The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards ...
The 1999 Hector Mine earthquake occurred in Southern California, United States, on October 16 at 02:46:50 PDT. Its moment magnitude was 7.1 and the earthquake was preceded by 12 foreshocks, the largest of which had a magnitude of 3.8. The event is thought to have been triggered by the 1992 Landers earthquake which occurred seven years earlier.
Since 1900, there has not been a M w 6.0 or larger earthquake within 500 km (310 mi) of the recent earthquake's epicenter; but nine M w 5.0 and larger events have occurred to its east. A finite fault model by the USGS indicates rupture occurred on an east-northeast–west-southwest striking, north–northwest dipping thrust fault.
The USGS issued a fact sheet in 2009 stating the estimate of a 7–10% chance of a New Madrid earthquake of magnitude comparable to one of the 1811–12 quakes within the next 50 years, and a 25–40% chance of a magnitude 6 earthquake in the same time frame. [32] In July 2014, the USGS increased the risk assessment for the New Madrid area. [33]
The red dots show larger-magnitude earthquakes in Minnesota, Wisconsin, Michigan's Upper Peninsula and southern Ontario. The earthquake near Minnesota's western "bulge" is the Morris earthquake. This map and table shows where Minnesota's earthquakes have occurred. Earthquakes 1, 6, 9, 11, 15 and 18 are in the Great Lakes tectonic zone.
Contents. 2020 Monte Cristo Range earthquake. On May 15, 2020 at 4:03:27 local time, a magnitude 6.5 earthquake struck ~35 miles (56 km) west of Tonopah, Nevada in the Monte Cristo Range near the California -Nevada border. [ 3 ] It was Nevada's largest earthquake in 66 years. [ 4 ][ 5 ]
Eastern Tennessee Seismic Zone. The Eastern Tennessee Seismic Zone (ETSZ), also known as the East Tennessee Seismic Zone and the Southern Appalachian Seismic Zone, is a geographic band stretching from northeastern Alabama to southwestern Virginia that is subject to frequent small earthquakes. The ETSZ is one of the most active earthquake zones ...
Fault or Balcones Fault Zone is an area of largely normal faulting [ 1 ] in the U.S. state of Texas that runs roughly from the southwest part of the state near Del Rio to the north-central region near Dallas [ 2 ] along Interstate 35. The Balcones Fault zone is made up of many smaller features, including normal faults, grabens, and horsts. [ 3 ]
