The video show you what not to do during an earthquake. You never panic
and run out of the building into the streets. Many of the fatalities are caused
by falling debre such as glass, cement, etc.
I lived in California and experienced the 1971, and the 1994 earthquakes.
Because of the earthquake drills I was in during my school years I got
under a doorway, or under a desk. Because of the practice drills, I am
conditioned not to panic, but get in the safest place.
Earthquakes usually last about 30 seconds. Than expect aftershocks some
greater or lessor magnatude.
