Moderate quake hits U.S. border
A 4.4 magnitude earthquake hit the U.S. border in the Imperial Valley, Southern California early Saturday, shaking people awake in the region.
People in San Diego, Orange and Santa Ana counties felt the quake, which occured at 2:12 a.m. and was centered 16 miles (about 16 kilometers) west southwest of Calexico bordering Mexico, according to the U.S. Geological Survey (USGS).
Hundreds of earthquakes in the magnitude 2.0 range, as well as a few above 3.0, have hit along the Laguna Salada Fault at the U.S. -Mexican border, the USGS said.
The quakes are generally hitting northwest of the epicenter of last Sunday's magnitude 7.2 earthquake,which killed two people in Mexicali, Mexico and caused more than 100 million dollars in damage in California.
