Southern Californians were rattled on Monday morning when a strong earthquake shook the areas around San Diego just after 10am local time.
Initial measurements from the United States Geological Survey rated the temblor as a magnitude 5.2, with an epicenter in Julian, a mountain town in San Diego county with roughly 2,000 residents known for its apple pie, located roughly 35 miles north-east of San Diego and 120 miles south of Los Angeles.
