    A moderate-magnitude earthquake (M L = , California Institute of Technology, Seismological Laboratory) occurred at (PDT) on 15 October , approximately km east-southeast of Calexico, California (location map - page 2). The main shock, a shallow focus event centered in Baja, California, was located at °N latitude and °W longitude (CIT, Seismological Laboratory). The unit's structural and mechanical systems sustained only minor damage during the Octo Imperial Valley earthquake that produced an estimated g peak horizontal ground acceleration ( g vertical) at the site.

    The largest earthquake in Imperial: today: in Salton City, California, United States. this week: in Salton City, California, United States. this month: in Salton City, California, United States. this year: in Ridgecrest, California, United States. Sorted: Recent. The above table from to is based on "California Earthquake History present", which is a list put together by the United States Geological Survey (USGS).Updates on recent earthquakes from to the present are based on entries in magnitudes that the USGS gives for earthquakes after are similar to the famous Richter scale, in which the magnitude, more or less.

    On Octo an earthquake of local magnitude was triggered on the Imperial Fault. The epicenter was located 5 kms south of the U.S.-Mexico border. The Imperial Fault has been seismically active for years. The last major event was the El Centro Earthquake. EARTHQUAKES STRIKE IMPERIAL VALLEY IN "SUPERSTITION HILLS SEQUENCE" November , A magnitude (M) earthquake jolted th Imperial Valley on Novem at a.m., just 12 hours after a M temblor struck the same area. The quake was the strongest in California since the Central Valley's M Coalinga earthquake of May 2,
