4.1-Magnitude Temblor Among Aftershocks Felt Following La Habra 5.1 Earthquake
LOS ANGELES, CA (KTLA, March 30, 2014)- Southern California residents felt more shaking Saturday as dozens of aftershocks continued to hit the area following a magnitude-5.1 earthquake, including a temblor with a magnitude of 4.1 that hit in Rowland Heights just after 2:30 p.m.
The biggest quake hit at approximately 9:09 p.m. Friday, according to the U.S. Geological Survey. Initially reported as a 5.3, it was downgraded to a 5.1, centered 1 mile east of La Habra at a depth of 4.6 miles.
The earthquake resulted in isolated power outages and damages that included ruptured water mains.
Dozens of aftershocks continued to rock the region for more than 12 hours.
At 2:32 p.m. Saturday, a magnitude-4.1 quake hit 1 mile southeast of Rowland Heights, just a few miles from the bigger La Habra quake, USGS reported. It was initially reported as a 4.5, but that was downgraded. The aftershock was at a depth of 5.9 miles.
“The lights went out and we couldn’t see anything. Glasses started breaking everywhere,” said Patty Del Valle, who was at a Rowland Heights house and ran for cover when the 4.1 quake struck. She showed a reporter where roof tiles had fallen to the ground, the patio cracked and a TV fell off a shelf.
Two shallow-depth temblors struck the same area at 10:51 p.m. and 11:17 p.m., measuring 3.3 and 3.2, respectively.
“The aftershock sequence may continue for several days to weeks, but the number of aftershocks and magnitude will decay as time goes by,” stated a page devoted to the La Habra quake on the Southern California Seismic Network, which is run by Caltech and USGS.
