This quake did not begin to exhaust the pent-up energy in the 800-mile-long San Andreas system. In a list of seismic danger zones compiled by an expert panel last year, the section around Santa Cruz ranked only sixth. The area believed most likely to have a devastating quake...
Still, there is a vast difference between suggesting that an earthquake is likely to happen and pinpointing when. For now, scientists cannot say whether a specific section of the San Andreas fault will snap in one year's time or in a hundred, but they are working on it. Seismic silence is one clue. Soundings taken along the San Andreas over the past 15 years showed that the small earthquakes that are a daily event along other parts of the system were not occurring in the Santa Cruz mountains. Scientists argued over the significance of this blank spot...
...perhaps with their fingers crossed, had promised that the Webster decision would galvanize a silent pro-choice majority. Last week, as pro-choice activists won stunning victories in Florida's legislature and the U.S. Congress, that promise began to be fulfilled. With the political landscape seeming to undergo a seismic shift, many antiabortion politicians have concluded that the only way to maintain their footing is to tiptoe away from their former positions...
Nonetheless, last week's seismic developments in Poland reverberated from Moscow to Washington and beyond. The Kremlin said Jaruzelski's decision was Poland's business, but the success -- or failure -- of a government led by a & non-Communist in Warsaw is bound to have an impact on Mikhail Gorbachev's political reforms in the Soviet Union. The West applauded carefully, wary that too hearty a response might be considered meddling that could unbalance the delicate experiment. "We would encourage a non-Communist government in the process of pluralism, of course," said presidential spokesman Marlin Fitzwater. But George Bush "would...
...telltale seismic-wave patterns also suggest that while the sun's outer layer rotates faster at the equator than at the poles, the inner region rotates uniformly. This creates a shear force, like the blades of scissors sliding past each other, that Harvey suspects distorts the magnetic field, giving rise to the solar cycle...
