WHAT TO DO IMMEDIATELY WHEN SHAKING BEGINS
Your past experience in earthquakes may give you a false sense of
safety; you didn’t do anything, or you ran outside, yet you survived
with no injuries. Or perhaps you got under your desk and others thought
you overreacted. However, you likely have never experienced the kind
of strong earthquake shaking that is possible in much large earthquakes:
sudden and intense back and forth motions of several feet per second
will cause the floor or the ground to jerk sideways out from under you,
and every unsecured object around you could topple, fall, or become
airborne, potentially causing serious injury. This is why you must
learn to immediately protect yourself after the first jolt… don’t
wait to see if the earthquake shaking will be strong!
In MOST situations, you will reduce your chance of injury if you:
- DROP down onto your hands and knees (before the earthquakes knocks you down). This position protects you from falling but allows you to still move if necessary.
- COVER your head and neck (and your entire body if possible) under a sturdy table or desk. If there is no shelter nearby, only then
should you get down near an interior wall (or next to low-lying
furniture that won’t fall on you), and cover your head and neck with
your arms and hands.
- HOLD ON to your shelter (or to your head and neck) until the shaking stops.
Be prepared to move with your shelter if the shaking shifts it around.
Wherever you are, protect yourself! You may be in situation
where you cannot find shelter beneath furniture (or low against a wall,
with your arms covering your head and neck). It is important to think
about what you will do to protect yourself wherever you are. What if you
are driving, in a theater, in bed, at the beach, etc.?
Step 5 of the Seven Steps to Earthquake Safety describes what to do in various
situations, no matter where you are when you feel earthquake shaking.
HOW PEOPLE WITH DISABILITIES CAN PROTECT THEMSELVES
WHY RESCUERS AND EXPERTS RECOMMEND
DROP, COVER, AND HOLD ON
Trying to moving during shaking puts you at risk: Earthquakes
occur without any warning and may be so violent that you cannot run or
crawl; you therefore will most likely be knocked to the ground where you
happen to be. So it is best to drop before the earthquake drops you,
and find nearby shelter or use your arms and hands to protect your head
and neck. “Drop, Cover, and Hold On” gives you the best overall chance
of quickly protecting yourself during an earthquake… even during
quakes that cause furniture to move about rooms, and even in buildings
that might ultimately collapse.
The greatest danger is from falling and flying objects:
Studies of injuries and deaths caused by earthquakes over the last
several decades show that you are much more likely to be injured by
falling or flying objects (TVs, lamps, glass, bookcases, etc.) than to
die in a collapsed building. “Drop, Cover, and Hold On” (as described
above) will protect you from most of these injuries. If there is no
furniture nearby, you can still reduce the chance of injury from falling
objects by getting down next to an interior wall and covering your head
and neck with your arms (exterior walls are more likely to collapse and
have windows that may break). If you are in bed, the best thing to do is
to stay there and cover your head with a pillow. Studies of injuries in
earthquakes show that people who moved from their beds would not
have been injured if they had remained in bed.
You can also reduce your change of injury or damage to your
belongings by securing them in the first place. Secure top heavy
furniture to walls with flexible straps. Use earthquake putty or velcro
fasteners for objects on tables, shelves, or other furniture. Install
safety latches on cabinets to keep them closed. Instructions for how to
“secure your space” are at www.daretoprepare.org.
Building collapse is less of a danger: While images of
collapsed structures in earthquakes around the world are frightening and
get the most attention from the media, most buildings do not collapse
at all, and few completely collapse. In earthquake prone areas of the
U.S. and in many other countries, strict building codes have worked to
greatly reduce the potential of structure collapse. However, there is
the possibility of structural failure in certain building types,
especially unreinforced masonry (brick buildings), and in certain
structures constructed before the latest building codes. Rescue
professionals are trained to understand how these structures collapse in
order to identify potential locations of survivors within “survivable
The main goal of “Drop, Cover, and Hold On” is to protect you from falling
and flying debris and other nonstructural hazards, and to increase the
chance of your ending up in a Survivable Void Space if the building actually
collapses. The space under a sturdy table or desk is likely to remain even
if the building collapses- pictures from around
the world show tables and desks standing with rubble all around them,
and even holding up floors that have collapsed. Experienced rescuers
agree that successfully predicting other safe locations in advance is
nearly impossible, as where these voids will be depends on the direction
of the shaking and many other factors. (See “triangle of life” below.)
The ONLY exception to the “Drop, Cover and Hold On” rule is if you
are in a country with unengineered construction, and if you are on the
ground floor of an unreinforced mud-brick (adobe) building, with a heavy
ceiling. In that case, you should try to move quickly outside to an
open space. This cannot be recommended as a substitute for building
earthquake-resistant structures in the first place!
WHAT RESCUERS AND EXPERTS *DO NOT* RECOMMEND YOU DO DURING AN EARTHQUAKE
Based on years of research about how people are injured or killed
during earthquakes, and the experiences of U.S. and international search
and rescue teams, these three actions are not recommended to protect yourself during earthquakes:
DO NOT run outside or to other rooms during shaking: The area
near the exterior walls of a building is the most dangerous place to be.
Windows, facades and architectural details are often the first parts of
the building to collapse. To stay away from this danger zone, stay
inside if you are inside and outside if you are outside. Also, shaking
can be so strong that you will not be able to move far without falling
down, and objects may fall or be thrown at you that you do not expect.
Injuries can be avoided if you drop to the ground before the earthquake
DO NOT stand in a doorway: An enduring earthquake image of
California is a collapsed adobe home with the door frame as the only
standing part. From this came our belief that a doorway is the safest
place to be during an earthquake. True- if you live in an old,
unreinforced adobe house or some older woodframe houses. In modern
houses, doorways are no stronger than any other part of the house, and
the doorway does not protect you from the most likely source of injury-
falling or flying objects. You also may not be able to brace yourself
in the door during strong shaking. You are safer under a table.

DO NOT get in the “triangle of life”: In recent years, an e-mail
has been circulating which describes an alternative to the
long-established “Drop, Cover, and Hold On” advice. The so-called
“triangle of life” and some of the other actions recommended in the
e-mail are potentially life threatening, and the credibility of the
source of these recommendations has been broadly questioned (see links
The “triangle of life” advice (always get next to a table rather than underneath it) is based on several wrong assumptions:
- buildings always collapse in earthquakes (wrong- especially in developed nations, and flat “pancake” collapse is rare anywhere);
- when buildings collapse they always crush all furniture inside (wrong- people DO survive under furniture or other shelters);
- people can always anticipate how their building might collapse and anticipate the location of survivable void spaces (wrong- the direction of shaking and unique structural aspects of the building make this nearly impossible) ; and
- during strong shaking people can move to a desired location (wrong- strong shaking can make moving very difficult and dangerous).
Some other recommendations in the “triangle of life” e-mail are also
based on wrong assumptions and very hazardous. For example, the
recommendation to get out of your car during an earthquake and lie down
next to it assumes that there is always an elevated freeway above you
that will fall and crush your car. Of course there are very few
elevated freeways, and lying next to your car is very dangerous because
the car can move and crush you, and other drivers may not see you on the
ground! A compilation of rebuttals from many organizations to these
alternative recommendations, as well as news articles about the
controversy, is listed at left
