...intervals between eruptions along the big faults are measured in centuries, whereas the secondary cracks ``may only slip in a big earthquake every 1,000 to 5,000 years,'' notes seismologist Wayne Thatcher of the U.S. Geological Survey. ``Yet there are so damn many of them that they pose a seismic hazard equivalent to the Big One we've all been so focused on.'' Seismologists also point out that quakes could endanger places where citizens have rarely thought about them: Seattle, for instance, which sits close to a fault under the Pacific that seismologists now conclude has triggered major quakes...
What scientists fear is that the southern San Andreas has reached a similarly critical threshold. "If the Landers earthquake put a little stress on the San Andreas," exclaims Allan Lindh, chief seismologist of the U.S. Geological Survey, "then what about the accumulated stress of 300 years of plate motion?" For Lindh and other experts, the Landers quake and its resulting tremors are all too reminiscent of the increased seismic activity that preceded the great San Francisco blowout of 1906. "I mean," says Lindh, with a dramatic pause, "how much more on the edge of our chairs...
...inheritance from an ethically questionable chemical company once operated by his grandfather. Fuel to the fire comes in the form of a peculiar series of earthquakes which are beginning to threaten the New England area. And if that weren't enough, Renee--an older, unattractive, brilliant and insecure Harvard seismologist with strong feminist tendencies, whom Louis finds himself falling reluctantly in love with--discovers that these turbulent terrestrial tremors could very well be the result of the avaricious and corrupt conduct of Louis' grandfather and his cohorts...
...head of the department of engineering and public policy at Carnegie-Mellon University. But after last week, earthquakes are going to be viewed as a much more persistent risk than they were before. That will force many communities to choose which risks to take seriously. Says Bruce Bolt, a seismologist at the University of California, Berkeley: "If you have only a certain amount of dollars to spend on risk mitigation in a particular area, do you spend it on seismic upgrading or on asbestos removal...
...spaced further apart than small ones, since it takes a much longer time to accumulate sufficient stress. While scientists cannot say exactly where or when the next Big One will hit, they are not without hunches. Southern California, which has not had a Big One since 1857, is every seismologist's first...
