1892 laguna salada earthquake

The magnitude 7.2 earthquake that jolted northern Mexico and Southern California yesterday afternoon was the first big earthquake to occur on this particular fault system since 1892, scientists say. El terremoto de 1892 Laguna Salada se produjo a las 23:20 hora estándar del Pacífico el 23 de febrero.Tenía un estimado de la magnitud del momento de 7,1-7,2 y una intensidad máxima percibida de VIII ( severa).El choque fue centrado cerca de la frontera entre México y Estados Unidos, y toma su nombre de un gran lago seco en Baja California, México. The 1892 Vacaville–Winters earthquakes occurred in northern California as a large doublet on April 19 and April 21. In 1956 a magnitide-6.8 earthquake originated on the San Miguel-Vallecitos fault. It had an estimated moment magnitude of 7.1–7.2 and a maximum perceived intensity of VIII . The earthquake was the result of a rupture along the Imperial Fault, with its epicenter 5 miles (8.0 km) north of Calexico, California. Comprehensive reports on the earth- The Laguna Salada Fault is thought to be the origin of the 2010 Baja California earthquake. 4). Geology. According to some compilations, the Laguna Salada, Baja California, earthquake of 23 February 1892 ranks among the largest earthquakes in … By Susan E. Hough and Austin Elliot. The western margin of the Sierra Cucapah is defined by the Laguna Salada fault (LSF), which forms part of an active west-directed oblique detachment system recognized as the source of the large (M7+) February 22, 1892 earthquake. It produced a complex rupture that left the Laguna Salada fault, which was almost perfectly oblique, with striations and offsets indicating ~45 degree rake, parallel to the intersection of the two faults that were activated. The Laguna Salada Fault zone is about 70 km in length and slips at an estimated rate of 4 mm/yr. Stress at the hypocenter of the 1968 Borrego Mountain earthquake was increased by the 1812 Wrightwood, 1857 Fort Tejon, 1892 Laguna Salada and 1940 Imperial Valley quakes. But the region where Sunday’s quake occurred has been seismically active for the past year, and there were several foreshocks that occurred, beginning last Wednesday, with magnitudes between 3 and 4, Jones said. The shock was centered near the Mexico–United States border and takes its name from a large dry lake bed in Baja California, Mexico. 1892.02.24 32.55 –115.65 7.3 Laguna Salada, Baja California Damage San Diego to Imperial Valley 1892.04.19 38.40 –122.00 6.6 Vacaville 1 death, $225 000 loss 1898.03.31 38.20 –122.50 6.4 Mare Island $350 000 loss 1898.04.15 39.20 –123.80 ~ 6.7 Fort Bragg - … The Laguna Salada fault had an earthquake of similar size in 1892 (Hough and Elliot, 2004 BSSA). Revisiting the 23 February 1892 Laguna Salada Earthquake . In 1892 a magnitide-7-7.5 earthquake occurred on the Laguna Salada Fault. The 1892 earthquake occurred along the Laguna Salada fault system, but surface offsets associated with the 1892 event lie farther northwest than the April 4th mainshock’s epicenter. Tuesday's earthquake, a 5.4, fell below the 200 biggest California quakes on record. Results of the mapping suggest the earthquake in 1892 ruptured a segmented set of faults, separated by seismic gaps. The 1892 Laguna Salada earthquake occurred at 23:20 Pacific Standard Time on February 23. [c6, p159] The strong earthquake of February 24, 1892, located near the United States-Mexican border was assigned to the Agua Caliente fault north of the border by Toppozada and others (1981) and to the Laguna Salada fault in Baja California by Strand (1980). The 1892 earthquake is a reasonable choice for the source of the scarps along the Laguna Salada fault, not only because of the damage pattern interpreted from historical in- The fact that the area was largely uninhabited helped to minimize damage and meant that there were no fatalities. surface ruptures from the 2010 El Mayor-Cucapah and 1892 Laguna Salada earthquakes, ... EMC earthquake also did not occur on any of the dominant fault strands at this latitude of the plate margin (eg., Imperial, Cerro Prieto, Laguna Salada, and Cañada David faults; Fig. Download PDF (190 KB) Abstract. State boundaries areoutlinedin gray. Objectives of this project were to map and measure surface displacement in the Mw 7.2 1892 Laguna Salada earthquake and to compare the strain field with the Mw 7.2 2010 El Mayor-Cucapah earthquake. Although surface rupture was not documented at the time of the earthquake, recent geologic investigations have identified and mapped a rupture on the Laguna Salada fault that can be associated with high probability with the 1892 event (Mueller and Rockwell, 1995). The 1892 earthquake occurred along the Laguna Salada fault system, but surface offsets associated with the 1892 event lie farther northwest than the 4 April 2010 mainshock's epicenter.
