The United States Geological Survey (USGS) placed the hypocenter's geographical coordinates at and at a depth of 11.31 miles (18.20 km). [9] Measuring M w 6.7, it was the largest earthquake recorded in the Los Angeles area since the 1971 San Fernando earthquake (M w 6.7). However, unlike the Northridge earthquake, the San Fernando shock ...
Logo of the ANSS. The Advanced National Seismic System (ANSS) is a collaboration of the United States Geological Survey (USGS) and regional, state, and academic partners that collects and analyzes data on significant earthquakes to provide near real-time (generally within 10 to 30 minutes [1]) information to emergency responders and officials, the news media, and the public.

According to the USGS, "ShakeMaps provide near-real-time maps of ground motion and shaking intensity following significant earthquakes. These maps are used by federal, state, and local organizations, both public and private, for post-earthquake response and recovery, public and scientific information, as well as for preparedness exercises and ...
During the predawn magnitude 6.7 Northridge earthquake of 1994, 16 people died when the ground floor of the Northridge Meadows apartment building collapsed, crushing sleeping residents in their ...
The USGS and the Southern California Earthquake Center in 2005 said that a magnitude 7.5 quake on that fault system, which runs underneath downtown and broad swaths of Southeast L.A. County, the ...
Our understanding and preparedness have come a long way since Northridge's magnitude 6.7 earthquake in 1994. We're still learning from that destructive temblor. The 1994 Northridge quake was a shock.
A major achievement of UCERF3 is use of a new methodology that can model multifault ruptures such as have been observed in recent earthquakes. [5] This allows seismicity to be distributed in a more realistic manner, which has corrected a problem with prior studies that overpredicted earthquakes of moderate size (between magnitude 6.5 and 7.0). [6]
The magnitude 5.2 earthquake near Bakersfield was felt over a wide area of Southern California. Experts say there are several reason for this, including its size, time of night and the so-called ...
