Dozens of earthquakes in Southern California are not directly related to major earthquakes, experts say (Alberta Times) According to monitoring data from the United States Geological Survey, as of the afternoon of August 26, more than 70 earthquakes occurred in the Brawley area of Southern California, including three earthquakes of magnitude 5 or above and multiple earthquakes of magnitude 4 or above. The strongest earthquake detected that day in the Brawley area of ​​southern California, located on the border between the United States and Mexico, was 5.5 magnitude. Since 10:02 a.m., dozens of earthquakes have occurred in the area. The strongest one, with a magnitude of 5.5, occurred at 13:57 local time. Because the earthquake ranged from several kilometers to more than 10 kilometers underground, it was a shallow earthquake and could be felt in nearby San Diego, Orange County and most parts of Arizona. Dr. Chu Risheng from the California Institute of Technology’s Institute of Seismology said that the area on the border between the United States and Mexico is an earthquake-prone area, with large felt earthquakes occurring every year. The continuous earthquakes should be a combination of foreshocks, mainshocks and aftershocks, which is a normal phenomenon. Dr. Chu Risheng believes that these earthquakes are not directly related to the major earthquake of magnitude 7 or above that people say will occur in California.
