Using computers for seismic surveys, and new drilling technologies to dig deeper, geologists are looking everywhere, from the frozen Arctic to the jungles of Africa and South America. With bet-a-billion gusto, they are searching for new energy Eldorados...
...estimated to be about 40 years behind that found in the West. The standard Soviet turbodrill, for example, bores much more slowly than American equipment. It takes a Soviet team 14 months to dig down 10,000 ft.; U.S. drilling teams can reach that depth in 34 days. Seismic technology, essential for exploration, also lags far behind. The best Soviet gear probes down to 7,000 ft.; U.S. equipment is more accurate and goes down to at least 10,000 ft. Given the state of their industry, says Meyerhoff, "there is simply no way that the Soviets are going...
...jitters of beleaguered residents, two moderate earthquakes suddenly jolted Mount Margaret, a peak only 13 km (eight miles) northeast of Mount St. Helens. Though scientists emphasized that these seismic disturbances were not hints of an impending eruption, the tremors only added to what might be called a case of tectonic fever on the West Coast. Hundreds of small earthquakes shook the Sierra Nevada in central California, causing landslides and some injuries. At least 100 of the quakes measured above 4.0 on the Richter scale and three reached 6.0 or higher, levels at which there would have been more widespread destruction...
