A magnitude 4.9 earthquake centered on the San Jacinto fault 10 miles north of the desert town of Borrego Springs rattled a wide swath of Southern California Friday night, but caused no damage or injuries. The 8:14 p.m. quake was felt in San Diego, Orange, Riverside, San Bernardino and Los Angeles counties.

A magnitude 4.2 earthquake near the intersection of the San Andreas and San Jacinto faults hit an area four miles northwest of San Bernardino on Saturday afternoon, and quake scientists declared a low-level precautionary alert. No damage was reported in the 2:45 p.m. temblor, which was followed by several light aftershocks. It was felt in San Bernardino, Colton, Rialto and the San Bernardino Mountain resorts, the San Bernardino County sheriff's office said.

A cluster of magnitude-3 and -4 earthquakes along the San Jacinto Fault, which runs from the San Bernardino area southeast to the Mexico border, has local seismologists wondering if a much larger quake may be approaching. But although the pattern is unusual, they add, they are not making outright predictions of a major jolt any time soon and see little cause for alarm.

A mild earthquake on Southern California's most active fault rattled desert dwellers but apparently caused no damage or injuries. The jolt measured magnitude 3.3 and was centered 15 miles south of Palm Desert on the San Jacinto Fault Zone, said Robert Finn, spokesman for Caltech's seismological laboratory in Pasadena. A recent report by Caltech and the U.S. Geological Survey said the fault "produces the greatest number of small earthquakes of all the faults in Southern California."

An Arizona seismologist reports a 130- to 150-year link among strong earthquakes in Southern California, saying that the great 1857 Ft. Tejon temblor on the San Andreas Fault may have sent a pulse of underground strain moving about a mile a year and triggering eight successive quakes along the San Jacinto Fault. Writing in today's issue of Science, Christopher O. Sanders of Arizona State University says the latest quake in the series was a magnitude 6.

Earthquakes of the last two months in Southern California, including a 5.1-magnitude quake centered in Riverside County late Tuesday night, may mark the end of a period of seismic quiescence that followed the 1992 Landers and 1994 Northridge earthquakes, scientists said Wednesday. Tuesday's quake was centered near the town of Anza, 21 miles south of Palm Springs, at 11:56 p.m. and was followed by scores of small aftershocks. Caltech and U.S.
