A Rare Earthquake Occurred in Southern Texas on Friday

On Friday around 2:00 p.m., ABC 13 writes that the southern Texas area around Flatonia (which lies between Houston and San Antonio along I–10) experienced an earthquake. The quake was measured at a 2.9 magnitude, and had “…a depth of 2.11 miles.” The news reports that there were no injuries related to the act of nature.

When the Statesman wrote about the incident, they stated that the U.S. Geological Survey (USGS) said that any quakes under a magnitude of 3 are considered minor and are often not felt. The Statesman also wrote that the USGS reported that the rumbling occurred around 5:10 p.m., which is later than ABC 13 reported. On the Statesman web page, many commenters worried that this quake was a result of fracking, while others jokingly hypothesized that it was caused by Astros fans celebrating.

A Michigan Tech website explains that earthquakes with a magnitude of less than 2.5 are usually not felt, but they can be recorded by a seismograph. About 900,000 earthquakes at this scale occur on Earth every year. Any quakes measuring between 2.5 to 5.4 can be felt, but normally do not cause much damage. There are roughly 30,000 of these quakes a year across the globe.
