The Bay Area Is Living In Denial

Hi All. Over the past decade I have talked to people about the next quake in the Bay Area. Most of them aren’t ready. They all say we survived the Loma Prieta quake so we shouldn’t have too much trouble with any quake here. The problem with this thinking is that the Loma Prieta quake wasn’t in the Bay Area. There is a world of difference in the shaking from a quake that is 60 miles away and one that is right underneath you.

From a survey done a couple of years ago it was found that about 40% of the people have prepared for the quake. Most however believe it won’t occur in their lifetime.

Every day that passes with out a quake just means that when it does occur, and it will occur as it is just a matter of time it will be larger then it would have been had it occurred last year, or the year before.

The following is from Dr. David Schwartz of the USGS in Menlo Park. Take Care…Don in creepy town

Some quakes are so powerful they leave the earth speechless. The Great San Francisco Earthquake of 1906, a massive 7.8 quake, shook the region so violently that scientists believe it cast a calming "shadow" over a half-dozen parallel faults, sending the entire Bay Area into a long seismic sleep.

In the seventy years leading up to the catastrophic day, at least fifteen quakes measuring 6.0 to 6.9 slammed the Bay Area. But since the morning of April 18, 1906, when the ground convulsed for nearly a minute, there has been precious little activity -- nothing exceeding a 6.5 on the infamous San Andreas; nor the Calaveras, which flanks I-680 through Pleasanton and Danville. The Hayward Fault, which cuts through the East Bay Hills, has remained essentially idle. Ditto the San Gregorio, Rodgers Creek, Concord-Green Valley, and Mount Diablo faults. These giants have been slumbering in relative peace for the better part of a century -- which is striking given that the region's soaring hills and deep valleys were formed by countless millennia of seismic upheaval. "The Bay Area has the highest density of active faults per square mile of any urban center in the country, and on a long-term basis it has the highest amount of earthquake energy released per square mile of any urban center in the country," says David Schwartz, a geologist with the US Geological Survey. "So we're really kind of living at ground zero."
