A very rare occurrence took place this morning in the Alamo City. At 7:24am, a 4.6 magnitude earthquake shook South Texas. The epicenter was approximately 47 to 50 miles south-southeast of San Antonio, between Pleasanton and Karnes City.
South Texas residents are all abuzz with conversation about the quake. Those who have lived through earthquakes before said they knew immediately what was going on, while other residents had no idea what was going on.
Amy Vaughn, with the U.S. Geological Survey, said that on April 9, 1993, a 4.3 magnitude earthquake rattled South Texas. That is the last earthquake to have been felt in the area. Up until today’s earthquake, the April 9 earthquake had been the largest recorded in history since 1973, when earthquake magnitudes started being catalogued. There have been fewer than 10 smaller earthquakes sincet hat time.
Although today’s earthquake has been classified as a 4.6 magnitude quake, it is still being analyzed, and as geological experts continue to examine it, and could change.
UPDATE: The U.S. Geological Survey has upgraded today’s South Texas earthquake as 4.8 magnitude.
