Hi All. There seems to be some difference of opinion with the USGS. Take Care…Don in creepy town

“In a paper presented Wednesday at the Seismological Society of America meeting, seismologist Tousson Toppozada, an expert on California earthquake history, noted that there has been a distinctive pattern associated with the four major earthquakes in the Bay Area since 1800. That pattern indicates the possibility of increased activity 15-20 years after the magnitude 7.0 Loma Prieta earthquake.”

“If historical trends are an indication, the San Francisco Bay Area -- relatively quiet since the 1989 Loma Prieta earthquake -- is likely to experience potentially damaging earthquakes in the next four to nine years, according to research conducted by the California Department of Conservation's Division of Mines and Geology.”

"We really don't know how long the current quiescence in the San Francisco Bay Area can last, but we know it can't last forever. If the past is any indication of the future, we can expect some potentially damaging earthquakes within the decade, possibly by 2004."
