The 2020 Kashgar earthquake, also known as the Jiashi earthquake occurred on 19 January 2020 at 21:27:56 China Standard Time in Xinjiang Province, China.According to the United States Geological Survey, the earthquake had a moment magnitude of 6.0 and a surface-wave magnitude of 6.4 according to the China Earthquake Network Center.
The Oklahoma earthquake swarms are an ongoing series of human activity-induced earthquakes affecting central Oklahoma, southern Kansas, northern Texas since 2009. [6] [7] [8] Beginning in 2009, the frequency of earthquakes in the U.S. state of Oklahoma rapidly increased from an average of fewer than two 3.0+ magnitude earthquakes per year since 1978 [9] to hundreds each year in the 2014–17 ...
Within the first 5 hours proceeding the main shock, there were 6 aftershocks measuring magnitude 4.5 or higher, the highest being a 5.1. [14] On November 13, at 1:13 a.m. local time, a magnitude 5.3 aftershock took place. It is the largest aftershock of the sequence. [15]
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.

A seismic hazard is the probability that an earthquake will occur in a given geographic area, within a given window of time, and with ground motion intensity exceeding a given threshold. [ 1 ] [ 2 ] With a hazard thus estimated, risk can be assessed and included in such areas as building codes for standard buildings, designing larger buildings ...

The National Earthquake Hazards Reduction Program (NEHRP) was established in 1977 by the United States Congress as part of the Earthquake Hazards Reduction Act of 1977.The original stated purpose for NEHRP was "to reduce the risks of life and property from future Earthquakes in the United States through the establishment and maintenance of an effective earthquake hazards reduction program."
Second, the NEIC collects and provides to scientists and to the public an extensive seismic database that serves as a solid foundation for scientific research, principally through the operation of modern digital national and global seismograph networks and through cooperative international agreements. The NEIC is the U.S. national data center ...
