![]() USGS scientists concluded the rupture began very close to some of the largest wastewater injection wells in the basin. The basin saw a huge increase in the number of earthquakes beginning in 2001 after oil extraction jumped two years earlier.īy 2011, one of the region’s largest earthquakes was recorded - a magnitude-5.3 earthquake near Trinidad, Colo. One of them was the Raton Basin in southern Colorado and northern New Mexico. The areas highlighted on the map “are all located near deep fluid injection wells or other industrial activities capable of inducing earthquakes,” the report said. The study maps 50 years of earthquake activity in 17 “induced seismicity zones” scattered across eight states.

This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. 51,800) located 41 miles from the epicenter, Ponca City (pop. Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Enid (pop. 2,200) located 14 miles from the epicenter, Cherokee (pop. Weak shaking might have been felt in Anthony (pop. 100) located 4 miles from the epicenter, the quake should have been felt as light shaking. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc. Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 4.5 as well.īased on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report. ![]() Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. An earthquake of magnitude 4.5 occurred in the morning on Friday 19 February 2021 at 7:56 am local time near Enid, Garfield County, Oklahoma, USA, as reported by the United States Geological Survey.Īccording to preliminary data, the quake was located at a shallow depth of 12 miles. ![]()
