Emergency responders holding exercise to test response readiness to earthquakes

'Great State Shake' program comes after 3 small quakes rattle area Sunday

Emergency responders from California, Alaska, Arizona, Colorado, Nevada and Washington are participating in a disaster exercise this week to test their response in the event of a 6.8-magnitude earthquake in the Bay Area.

The exercise comes two days after two small earthquakes struck within minutes of each other in the East Bay near Mount Diablo Sunday afternoon, and a third occurred near The Geysers in Sonoma County.

As part of the drill, the earthquake will simulate the loss of and damage to major infrastructure resources. Major bridges, drinking water supplies, wastewater treatment facilities, and chemical and radiological facilities could potentially be impacted if such a quake were to rock the Bay Area.

The simulated earthquake along the Hayward Fault is a collaborative effort between the U.S. Environmental Protection Agency offices in Denver, Seattle and San Francisco, the U.S. Coast Guard and California's Department of Toxic Substances Control.

The exercise, called the Great State Shake, now under way, ends Thursday.

The first of Sunday's small earthquakes, according to the USGS, was a 3.2 magnitude earthquake that struck shortly before 3:55 p.m. in an area seven miles south-southwest of Brentwood and eight miles east-northeast of Blackhawk. About two minutes later, a 2.8 magnitude earthquake struck in the same location, according to the USGS.

The 3.2 magnitude earthquake had a depth of 7.2 miles, while the 2.8 magnitude had a depth of 6.6 miles, according to the USGS.

A 2.9 magnitude earthquake also struck in the North Bay Sunday. According to the USGS, that quake struck shortly after 3:30 p.m. and had a depth of 1.3 miles. It was centered five miles east-southeast of The Geysers and 16 miles east of Cloverdale, according to the USGS.

There hasn't been a major quake from the Hayward Fault line in over 140 years. They also recently discovered it's connected to the San Andreas fault line and say it's going to be 4 times worse than expected if both go off in a major way. It's over due (Hayward fault line) to go anytime, be prepared, and live everyday to the fullest.

Steve, thanks for the link. Unfortunately, I found the website cited very poorly-designed. What I (and other readers, I'm sure) *really* want to know is what activities will be taking place in or around Pleasanton. The way it's set up, one needs to click on the type of organization, then the county, only to find there's no activity for that "type of organization", e.g. "Schools" or "Medical Organizations" or "Faith-based organization" here in Pleasanton, multiple tries.

If anyone knows of any LOCAL activities we can participate in, please do post. Sorry to be a wet blanket, but it's not really well-structured.

And just for clarification, the actual anniversary of Loma Prieta is 10/17. I initially assumed that they were observing it on the 15th because it was a weekend day and easier for those of us who work, but *No*, the 15th is a Thursday and even harder for working folks to participate, unless our employers give us time off, which is unlikely... so, what the heck? Any ideas about why this approach?

Sorry, but further commenting on this topic has been closed.
