The topography surrounding the Laguna Salada Fault in the Mexican state of Baja, California, is shown in this combined radar image and topographic view with data from NASA Shuttle Radar Topography Mission where a 7.2 earthquake struck on April 4, 2010.īaja Earthquake, Radar Image and Colored Height When we compare one month of seismicity before and after the M9.0 earthquake, the preliminary analysis shows absence of triggered seismicity in the northern Peninsular Ranges and an increase of seismicity south of the Mexicali valley where the Imperial fault jumps southwest and the Cerro Prieto fault continues. We use the seismic catalog of RESNOM to search for changes in local seismic rates occurred after the passing of surface waves generated by the Tohoku-Oki, Japan earthquake. This network consists of 13 three-component seismic stations. The seismicity in these regions is monitored by the seismic network RESNOM operated by the Centro de Investigación CientÃfica y de Educación Superior de Ensenada (CICESE). In the eastern region of Baja California shearing between the Pacific and the North American plates takes place and the Imperial and Cerro-Prieto faults generate most of the seismicity. These Peninsular Ranges of Baja California exhibits high microseismic activity and moderate size earthquakes. The northwestern area of Baja California is characterized by a mountain range composed of crystalline rocks. We analyze possible variations of seismicity in the northern Baja California due to the passage of seismic waves from the 2011, M9.0, Tohoku-Oki, Japan earthquake. Preliminary Analysis of Remote Triggered Seismicity in Northern Baja California Generated by the 2011, Tohoku-Oki, Japan Earthquake This image from NASA Terra spacecraft shows where a magnitude 7.2 earthquake struck in Mexico Baja, California at shallow depth along the principal plate boundary between the North American and Pacific plates on April 4, 2010.
