A magnitude of 4.1 earthquake has hit the California border area, about 53 kilometers south of Mexicali. The U.S. Geological Survey reported on Sunday that there was no immediate report of injuries and property damage. The area has been hit by a series of small temblors after a 7.2- magnitude “Easter” earthquake struck on April 4th, killing two people in Mexico and causing more than 90 million dollars in damage.
