Question now is, what sort of thing can happen in the red patch area?



Read part 1 first.

Note:   the road that is a yellow line cutting through the red patch is MARCOS HIGHWAY; while the yellow line traversing the pink and then goes between the pink and red areas is SUMULONG HIGHWAY. Where these two lines intersect is Masinag. Notice also the faint bright green lines that are sort of “secret” fault lines that Phivolcs is not telling? These may well explain the unexplained danger the “red patch” hides.


Can it be in the red patch area are the slopes of mountainside that will further drop when compromised land mass breaks off at its junction to these faults, as triggered by a 7.2 magnitude quake? Notice the “scooped” stretch along Marcos Highway, where an ocular visit to the area reveals rising  hills and mountains on one side while the other side is likewise rising with access roads to Sumulong Highway via Blue Mountain and Olalia Drive on Gate 2. It is the same rise in elevation that can be observed when driving along Sumulong Highway from Brgy. Mambugan to Valley Golf Subdivision and onward to St. Benilde College and so on.


The “valley” aspect (ground depression) when the east and west valley faults formed never quite followed suit along the stretch of Marcos Highway where the ground rises on its sides as mountain slopes. But the next predicted powerful earthquake may just turn the shallow scoop into a deep valley when the same land mass drops further by several tens of feet!


How big is the drop? If it is any indication, the disparity in the ground elevation of Katipunan Ave. in Quezon City and the Industial Valley Subdivision in Marikina, where these two are connected by a looping short road called Bitukang Manok, or the back of Ateneo University which is actually a ravine for the lowland Brgy. Barangka in Marikina below it, a vertical ground movement on the tell-tale red patch in Antipolo may just imitate this valley effect.

Though it is not a sink hole, but by another mechanism it can likewise have a disastrous effect with mass landslides triggered.


Videos, anyone? (you have to download them first.)

This blog was started in 2013; however, it actually began in 2010 but got corrupted and backups of the original helped to restart the present blog. Prior to 2010, i was emailing people Google maps with the fault trace. But it was in 2005 when i assembled my first map. In 1990, i got ahold of a photocopy of a tabloid size, black and white map when the former Phivolcs head, the late Ricardo Punongbayan gave an earthquake awareness seminar after the July 16 earthquake. i put away the map inside a cannister and rediscovered it 15 years later when i was going through my old stuff. Instantly, sirens went off inside my head and took stock of the situation on what i had: Windows in my computer (DOS ruled PCs 15 years earlier), Adobe Photoshop, a powerful image scanner and, most of all, a coffee table book of tiled large maps of Metro Manila. Fancying what i could accomplish with technology and a 15 year old map, i put my competency at work and scanned images and assembled them on my desktop computer. Lo and behold, even after checking the work several times, i got the jolt of my life when i discovered my rented house was actually sitting on top of a fault line! Not long after, i evacuated and resided far from any faultline. At the time, i was probably one of the few (not that i know anyone else) who assembled a map of the fault line. What were the chances that i assemble a fault line map as a weird activity and suddenly find myself and my family at risk and unaware that a silent, deadly fault line ran directly under our house. It was an epiphany! Since then i knew what i had to do, and God brought everything to pass easily and smoothly. However, truth to tell, creating the maps was so nerve-wracking and I could not have done it all if I weren’t a bit of obsessive-compulsive in me. For many months, everyday I had to devote about four hours piecing together up close snapshots of many topographical maps and later google maps to create this blog. I could say i literally spent tens of kilometers after kilometers assembling detailed maps and from the experience, I made many observations that I made posts of. The gratifying moment came when Phivolcs and the NDRRMC maybe through an influential follower of my blog, I suspect, launched a media blitz with campaign to protect the welfare of students whose schools, and many they are, are in the path of fault lines. I knew my work became basis of this and I couldn’t help but feel that i had accomplished at least one of my life’s purpose. i may just be accomplishing God’s will; but then again, maybe not. Only God knows. “There will be great earthquakes, and there will be famines and plagues in many lands, and there will be terrifying things and great miraculous signs from heaven.” -Luke 21:11 “At that very hour there was a severe earthquake and a tenth of the city collapsed. Seven thousand people were killed in the earthquake, and the survivors were terrified and gave glory to the God of heaven.” -Revelations 11:13 “Nation will rise against nation, and kingdom against kingdom. There will be famines and earthquakes in various places.” – Matthew 24:7 * * * * * * * * * * * * * * * * * * * * * * * * “Therefore will not we fear, though the earth be removed, and though the mountains be carried into the midst of the sea;” -Psalm 46:2 * * * * * * * * * * * * * * * * * * * * * * * *

    Thank God I stumbled upon this article/report/data. We were connsidering buying a multi million house in Antipolo (30 years of hard earned money pooled together).

    ang nuvali po ba kasama sa west valley fault line

    Mr. Tulisanes, so any movement on the west valley fault will for sure trigger movement on the unnamed faults in Rizal ( faint green faults on your article above)? I am assuming this was included on the studies of Philvocs for risk assessments with the Japanese and Australian agencies. Or has Philvoc’s lack of data anything to do with funding? This then becomes the real problem. But thank you for the information your provide.

    To truly understand what we are talking about in your article, I watched earthquake simulations on you tube (like the San Andres fault). While it helped me understand what an earthquake might possibly do, I am just out of words now.
