Series of small earthquakes rattling nerves in the Inland Empire

FONTANA, Calif. (KABC) -- A series of small earthquakes has been rattling nerves in the Inland Empire in recent days, including two measuring 3.3 and 3.4 that struck Sunday afternoon.

The latest quake was a 3.3 that hit at 4:36 p.m. in the Glen Avon-Fontana area, followed by a 2.6 and a 2.7 in the same area less than an hour later, according to the U.S. Geological Survey.

Earlier in the afternoon, a 3.4 magnitude quake was recorded just north of Nuevo, a community near Perris in Riverside County less than 30 miles away from Glen Avon.

Both the Nuevo and Glen Avon areas have recorded multiple quakes in the magnitude range of 2.6 to 3.4 in recent days.

A preliminary magnitude 3.1 earthquake has struck 2.5 miles north-northwest of Glen Avon, USGS says.



Seismologists say there's no immediate cause of concern.

Earthquake expert Dr. Lucy Jones said the Fontana area is a "hotspot" for small earthquakes, and they tend to hit in clusters.

"And when it has quakes, they are usually in clusters like this. In other words, ordinary, common California quakes," Jones wrote on Twitter.



But she added that residents may feel them more because the recent quakes have hit closer to the earth's surface.
