To the west in the if the issue persists. This quake, which occurred at 4:58 AM, triggered the Big Bear Earthquake (M=6.5), at 8:05 AM on the same day. At one point the road broke, rising three feet on one side. That event caused at least 78 fatalities and 250 injuries in Oaxaca, and a further 16 deaths in Chiapas. 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 What is Your Earthquake Risk? 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. 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. The thin black rectangles illustrate the InSAR track footprints. Details . At 4:57 a.m. local time (11:57 UTC) on June 28, 1992, a magnitude 7.3 earthquake awoke much of Southern California. 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]. It was preceded by the 6.1 Joshua Tree quake on April 22, and followed 3 … The fault has since resumed the trend of strength recovery that it showed after the Landers earthquake. It caused considerable structural damage to the surrounding area, and one death - a three-year-old child. The shock had a moment magnitude of 7.3 and a maximum Mercalli intensity of IX (Violent). In Landers… Earthquake damage, the Landers and Big Bear earthquakes, June 28, 1992 by National Geophysical Data Center, unknown edition, 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 early quake caused heavy damage to Old Woman Springs Road, a major route north of Yucca Valley to Landers. The entire wiki with photo and video galleries for each article Some 36 known faults run along and around Yucca … One person was killed at Yucca Valley, two people died of heart attacks, more than 400 people were injured and substantial damage occurred in the Landers - Yucca Valley area. Figure 9. 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.

The Landers earthquake surface rupture is plotted in red. The coseismic stress perturbations due to the Landers earthquake are computed using a slip model derived from inversions of the InSAR and GPS data. of life. Description: The 1992 Landers earthquake occurred on June 28 with an epicenter near the town of Landers, California. The Morongo Basin Historical Society is located in Landers… The earthquake. It was located on the Camp Rock-Emerson Fault. The Big Bear Earthquake a little over three hours later, and a lot less powerful than the Landers' event, was in a more populated area, and thus more damage was caused despite it only being a moderate-size earthquake. Santa Barbara . At 4:57 a.m. local time (11:57 UTC) on June 28, 1992, a magnitude 7.3 earthquake awoke much of Southern California. Loma Prieta earthquake which caused major damage to the San Francisco Bay Area measured 7.1 in magnitude.) Imprint Boulder, CO : National Oceanic and Atmospheric Administration, National Geophysical Data Center, [1993?] The Landers Earthquake (M=7.4) was the strongest earthquake to strike California since 1952. Open in figure viewer PowerPoint. The earthquake did no damage at Yucca Mountain, which is 240 miles northeast of the epicenter. The shock had a moment magnitude of 7.3 and a maximum Mercalli intensity of IX (Violent). Preliminary estimate of damage for this earthquake plus the following magnitude 6.5 event at 15:05 UTC is 92 million US dollars. Landers & Big Bear . The Northridge Earthquake vividly showed that it only takes a moderate-sized earthquake in an urban area to cause major damage. 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. So, even though an earthquake may be quite … Earthquakes: 1987 Whittier Narrows, 1989 Loma Prieta, 1994 Northridge, 1992 Landers, 2014 South Napa. The 1992 earthquake at Landers was a magnitude 7.6--the largest to have struck California in 40 years. The 1992 Landers Earthquake was a magnitude 7.3 earthquake that occurred on June 28, 1992 with an epicenter near the town of Landers, California. Coulomb … The Big Bear Earthquake occurred on a previously unknown fault, which intersects the Camp Rock-Emerson fault. 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. Maximum intensity IX. The Hector Mine earthquake both strongly shook and permanently strained the Johnson Valley fault, adding damage discernible as a temporary reversal of the healing process. Earthquake damage, the Landers and Big Bear earthquakes, June 28, 1992 [slide]. [2] The quake was described at the time as the largest earthquake to have occurred in the contiguous United States in 40 years. The Landers and Big Bear earthquakes had been. caused extensive damage throughout the area and hundreds of mostly minor injuries but minimal loss. + guide (6 p. : map ; 28 cm.) National Earthquake Information Center U.S. Geological Survey Denver, Colorado. At 4:58 a.m PDT (local time), faulting associated with the magnitude 7.3 earthquake broke through to earth's surface near the town of Landers, California. It was followed later that morning by a magnitude 6.7 quake at Big Bear. The Preliminary Damage and Intensity Survey for the Landers, California, Earthquake of June 28,1992 Open-File Report 93-191 by Lindie R. Brewer1 This report has not been reviewed for conformity with U.S. Geological Survey editorial stan dards and stratigraphic nomenclature. The area was the epicenter of the June 28, 1992 Landers earthquake, a magnitude 7.4 strike-slip earthquake. The hypocenter of the September 8th, 2017, M 8.2 earthquake offshore Chiapas is located 240 km southeast of today's earthquake. This earthquake was felt near Bakersfield and Sacramento, and at least 312 aftershocks were recorded. Online. The faults involved are part of the Eastern California Shear Zone (ECSZ). 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.
