Another small earthquake tipping magnitude 3.0 jiggled rural Southern California Sunday morning, seismologists said. The magnitude 3.8 shaker was recorded 18 miles from Barstow around dawn, following up a 3.2 quake that struck in the same area three days ago. The U.S. Geological Survey said the quake occurred at a shallow depth of roughly 1 mile. The Los Angeles Times had no immediate reports of damage or injuries in the sparsely populated desert area.e t
