Fault-zone waves observed at the southern Joshua Tree earthquake rupture zone Fault-zone waves observed at the southern Joshua Tree earthquake rupture zone
Waveform and spectral characteristics of several aftershocks of the M 6.1 22 April 1992 Joshua Tree earthquake recorded at stations just north of the Indio Hills in the Coachella Valley can be interpreted in terms of waves propagating within narrow, low-velocity, high-attenuation, vertical zones. Evidence for our interpretation consists of: (1) emergent P arrivals prior to and opposite...

Southern surface rupture associated with the M 7.3 1992 Landers, California, earthquake Southern surface rupture associated with the M 7.3 1992 Landers, California, earthquake
Although most evidence suggests that the 28 June 1992 M 7.3 Landers earthquake ruptured unilaterally north, significant surface rupture was mapped on the Eureka Peak and Burnt Mountain faults, to the south of the Landers epicenter. An eyewitness account reports that surface rupture occurred on the northern Eureka Peak fault within approximately 35 sec of the mainshock initiation. Array...

The Loma Prieta, California, Earthquake of October 17, 1989: Strong ground motion The Loma Prieta, California, Earthquake of October 17, 1989: Strong ground motion
Strong ground motion generated by the Loma Prieta, Calif., earthquake (MS~7.1) of October 17, 1989, resulted in at least 63 deaths, more than 3,757 injuries, and damage estimated to exceed $5.9 billion. Strong ground motion severely damaged critical lifelines (freeway overpasses, bridges, and pipelines), caused severe damage to poorly constructed buildings, and induced a significant...

Southern surface rupture associated with the 1992 M7.4 Landers Earthquake: Did it all happen during the mainshock? Southern surface rupture associated with the 1992 M7.4 Landers Earthquake: Did it all happen during the mainshock?
Approximately three minutes after the magnitude 7.4 Landers mainshock on 28 June 1992, a M5.7 aftershock occurred south of the mainshock epicenter, with a location of 34° 7.65′N, 116° 23.82′W. This aftershock was recorded on an array of portable digital seismic instruments deployed in Morongo Valley, 21 km southwest of the event. Although peak accelerations are found to differ by...

Sediment-induced amplification and the collapse of the Nimitz Freeway Sediment-induced amplification and the collapse of the Nimitz Freeway
The amplification of ground motion by low-seismic-velocity surface sediments is an important factor in determining the seismic hazard specific to a given site. The Ms = 7.1 Loma Prieta earthquake of 17 October 1989 was the largest event in the contiguous United States in 37 years, and yielded an unparalleled volume of seismic data from the main shock and aftershock sequence1. These data...
