What to do in an earthquake

What to do in an earthquake - read the supported advice -

an article from the website of  Earthquake solutions

In recent months an e-mail article has been widely circulated, under the title “The Triangle of Life” written by Doug Copp of ARTI (American Rescue Team International).  It has led many people to question or plan to change their response to heavy shaking, and some of the recommendations in the article have even been repeated in media stories as if they were fact.

Some real earthquake safety facts to know:

(The following comments are made in particular for high-magnitude quake situations, and with special concern for those people who may be at or near the epicentral regions when they occur.  Seismic forces generally dissipate fairly rapidly with distance.  What you have "felt" in past earthquakes, may not be what you experience during the next one, particularly if your location is closer than you have ever been in the past.  Also, near the epicentral areas, there is much less time in which to react.)

1)      “Drop, cover & hold on” is still the recommended action to take  during the shaking according to all major and credible earthquake  safety authorities.

2)      You are more likely to be killed or injured from building contents and imploding glass than from structural collapse.  To protect yourself from these hazards,

a)      Contents of homes, offices and schools should be braced or secured with proper seismic restraint devices, AND …

b)      You must also take protective cover within three seconds or less during an actual earthquake.

3)      Getting under a table is not always necessary, but cover should always be used when it is available, if it is available within the three-second rule.

a)      Contrary to Copp’s claims that cover will “always” crush the victims, numerous actual post-earthquake studies show clear evidence that cover helps to protect the victims from injury from flying building contents and imploding glass, AND…

b)      Cover can provide crucial support in the event of structural collapse.  For instance, in one earthquake, one building had student desks that consist of merely a chair with a writing arm, and it was the writing arms of those desks that held up the collapsing story from above.

4)      It is better to drop, cover & hold on within three seconds, even if no table is immediately available to get under, than to attempt to get to another “safer” location.  The time element is critical.

a)      Victims who try to move on their feet during serious shaking are often thrown violently by the seismic forces and can suffer serious injury from being thrown AND…

b)      Are at risk for suffering life-threatening injuries from being simultaneously imbedded with glass shards.  Actual post-earthquake data show that large and dagger-like shards of glass can travel more than 20 feet, and with enough force to penetrate solid wood.  If you are attempting to move on your feet, your entire body is exposed to glass and other objects that can forcefully fly from every direction.
