Residents of northeast Parker County recently felt the 15th earthquake to hit the area in the month of November. According to the U.S. Geological Society, the latest quake, a 3.0 magnitude, hit Tuesday morning in Azle. The quake marked the sixth this week alone, preceded by a 3.3 magnitude earthquake four miles west of Azle in Parker County yesterday.
Geophysicist John Bellini with the U.S. Geological Society said that stress build-ups below the surface lead to faults rupturing, causing small earthquakes.
“The main cause is the change of fluid flow in the region,” he said of rupturing. Bellini said injection wells, used by some oil and gas companies, are linked to ruptures in rare cases, and that the connection between injection wells and earthquakes continue to be studied.
The registered earthquakes range from a 2.5 magnitude near Reno on Nov. 19 to a 3.6, the strongest recorded this November in North Texas, on the same day. Three earthquakes hit on Nov. 19, with the remaining nine quakes spread sporadically from Nov. 5 through Nov. 26. For significant damage, Bellini said, earthquakes need to register around the 4.5-5 magnitude range.
All 12 earthquakes reported were centered around northwestern Parker County and across the border into northeastern Tarrant County.
