Scientists say the long-awaited Parkfield earthquake should hit Central California sometime within the next two years, most likely around March, 1991. Parkfield, which straddles the San Andreas Fault east of San Luis Obispo, has had moderate quakes about every 22 years, and the area has been heavily instrumented by scientists who hope to learn much about what happens before, during and after a temblor. The last quake hit in 1966. The quakes usually have a magnitude of about 5.

The director of the state Office of Emergency Services said Thursday that even if no earthquake shakes the hamlet of Parkfield, this week's prediction experiment was overwhelmingly positive and in similar circumstances such an alert would be issued again. On Monday night, after a magnitude 4.7 earthquake struck near Parkfield in Monterey County, the state and the U.S.

After last week's false alarm, Parkfield is rumbling again, and scientists say there is a renewed--but smaller--chance that a long-predicted magnitude 6 earthquake will strike soon along a much-monitored portion of the San Andreas Fault. The U.S. Geological Survey issued a Level B alert early Monday, after six small earthquakes rattled Middle Mountain, just northwest of the Central California ranching town. The largest, a magnitude 3.9, struck at 11:27 p.m. Sunday.

In 1985, the U.S. Geological Survey issued what it calls "the first officially accepted earthquake prediction in the United States." The prediction said an earthquake registering 6.0 on the Richter scale is expected to occur along the San Andreas Fault near the Monterey County town of Parkfield before 1993. An earthquake of a similar magnitude has occurred in that area about every 22 years, the U.S. Geological Survey said.

The site of one of scientists' most important earthquake prediction experiments, in Parkfield, Calif., was rattled by a magnitude 4.0 temblor Friday. No damage or injuries were reported from the moderate quake, which struck at 7:26 a.m. It was centered 6.6 miles deep and five miles northwest of the sparsely populated hamlet in southeastern Monterey County. No aftershocks were detected.

At the Parkfield Cafe in this tiny ranch town tucked inside the Coast Range, scientists and reporters huddle like a pack of expectant fathers. Townsfolk eye them warily. Never have so many strangers gathered in such a small spot to wait for--even root for--the earth to shake. They started to overrun this hamlet on the San Andreas Fault at midnight Monday, shortly after a 4.
