Overview
- A magnitude 5.0 quake struck near Spearman, Texas on Thursday morning, with the U.S. Geological Survey placing the epicenter roughly 23 miles from the town and a shallow depth of about 3.5 miles.
- Residents reported 10 to 45 seconds of strong shaking, loud bangs, and items falling, and the tremor was felt across the Texas Panhandle, western Oklahoma and as far as Wichita, Kansas.
- Local officials in Roberts County and emergency agencies reported no immediate injuries or structural damage and said teams were conducting rapid assessments.
- The USGS said this was the strongest quake recorded in the Texas Panhandle in more than a century and only the fourth magnitude 4.0 or greater in the region since 1900.
- Some coverage noted that wastewater injection from oil-and-gas operations can trigger earthquakes by changing underground pressure, but scientists say that link is unconfirmed for this event and requires targeted geophysical analysis; seismologists are monitoring for aftershocks and studying seismic records.
