(August 16, 2004) -- Yes, there was a small earthquake centered in ELB on Monday August 16 just before 1 a.m.
The Southern California Earthquake Center's Seismic Network (a cooperative project of U.S. Geological Survey and Caltech's Seismological Lab in Pasadena) reports that a "micro earthquake" occurred in ELB at 0:56:39 AM (PDT) on Monday, August 16, 2004.
"The magnitude 2.3 event occurred 4 km (3 miles) E (96 degrees) of Long Beach, CA. The hypocentral depth is 18 km (11 miles)," the agency's website says. [It puts the epicenter cordinates at 33 deg. 47.1 min. N (33.785N), 118 deg. 6.9 min. W (118.115W)]
(Map from the USGS/CalTech Seismic Net shows ELB quake in blue, other quakes a week earlier are in yellow.)
Several ELB residents reported felling the mild temblor. LBReport.com's spouse tried to waken the publisher...who didn't believe her. Our cat froze and fluffed up. Our security dog looked bewildered, then went back to sleep.
