The 89-second quake was widely felt throughout northwest Mexico and southern California. It was also the strongest to rock southern California in at least 18 years (since the M 7.3 1992 Landers earthquake), if not longer: the next most recent comparable earthquake—the 1952 Kern County earthquake (M 7.3)—was 58 years earlier. Each of these earthquakes had a similar magnitude, and was also felt across a large swath of North America. Most of the damage occurred in the twin cities of Mexicali and Calexico on the Mexico–United States border.
