OFFICIAL RESCUE TEAMS from the U.S. and other countries who have searched for trapped people in collapsed structures around the world, as well as emergency managers, researchers, and school safety advocates, all agree that "Drop, Cover, and Hold On" is the appropriate action to reduce injury and death during earthquakes. Methods like standing in a doorway, running outside, and "triangle of life" method are considered dangerous and are not recommended (see below).
Topics addressed below include:
- What to do wherever you are when shaking begins

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 larger 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 earthquake knocks you down). This position protects you from falling but allows you to still move if necessary.
- COVER your head and neck with both arms, clasping your neck with your hands. If a sturdy desk or table is nearby, crawl beneath it while keeping one arm over your head. (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 a 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.

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.
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 chance 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.earthquakecountry.org/step1.
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 void spaces."
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 drops you.
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.

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 on the right.
PRACTICE THE RIGHT THING TO DO… IT COULD SAVE YOUR LIFE
You will be more likely to react quickly when shaking begins if you have actually practiced how to protect yourself on a regular basis. A great time to practice Drop, Cover, and Hold On is by participating in a Great ShakeOut Earthquake Drill (each October in most areas).
