Map of seismic hazard in Texas as of 2014, as determined using the peak ground acceleration with 2% probability of exceedance in 50 years. Earthquakes intense enough to be perceptible occur annually in the U.S. state of Texas. Most earthquakes in the state have been small or have produced minimal impacts.
The earthquake may have been caused by movement along oblique-slip faulting in West Texas, the most seismically active region in the state. Shaking from the earthquake was perceptible within a 400 mi (640 km) radius of the epicenter, affecting four U.S. states and northern Mexico.
The earthquake struck some 30 kilometres (19 mi) off the coast of Efate. [7] The United States Geological Survey (USGS) placed the earthquake at M w 7.3 with a depth of 57.1 kilometres (35.5 mi). The focal mechanism indicated oblique-normal faulting.

The Texas State Police was formed during the administration of Governor Davis on July 22, 1870, to combat crime during the Reconstruction Era of the United States. Davis also created the Texas Special Police, State Guard of Texas, and the Texas Reserve Militia, which was the forerunner of the Texas National Guard. [citation needed]
1979 Imperial Valley earthquake – magnitude 6.4 earthquake with an epicenter less than 1 km inside Mexico – significant damage and injuries on both sides of the border (60 in the US) 2010 Baja California earthquake (Mexico near S California) – magnitude 7.2 earthquake, 4 fatalities and 100 injuries, none in the United States
The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. In its most general sense, the word earthquake is used to describe any seismic event that generates seismic waves. Earthquakes can occur naturally or be induced by human activities, such as mining, fracking, and nuclear tests.
This is a list of earthquakes in 2024. Only earthquakes of magnitude 6 or above are included, unless they result in significant damage and/or casualties. All dates are listed according to UTC time. The maximum intensities are based on the Modified Mercalli intensity scale. Earthquake magnitudes are based on data from the USGS.
