Yes, we live in Earthquake Country

Filed under: — stan @ 9:11 am

Today there was a copy of “Putting Down Roots in Earthquake Country” included with the morning paper. Over the last ten years, I’ve handed out many of these booklets at disaster preparedness fairs all over L.A. I’m glad to see it getting wide distribution with the Times.

Next week is the 100th anniversary of the 1906 San Francisco Earthquake, which was the event that pretty much started all of modern earthquake science. This is what led ultimately to the current understanding of the earthquake cycle and why we need to be prepared for earthquakes. And in some small way, it’s also what led my having a job running the computers for the Southern California Seismic Network. (Have I mentioned ever that I really like my job?) And I even got to contribute a little bit to the book. I made the map on page 30, showing the first hour’s activity after the 1994 Northridge Earthquake. The ‘recent earthquakes‘ maps didn’t exist back then, but I took a catalog listing of the first hour’s earthquakes and fed them into the map program to simulate what it would have looked like.

So for everyone who lives in California, keep watching the ground. And for everyone who doesn’t, Nyeah, Nyeah! there are earthquake hazards in lots of other places, too.

    Well as you know Illinois has many earthquakes and is prone to them particularly in the southern portions.

    So earthquake dangers are not off the radar screen just cause I don’t live in CA (just not a hazard to end up falling into the ocean!)

    Yup. I remember a few years ago there was a M5.0 in southern Indiana. That made for an exciting afternoon. There’s apparently a school of thought that all the earthquakes in that region are just aftershocks of the 1811-1812 New Madrid sequence. They were so big that it’s not all that far-fetched that they could still be having aftershocks nearly 200 years later.

    Earthquakes are as Southern Californian as waves at the beach and traffic on the freeways. Let us pray for god without earthquakes world..
