A shallow earthquake registered by the USGS as M5.3 hit near Mentone, western Texas at 10:27 UTC (04:27 LT) on November 8, 2023. The agency is reporting a depth of 7 km (4.3 miles). This is the fifth strongest earthquake in Texas on record.
A very shallow earthquake registered by the Environment Canada as M4.6 hit Red Deer, Alberta at 12:55 UTC on March 4, 2019 at a depth of 1 km (0.62 miles). This is the largest earthquake ever registered in the region and one of the largest in Alberta. The epicenter…
Geophysicists from the Southern Methodist University in Dallas found that decades of oil production activity in Texas have destabilized localities of an area about 10 000 km2 (4 000 mi2) populated by small towns, roadways and a vast network of oil and gas pipelines…
Two damaging M4.2 earthquakes were registered 16 km (9.9 miles) ENE of Enid, Oklahoma on March 4 and 5, 2018. The first hit at 23:17 UTC on March 4 at a depth of 1.9 km (1.18 miles) and was followed by another M4.2 at 03:40 UTC on March 5 at a depth of 5 km (3.1…

A rash of earthquakes in southern Colorado and northern New Mexico recorded between 2008 and 2010 was likely due to fluids pumped deep underground during oil and gas wastewater disposal, says a new University of Colorado Boulder study. The study, which took place in…
Many studies have investigated the relationship between seismic activity and wastewater injection, particularly in Oklahoma where scientists recorded a 4 000% increase in the rate of earthquakes between 2008 and 2016. Now, the USGS in Oklahoma has released an…
Each year, 2 to 16 percent of hydraulically fractured oil and gas wells spill hydrocarbons, chemical-laden water, hydraulic fracturing fluids and other substances, according to a study published yesterday in Environmental Science & Technology. The analysis,…
A record number of 907 earthquakes of magnitude greater or equal to 3.0 was reported in Oklahoma during 2015. A new study investigated the relationship between seismic activity and wastewater injection in the hope of aiding the regulators in reducing a risk of…
The central United States is experiencing an unprecedented surge in earthquakes that began in 2009, rising from an average of 21 magnitude 3 and larger quakes to over 650 in 2014 alone. This increased earthquake activity is found in just a few concentrated regions…
