Near-field high resolution strain measurements prior to the October 18, 1989, Loma Prieta Ms 7.1 earthquake, Geophys. Res. Lett. 17, 1777-1780.Johnston, M.J.S., Linde, A.T., Gladwin, M.T., 1990. Near-field high resolution strain measurements prior to the October 18, 1989, Loma ...
Postseismic deformation along a 90-km profile bisecting the projected surface trace of the coseismic rupture of the 1989 Loma Prieta earthquake has been monitored by frequent GPS surveys for 3.3 years following the earthquake. In addition to the expected deformation associated with secular strain ...
We have used 24 broadband teleseismic and 48 components of local strong-motion velocity records of the 1989 Loma Prieta earthquake in a formal inversion to... DJ Wald,DV Helmberger,TH Heaton - 《Bulletin of the Seismological Society of America》 被引量: 310发表: 1991年 Postseismic strain foll...
Thirty six strain gages are attached to two segments of welded steel pipe to measure length changes and flexure. Twelve displacement transducers are installed in jointed ductile iron pipe to measure rotation and extension at the joints. Ground motion records from the Loma Prieta Earthquake of Oct....

These analyses show that the stress, strain and force distributions were so unfavorable as to cause the "pre-Northridge" connection to fail due to low cycle fatigue. Results of cyclic cantilever beam-to-column connection tests are used herein to evaluate both the fracture modes and the ...
Real values of the cumulative Benioff strain release surpass the expected modeled ones, indicating, that large aftershocks cluster at the beginning of the Loma Prieta sequence immediately after the occurrence of the main shock. Strain release spatial analysis reveals release patterns, which change ...
We inverted aftershock focal mechanisms of the 1989 Loma Prieta earthquake for the orientations of the principal instantaneous strain axes, their relative magnitude, and the relative vorticity parameter for each of 17 spatially clustered sets subdivided into 33 subsets each of which accommodates a ...
The topography of the northern Santa Cruz Mountains in the vicinity of the San Andreas fault is consistent with the vertical strain field and the inferred recurrence interval of the 1989 Loma Prieta earthquake, with the long-term slip rate on the San Andreas, and with the rates at which the...
