4th quake, magnitude 3.6, strikes San Diego County

SCISSORS CROSSING, Calif. (KABC) -- A 3.6-magnitude earthquake struck an area about 20 miles east, northeast of San Diego early Thursday morning, making it the fourth to hit the area in less than 24 hours.

The temblor struck a little more than 3 miles north of Scissors Crossing, which is about 20 miles from San Diego County Estates, according to the U.S. Geological Survey. It struck at 2:32 a.m. and was about 6 miles deep.

The earthquake comes hours after a 3.8 struck in the same area just shortly before 8 p.m. That quake followed a 3.0 aftershock from a 4.0-magnitude earthquake that hit Julian, California, Wednesday afternoon.

All four of these earthquakes registered on ABC7's Quake Cam. There was no immediate word of any injuries or damage from these quakes.
