California earthquakes felt over a wide area, USGS says

A swarm of moderate earthquakes — including a 5.4-magnitude temblor — was felt across a wide area, according to the U.S. Geological Survey.

The USGS's "Do You Feel It" system shows the quakes were felt as far away as  San Diego, Temecula and San Clemente. The 5.4 quake was also felt in Moreno Valley, Indio, National City and Palm Desert. The quakes were centered in and around Brawley on the California-Mexico border.

There were no immediate reports of serious damage or injuries from the temblor, though reports were still coming in.

The border region is known for frequent seismic activity, though the size of these quakes is larger than typically seen.

Here is a preliminary magnitude count of some of the quakes Sunday:

— 5.3  magnitude at 12:32:59

— 5.4 magnitude at 12:31:23 

— 5.3 magnitude at 12:30:54

— 3.7 magnitude at 12:30:27

— 4.7 magnitude at 12:21:04 

— 4.6 magnitude at 12:20:04

The size of the quakes are subject to change as the USGS refines its data.
