Epicenter and Geological Context
The earthquake’s epicenter was located just a few miles from Julian, a town renowned for its apple pie shops. The quake originated at a depth of 8.3 miles (13.4 kilometers) near the Elsinore fault zone, which is part of the larger San Andreas fault system . This region is known for its seismic activity, with the Elsinore fault being one of the most active in Southern California.
Impact and Immediate Response
Despite the moderate magnitude, the earthquake caused noticeable shaking across Southern California. In Julian, local businesses experienced minor disruptions. For instance, at the Eagle Mining Co., some picture frames fell over, but the historic mine tunnels remained undamaged. Similarly, the Julian Cafe & Bakery reported a few cups falling but no significant damage .
