From the stations of the World-Wide Standard Seismograph Network and Canadian Seismic Network, estimates of the duration of far-field long-period SH waves were made by computing the variance or … On October 15, 1979, the largest earthquake in California in the last quarter century occurred on the imperial fault near the international boundary between the United States and Mexico. One of four damaged reinforced-concrete columns along the east end of the Imperial County Services Building between the ground and second floors. The 1979 Imperial Valley earthquake triggered all of the accelerographs within about 100 km of the epicenter, and one as far away as 196 km. 6.4 magnitude earthquake. At this time (280CT79) information is not available on all of the stations beyond 150 km. Leeds, editor, 1980, 200 pp; OTHER REPORTS. - 4 - • The final model, for which point source responses are calculated by a discrete wavenumber/finite element technique, uses a structure with gradients in material properties rather than layers.

Multiple aftershocks occurred after both, one as large as magnitude 5.5. During the 1979 Imperial Valley earthquake, an array of 26 strong‐motion accelerometers produced records for the Meloland Road Overpass, a two‐span reinforced concrete bridge structure located only 0.5 km away from the causative fault for this earthquake event. Earthquake Information Chronological Earthquake Index Imperial Valley Earthquake. Imperial Valley, 1892 Magnitude 7.3 The Feb. 24, 1892 earthquake near the California-Mexico border destroyed adobe buildings and … TYPE OF FAULTING: right-lateral strike-slip TIME: October 15, 1979 / 4:54 pm PDT LOCATION: 32° 37' N, 115° 19' W about 29 km (18 miles) southeast of El Centro By comparing synthetic particle velocities with the near‐source strong motion data we have constructed, by trial and error, a faulting model for the 1979 Imperial Valley earthquake. (2003). A new method for estimating source extent parameters has been applied to the Imperial Valley earthquake of October 15, 1979, and the Victoria earthquake of June 9, 1980. Unlike the twoexamples discussed above, though, this case does not support a charac-teristic-slip model.

Most of the building damage in the business district of Brawley occurred between the 500 and 900 blocks. Twelve three-component strong-motion displacement records are modeled for the 1979 Imperial Valley earthquake to recover the distribution of slip on the Imperial fault plane. 4. The 1979 Imperial Valley earthquake can be characterized as a magnitude 5 earthquake at the hypocenter which then grew into or triggered a magnitude 6 earthquake north of the border.
