Published 12:05 a.m. PDT Tuesday, August 20, 2002 LOS ANGELES (AP) - When the Earth started shaking in Fiji, people and computers thousands of miles away in quake-sensitive Southern California took notice.
The result, a 7.7-magnitude quake centered in the South Pacific was recorded as temblors of magnitude-3.0 or higher Monday morning in the Southern California cities of Bakersfield, Palm Springs and San Bernardino.
The quake had sent such a powerful shock wave across the Pacific that it was automatically recorded on a network of about 300 Southern California seismic monitors, said Kate Hutton, a seismologist with the California Institute of Technology.
The results, recorded at 4:12 .a.m., were automatically posted on a Web site used by both journalists and scientists, where they remained for about four hours.
Seismologists, who can tell the difference between local and foreign temblors by the patterns they make on computerized recordings, realized the error when they came to work, Hutton said.
The monitors often record foreign quakes but they don't usually trigger the automatic program, she added.
There were no immediate reports of any damage or casualties from the quake near Fiji, which was very deep in the Earth's crust.
