This is a big week in U.S. (and world) earthquake history. In the U.S. we mark the anniversaries of several major, important earthquakes that have struck the country.
On October 15, 1979, a M6.9 earthquake struck the Imperial Valley of southern California/northern Baja. In 2006 a M6.7 earthquake rocked the island state of Hawaii, damaging thousands of buildings at a cost of $73 million. On October 16, 1999, people throughout the U.S. southwest were rolled from their slumber by the massive M7.1 Hector Mine earthquake that struck the Mojave desert at 2:46am. And of course… on October 17, 1989, the Battle of the Bay baseball World Series was interrupted in San Francisco by the devastating M6.9 Loma Prieta earthquake. …And let’s not forget the 1935 M6.3 Helena, Montana earthquake of October 19, part of a series that cost the city dearly, and should serve as a reminder that the intermountain west and the Rocky Mountain front are not free from seismic danger.
Capitalizing on that spate of anniversaries, and on the early date in the U.S. school year, a host of quake-dedicated agencies have organized the fifth annual ShakeOut drill.
This year the drill has expanded far beyond California, incorporating participating agencies in countries around the world. The U.S. is divided into official ShakeOut regions, including many individual states and some at-risk regions like the New Madrid seismic zone, each with their own specific issues when it comes to earthquake hazard. Nearly the whole country is covered, so I encourage ALL of you to sign up and Shake Out.
In most of the U.S. the drill takes place on Thursday, October 18, at 10:18am. In the Central U.S. the drill will take place on February 7, to mark the largest of the 1811-12 New Madrid quakes, and Utah will hold theirs on April 17. Participation is voluntary, unless your employer or educator has opted in for you, but already one third of California’s population is registered. Globally, 17 million people are signed up. Of course it behooves everyone to know what to do in an earthquake, and what resources you will have available, so there’s hardly any reason not to join in.
Visit http://www.earthquakecountry.info/ for information on what to do before, during, and after an earthquake, and to obtain resources for your own drill. Every family that faces the threat of earthquakes (that’s all of you) should know how to find each other and cope with the aftermath. You should also brush up on your Drop, Cover, and Hold On. No doorways. No triangle of life. No sprinting down the stairs to the street like a frantic animal. Stay in place and get under something sturdy. The Earthquake Country Alliance has put together an informative set of instructions on how to protect yourself in a wide variety of situations.
Sign up for the drill, and get the word out to your friends and coworkers. This is invaluable practice. We can’t predict earthquakes, but we do now how to deal with them. The best defense we have as individuals is our own awareness and preparation.
