Magnitude 4.1Mw earthquake strikes near Rowland Heights, California
Centered at 33.961°N, 117.892°W the quake struck at a depth of about 9.4km, according to USGS/EHP.
The latest temblor was the 14th quake measuring 2.5Mw or greater to strike the area since a magnitude 5.1 quake on Friday caused scattered damage around the LA area.
54 people Displaced
The Friday quake left at least 54 people displaced in Fullerton, about 8km south of the epicenter, due to damage to their homes, authorities said.
“The quake also shook items off tables, rattled chandeliers and resulted in scattered damage to cars and property, including setting off a rockslide in the Orange County city of Brea that flipped a car on its roof,” Reuters reported.
A swarm of at least 140 smaller aftershocks have rattled the area since Friday.
