3) Wooden buildings are the safest type of construction to be in during an earthquake. Wood is flexible and moves with the force of the earthquake. If the wooden building does collapse, large survival voids are created. Also, the wooden building has less concentrated, crushing weight. Brick buildings will break into individual bricks. Bricks will cause many injuries but less squashed bodies than concrete slabs.
In California most residential homes are wood frame, BUT we don't have hurricanes to contend with, so for us it's the safest construction. In the Caribbean, though not so much in Trinidad you have to strike a balance - The cinder block is more common. (I still don't know why getting a house build that way in Florida is such a problem. A lot of contractors don't seem to like it.
This thread has mentioned a lot about what to do during an earthquake, but not what to do after. One of the biggest hazards after is fire especially due to ruptured gas lines. Knowing were to shut off your gas main is important - but only do it if there is damage to the line - and having a wrench handy. Fasten or hang a wrench near the valve and keep it there.- A great way to make a buck in California is going door to door with wrenches painted bright neon colors to fit the gas mains.
Other stuff:
-Damaged electrical wiring: Shut off power at the control box.
-Downed or damaged utility lines: Stay away from downed lines even if power appears to be off.
-Fallen objects in closets and cupboards: Displaced objects may fall when you open the door.
-Check your telephone: Make sure each phone is on its receiver. Telephones that are off the hook tie up the telephone network unnecessarily.
-Clean up potentially harmful materials and/or medicines which may have spilled. -Use flashlights or battery-powered lanterns. Do not use lighters, matches, candles, or lanterns until you are sure there are no gas leaks.
-Use your telephone only in the event of life-threatening emergencies.
-Turn on a battery-powered radio for information, damage reports, and for information on volunteering your assistance.
-Keep streets clear for emergency vehicles. Cooperate with public safety officials.
