...paper was later forced to publish an apology, even though tapes subsequently broadcast over Soviet television appeared to show Yeltsin at least mildly intoxicated. But Afanasyev's most serious failure was one that has also undone many an editor in the West: falling circulation. Over the past four years, as Soviet news buffs switched to livelier journalistic fare, Pravda's readership slipped from 10 million to 5 million...
...Afanasyev (no kin to Victor) -- every one a member of the Interregional Group A&F, which was founded by Starkov in 1978. It has grown to the astonishing circulation of 26 million, specializes in service features and has published other reader polls. It has thrived on controversy in the past, publishing glasnost-enlightened statistics on the number of Stalin's victims and the country's budget deficit, as well as admiring profiles of Western millionaires. But a poll that gave top ratings to Gorbachev's leading critics clearly had tested, and broken, glasnost's boundaries. It was hardly the type...
During the 1906 tremor, the plates on either side of the San Andreas lurched past each other by as much as 20 ft. Over time, such jumps add up. "In 30 million years," Berkeley seismologist Bruce Bolt says, "Los Angeles will become a new suburb of San Francisco...
...plates, restlessly roam about, driven by plumes of molten rock that roil up from the planet's superheated core. Many of the world's largest earthquakes occur at the boundaries of such plates. The San Andreas fault system divides the Pacific plate and the North American plate, which grind past each other at the pace of 2 in. a year. But this movement of the plates is not uniform. Along fault zones the plates tend to become "locked," resisting the overall motion. Explains Berkeley seismologist Robert Uhrhammer: "Stress builds up in these areas that are in effect welded shut...
Even though the mechanics of earthquakes are understood, accurate prediction of their occurrence has remained beyond reach. Earthquake forecasting is mostly based on past history. If a fault once generated a big earthquake, it can be assumed that it will do so again. But just where and when will the next big break occur? Here scientists are beginning to make headway. Geophysicist Wayne Thatcher of the USGS notes that the 1906 quake ruptured a 260-mile-long section of the San Andreas, extending from Cape Mendocino to San Juan Bautista. But the plate movement along the southern portion...
