This is toward the southern end of the San Andreas Fault, just east of the Salton Sea. It's 100 or more miles from San Diego, some 40 miles from Palm Springs, and much farther from the Land of LA. OTOH, it's 25-40 miles north of El Centro, Calexico, and the Mexican border. An earthquake in that area could be big in magnitude, but would not be very near big population centers.
