Each station consists ofĪ broadband seismometer and a strong-motion instrument in order toĮnsure that the full range of ground motions are recorded on scale. Today the BDSN consists of 28īroadband stations with 24-bit digitizers. The difficulties experienced in 1989 were motivation for theĭigital Seismic Network in 1991. Order to locate the earthquake, but it was not possible to use the The data were useful for providing P-wave travel times in Some of the seismometers displayed non-linear effects from the strong Of the 16-bit systems, all of these instruments "clipped". Seismological Laboratory operated a small network of 16-bit digital seismometers. Realtime earthquake map of the South BayĪt the time of the Loma Prieta earthquake, the Berkeley.Monthly and annual seismicity for the Loma Prieta region.Background seismicity for the Loma Prieta region.One month of seismicity following the Loma Prieta mainshock.This earthquake has been extremely well-studied and numerous 100 km ( 62 miles) SSE ( 159 degrees) of Berkeley, CA.95 km ( 59 miles) SSE ( 150 degrees) of San Francisco, CA.91 km ( 57 miles) SSE ( 158 degrees) of Oakland, CA.71 km ( 44 miles) S ( 188 degrees) of Livermore, CA.47 km ( 29 miles) N ( 5 degrees) of Monterey, CA.34 km ( 21 miles) S ( 177 degrees) of San Jose, CA.22 km ( 13 miles) WSW ( 244 degrees) of Morgan Hill, CA.16 km ( 10 miles) ENE ( 61 degrees) of Santa Cruz, CA. The most costly natural disaster in the United States.īecause of its proximity to the San Francisco Bay Area, the earthquake Consequently, the potential for a damagingĮarthquake on the San Andreas in the Santa Cruz mountains may still exist. That the earthquake occurred on a sub-parallel fault and not on the This type of motion is not typical of the San Andreas fault and suggests Was 1.2 meters while the average reverse-slip displacement was 1.6 meters. Km of the 1906 break, in comparable amounts of right-lateral strike The Loma Prieta earthquake ruptured the southernmost 40 To occur along the San Andreas fault zone since theĮarthquake.
