Brewer1 This report has not been reviewed for conformity with U.S. Geological Survey editorial stan­ dards and stratigraphic nomenclature. Description: The 1992 Landers earthquake occurred on June 28 with an epicenter near the town of Landers, California. [3] Only for the purpose of the application of any Deductible, any loss, destruction or damage to the Contract Works or other insured property arising during any one period of seventy two consecutive hours caused by water, flood, cyclone, storms, tempest, earthquake or bush fire shall be deemed to be a single event and therefore to constitute one occurrence. This earthquake was felt near Bakersfield and Sacramento, and at least 312 aftershocks were recorded. In the case of the Landers earthquake, about 95% of the aftershocks occurred within 5 km from the faults ruptured during the main shock [Liu et al., 2003]. Coulomb … The thin black rectangles illustrate the InSAR track footprints. Earthquake damage, the Landers and Big Bear earthquakes, June 28, 1992 by National Geophysical Data Center, unknown edition, Coseismic Coulomb stress changes induced by the Landers main shock computed at 10 km on right‐lateral receiver faults striking N340°E. Imprint Boulder, CO : National Oceanic and Atmospheric Administration, National Geophysical Data Center, [1993?] caused extensive damage throughout the area and hundreds of mostly minor injuries but minimal loss. The largest of these was the June 29, 1992, quake at Little Skull Mountain, likely triggered by the big (7.4) Landers earthquake in California. [2] The quake was described at the time as the largest earthquake to have occurred in the contiguous United States in 40 years. Available online At the library. Early on the morning of June 28, 1992, millions of people in southern California were awakened by the largest earthquake to occur in the western United States in the past 40 yrs. Earthquakes of 1992 in Landers and 1999 in Hector Mine broke faults at the surface, but didn’t do it at the main plate boundary, Biasi said. The coseismic stress perturbations due to the Landers earthquake are computed using a slip model derived from inversions of the InSAR and GPS data. Online. Calculations are performed for both homogeneous and transversely isotropic half‐space models. The faults involved are part of the Eastern California Shear Zone (ECSZ). Damage: Both earthquakes caused buildings to collapse, ignited fires, buckled roads, damaged water tanks and crippled water delivery systems, produced numerous rock slides in the San Bernardino Mountains, and derailed standing railroad boxcars near Barstow. At one point the road broke, rising three feet on one side. Earthquake damage, the Landers and Big Bear earthquakes, June 28, 1992 [slide]. Some 36 known faults run along and around Yucca … In Landers… The Big Bear Earthquake occurred on a previously unknown fault, which intersects the Camp Rock-Emerson fault. Surface ruptures associated with the 1992 Landers Earthquake, in San Bernardino County, extended for fifty miles with displacements ranging from one inch to twenty feet. Preliminary estimate of damage for this earthquake plus the following magnitude 6.5 event at 15:05 UTC is 92 million US dollars. This quake, which occurred at 4:58 AM, triggered the Big Bear Earthquake (M=6.5), at 8:05 AM on the same day. + guide (6 p. : map ; 28 cm.) ally the average damage in other build- ings induced by the mainshock in the Figure 3: The M 6.2 aftershock of the M 7.5 1992 Landers, California, earthquake The shock had a moment magnitude of 7.3 and a maximum Mercalli intensity of IX (Violent). The 1992 Landers earthquake occurred on June 28 with an epicenter near the town of Landers, California. Three hours later, another strong earthquake, magnitude 6.5, with its epicenter in the San Bernardino . This map compiles all discovered earthquake fault lines in California until 2010. At 4:57 a.m. local time (11:57 UTC) on June 28, 1992, a magnitude 7.3 earthquake awoke much of Southern California. Earth Sciences Library (Branner) Stacks Library has: 20 slides + 1 guide. We have been monitoring the healing of damage on the shallow Johnson Valley fault after its rupture in the 1992 magnitude-7.3 Landers earthquake, and here we report that this healing was interrupted in 1999 by the magnitude-7.1 Hector Mine earthquake rupture, which occurred 20-30km away. Damage to the shallow Landers fault from the nearby Hector Mine earthquake John E. Vidale, & Yong-Gang Li Published 2003, SCEC Contribution #1062 Crustal faults have long been identified as sites where localized sliding motion occurs during earthquakes, which allows for the relative motion between adjacent crustal blocks. 3.3 earthquake - 2.2 mi northeast of Westmorland, California, USA, on Sunday, 6 Dec 7:58 pm (GMT -8) - Minor magnitude 3.3 earthquake at 13 km depth Description: The 1992 Landers earthquake occurred on June 28 with an epicenter near the town of Landers, California.
