city” can be read at the center of the heavily populated area i referred to earlier –my basis for citing the above for your sta. rosa question.
