...geologist reports that two major earthquake-prone faults in southern California have achieved synergy. An 1857 rupture of the San Andreas fault, he says, has been triggering aftershocks on the nearby San Jacinto fault ever since. If he's right, the next great earthquake near the Mexican border will happen 20 years from...
...evidence suggests that earthquakes are incremental steps in the movement of the 20 or so lithospheric plates that make up the planet's crust. It takes about 50,000 major jolts to nudge a plate 100 miles. Eldridge Moores, the geologist who guides McPhee, believes California was formed when a 2,000- mile-long arc of land parked against North America 250 million years...
...volcano seemed to take a big breath, first sucking in air, then exploding," said a Colombian tourist who survived unhurt. Garcia and Menyailov died in an instant in the 600 degreesC blast of toxic gases. On the western rim of the cone, British geologist Geoffrey Brown and two Colombian colleagues were also incinerated as gas and heat spurted upward...
ONCE A MONTH, AS THE MOON WANES, GEOLOgist Eugene Shoemaker, 64, and his wife Carolyn, 63, leave their house in Flagstaff, Arizona, load warm clothes into their station wagon and set off to the west on an 800-km (500-mile) trip across the desert. Their destination: Palomar Mountain, site of the mighty Hale telescope, among others. There, using a smaller Schmidt telescope, they begin a seven-night stint of sentry duty...
...Shoemaker, with geologist Eleanor Helin, began the world's first systematic Earth-crossing-asteroid watch. When Helin left in 1982 to launch her own asteroid search, Carolyn, her three children grown, joined Gene. Since then they have been on the alert -- and on the run. Last fall, for example, they went to a conference in Ontario at the site of the 1.8 billion-year-old Sudbury Crater, which is 300 km (188 miles) wide. From there, they flew to Iowa City, Iowa, where Gene examined core samples from the nearby Manson Crater, 35 km (22 miles) across and about...
