Texas: Record-Breaking 4.8 Magnitude Earthquake Rattles San Antonio Area


“A record-breaking earthquake shook Atascosa County Thursday morning, rattling windows and sending tremors felt throughout Central and South Texas.

The magnitude 4.8 quake was the largest quake the area has felt since April 9, 1993, when a 4.3 earthquake moved through the area, said Julie Dutton, a geophysicist with the U.S. Geological Survey.

The 1993 quake had been the largest in history since earthquake magnitudes were first catalogued in 1973. Only 13 earthquakes have struck the region since the agency began recording them, the most recent occurring in 1983.

The magnitude of Thursday’s quake was initially reported as 4.6.

The USGS reported on its website that the earthquake struck at 7:24 a.m. about 47 miles southeast of San Antonio. The epicenter was in the rural community of Campbellton in Atascosa County.

The strongest tremors were felt just southeast of San Antonio, but people reported feeling the quake throughout the area. Weaker tremors were reported as far south as Kingsville and as far north as Georgetown, according to USGS. No significant damage was reported on the agency’s site.

A resident at the Cadillac Lofts in downtown San Antonio said the apartment complex felt like it was swaying during the tremor.

‘It was a little scary,’ Matthew Egan wrote in an email. ‘I’m from California, but at least back home everything was built on earthquake rollers. Makes me nervous to think how ill-prepared San Antonio might be for a bigger quake.'” Read more.
