A moderate earthquake rattled mountain communities in northeastern San Diego county Wednesday.

The quake hit shortly before 11 a.m., according to the U.S. Geological Survey. It was centered about seven miles northeast of Julian, 34 miles east of Escondido and 45 miles northeast of downtown San Diego.

It was "just a real sharp jolt ... real quick,'' said Charlie Molinari, owner the Apple Tree Inn on state Route 78 in Julian. "It scared my cat, but that was about it,."

Firefighters at the Julian Fire Department said that they felt the temblor, but they received no reports of damage or injuries. Other public safety agencies, including the county Sheriff's Department and Cal Fire, received no reports of any problems caused by the shaker.

"We did feel it here at (El Cajon) City Hall -- a quick jolt and that was it,'' said Monica Zech, a spokeswoman for the city. "I got one call from someone in the Alpine area who said it sounded like an explosion ... and was concerned.''
