Re: [Geology2] reply to Mexico quake.

Hi Allison,

I understand your problem. Where a quake occurs plays a major difference in how one should react. Here in the midwest, we won't have a warning system for quite some time, so the standard Shake Out response is Drop, Roll under something sturdy, and Hold on.

 On the left coast, though, with a 30 second warning, and having the forethought of what to do in mind, you would already know the safest way to proceed given the sirens' notice. On a 30 story level, stay put, do the Shake Out maneuver. On the ground floor? Here's where you'll need to know the architecture of your building... do you have a "tuck-under" garage? If so, get out. The garage will collapse and the basement and first floor will be history in a large enough quake. If you are in a building that has been retrofitted or has rebar within its construction, then you should stay put. Know where power lines are. Know where your gas and water cut-offs are. Know where the breaker box or fuse box is.

It's not  a simple thing to plan, and that's where the Shake Out sites are great at offering suggestions on how to react during and after a large quake. My earlier response was given with the knowledge that one could safely get out of a building within certain (simple) parameters. But if you get out only to be found in a maze of electrical hazards or other considerations, then you are better off inside under cover.

There is no one way to ensure your survival, but you'll need to know in advance what to do and not wait for a real quake to teach you.

Back in Houston, we kept emergency supplies of water. There were a few times when a hurricane or tropical storm would make it necessary. But a quake... I have never drilled for a quake and never thought in those terms. And put a lot of "ifs" there. I suppose there is a general plan for an earthquake? But I don't know what that is and there are an awful lot of  folks who dont' know what that is...having never lived in earthquake country. Say I am in downtown Los Angeles. Do I head for the  street? Go to the basement? That is what i do in the event of a tornado. Get under something? What? Do I head for the hills? Am I gonna make that in 30 seconds? see my problem. Allison
