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. The stochastic models can be used to deduce ground motion from other earthquakes statistically similar to Imperial Valley. 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 … 4. surv./menlo park, ca/usa 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 The unreinforced brick wall at the Brawley Theater collapsed. Leeds, editor, 1980, 200 pp; OTHER REPORTS. 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. January 19, 1979 Strong earthquake Malibu, in Southern California. 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. 127701 W Old Inland Empire Hwy. The 1979 Imperial Valley Earthquake affected parts of southern California and Mexico. Our puppies have great temperaments and are great for big and small families. English: The 1979 Imperial Valley earthquake. Photo by C. Rojahn. If you live and vote in the Imperial Valley you have to see this! Several accelerograms were recorded in the vicinity of a steam power plant and near a tank farm where some tanks suffered structural damage. The origin time of the 1979 Imperial Valley earthquake is 23hr16min54.5sec with an epicenter of 32.63°N, 115.33°W, or approximately 5 km south of the … Imperial California Earthquake, October 1979 Page: Aerials | Ground | Close-ups | Other Earthquakes Imperial Fault trace 1 kilometer south of County Highway S-80 (11.3 kilometers northwest of the southeast end of the fault).

October 15, 1979 A 6.4 earthquake caused damage in Imperial Valley and Coachella. The main instrument used in the surveys is the 15, 1979, Imperial Valley earthquake. 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. The 1979 Imperial Valley Earthquake. It is 161% greater than the overall U.S. average. It happened at 16:16 Pacific time. 1979-10-15 23:16:53 UTC at 23:16 October 15, 1979 UTC Location: Epicenter at 32.667, -115.359 6.2 km from Islas Agrarias Grupo A … On 4/13/1949 at 19:55:42, a magnitude 7.0 (7.0 UK, Class: Major, Intensity: VIII - XII) earthquake occurred 181.1 miles away from Hermiston center, causing $80,000,000 total damage On 2/28/2001 at 18:54:32, a magnitude … Earthquake Information Chronological Earthquake Index Imperial Valley Earthquake. The Imperial Valley earthquake of 15 October 1979 offered a unique opportunity to advance the understanding of the behavior of unanchored oil storage tanks under strong motion earthquakes. Multiple aftershocks occurred after both, one as large as magnitude 5.5. Prosser, WA 99350. Strong-Motion Records from the Livermore Earthquakes of 24 and 26 January 1980: PR 28: Strong-Motion Records from the Mammoth Lakes Earthquakes of May 1980: PR 27: Compilation of Strong-Motion Records and Preliminary Data from the Imperial Valley Earthquake of 15 October 1979: PR 26 Earthquake of October 15, 1979, Imperial Valley, California. (2003). The trilateration network now comprises over 300 stations on an 800 in spacing square grid of agricultural roads, and extends to more than 20 km from the Imperial fault. Imperial Valley, 1892 Magnitude 7.3 The Feb. 24, 1892 earthquake near the California-Mexico border destroyed adobe buildings and … 6.4 magnitude earthquake. An event on the Imperial Fault Zone in the Imperial Valley. The locations … A Geological survey professional paper, "The Imperial Valley, California, Earthquake of October 15, 1979" softcover edition published in 1982 by the U.S. Government Printing Office. 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.
