Small earthquakes rattled eastern San Diego County on Thursday afternoon.
U.S. Geological Survey geophysicist Dale Grant said a magnitude-3.4 temblor hit at 2:45 p.m. about five miles north of Julian. It was felt as far away as San Diego and in suburbs of Santee and El Cajon.
About an hour earlier, a magnitude-3.0 quake hit about 15 miles northeast near Borrego Springs.
A number of much smaller tremors preceded and followed those quakes.
Seismologist Kate Hutton of the California Institute of Technology says the quakes seems too distant to be related to a swarm of seismic activity about 50 miles east in the Salton Sea region, but seismologists don't know for sure.
