A magnitude 5.1 earthquake jolted southern Mexico early Saturday after a smaller temblor was recorded in northern California, U.S. seismologists reported. The U.S. Geological Survey said the Mexican quake struck shortly after dawn in the Oaxaca region of Mexico, about 7 miles southeast of San Pedro Amuzgos. There were no immediate reports of damage or injury. Southern Mexico and Central America have been experiencing a number of quakes in recent days. Most have been relatively minor but at least three have reached magnitude 5.4. Northern California has also been seismically busy. The Santa Rosa area experienced a 3.3 magnitude quake around 1:23 a.m. PDT Saturday. The Los Angeles Times said it was the second quake topping 3.0 centered in the area in the last 10 days.
