The rupture then bent abruptly southward onto the Canon Rojo normal fault, where slip was almost perfectly dip slip (Mueller & Rockwell, 1991, 1995). The 2010 Baja California earthquake (also known as 2010 Easter earthquake, 2010 Sierra El Mayor earthquake, or 2010 El Mayor – Cucapah earthquake) occurred on April 4 (Easter Sunday) with a moment magnitude of 7.2 and a maximum Mercalli intensity of VII (Very strong).wikipedia These were combined in a network adjustment to produce 1 Hz total displacement waveforms over the entire network (waveforms, plots), a movie of 1 Hz displacements, and rapid coseismic horizontal displacements (values, map). The epicenter was approximately 47 km The shock originated at 15:40:41 loc [View full scale image]. Two people killed and at least 233 injured in the Mexicali area. Long baseline strainmeter plots: these instruments are called ‘‘longbase’’ sensors because they produce high-quality data by measuring strain over distances of hundreds of meters at the surface of the Earth. The colorful swaths on the main map show before-and-after changes, with each color representing a few inches of movement. This is an area with a high level of historical seismicity, though this is the largest event to strike in this area since 1892. The active Laguna Salada Fault ruptured in February 1892 with an estimated Mw 7.2 earthquake. The epicenter is about 60 km south of Mexicali. It was felt Learning from Earthquakes The Mw 7.2 El Mayor Cucapah (Baja California) Earthquake of April 4, 2010 throughout Baja California, Southern California, Arizona, and Nevada. Produced by Wade Johnson at UNAVCO. Distance from the event increases as you move upward. 20 km 2 (=8 sqare miles) as a first-order estimate. De tekst is beschikbaar onder de licentie. The group also observed liquefaction-related features along canal-levees, widespread shattering along levee crusts, and minor flooding, ground failure or cracking, and sand blows. Aftershocks of the 5.3 quake Baja California, Mexico, 2010-09-15 07:50 UTC More info Based on its magnitude, the fault that was active during the quake ruptured along a surface of approx. Figure 10 - Map showing fault slip rates with an overlay of the main shock and 12 hours of aftershocks, with yellow lines (<0.2), pumpkin (0.2-1), orange (1.5) and red (>5 mm/yr) lines (Ramon Arrowsmith at Arizona State University). More information on the main shock is available here. Earthquake Summary Poster. The earthquake has been named the El Mayor-Cucapah earthquake. A powerful earthquake swayed high-rises in San Diego County and was felt across Southern California and Arizona on Sunday afternoon. The quake was the largest in the Baja California and Southern California area since 1992, the USGS reported. CEA’s CEO, Glenn Pomeroy, looks back at the damage caused by the Baja California Earthquake in 2010. Surface rupture and slip variation induced by the 2010 El Mayor – Cucapah earthquake, Baja California, quantified using COSI-Corr analysis on pre- and post-earthquake LiDAR acquisitions 1999.
