Yes, that was an earthquake you felt this morning. There was a 4.7 quake in El Cerrito, near the City of Corona, at 10:29 a.m., according to the Southern California Seismic Network. See the map below for the exact location.

Take a look at the graphic below. It depicts the “Ring of Fire.”
“The Ring of Fire is a zone of frequent earthquakes and volcanic eruptions that encircles the basin of the Pacific Ocean. It is shaped like a horseshoe and it is 40,000 km long. It is associated with a nearly continuous series of oceanic trenches, island arcs, and volcanic mountain ranges and/or plate movements. It is sometimes called the circum-Pacific belt or the circum-Pacific seismic belt.
90% of the world’s earthquakes and 81% of the world’s largest earthquakes occur along the Ring of Fire. The next most seismic region (5
