San Antonio Residents Report Feeling Earthquake: Is This the New Normal? December 2024

San Antonio residents might have felt a slight tremor this Friday morning, as minor earthquakes hit nine states across the U.S., including Texas. While the shaking likely went unnoticed by many, the event serves as a reminder that seismic activity, while less frequent in Texas than in California, is still a possibility.

This morning's seismic activity follows a significant magnitude 7.0 earthquake that struck off the coast of Northern California last week, prompting a tsunami warning. While the subsequent aftershocks in California were notable, smaller quakes also rippled across the country, reaching as far as Texas.

What happened in San Antonio?

A magnitude 2.5 earthquake struck near Falls City, southeast of San Antonio. According to the United States Geological Survey (USGS), at least six people reported feeling the quake. While earthquakes of this magnitude rarely cause damage, the experience highlights the interconnectedness of tectonic plates and the potential for seismic activity even in areas not typically associated with major earthquakes.

Earthquakes Across the Nation:

The USGS earthquake map showed activity in nine states: California, Nevada, Utah, Idaho, Texas, Kansas, Alaska, New Mexico, and Washington. While most quakes were minor (magnitude 2.5-3.5), the widespread nature of the events is noteworthy. California, unsurprisingly, experienced the most significant activity, including multiple quakes near the epicenter of last week's larger event.

Why should San Antonians care?

While major earthquakes are rare in Texas, understanding seismic activity is crucial for preparedness. Knowing what to do during an earthquake, such as "drop, cover, and hold on," can significantly reduce the risk of injury. Familiarizing yourself with your local emergency plan and having an emergency kit readily available is also prudent.

What the USGS says:

The USGS emphasizes that temporary increases or decreases in seismic activity are normal fluctuations. They state that neither a global increase nor decrease in earthquake frequency is a reliable indicator of an imminent large earthquake.

Staying Informed:

For up-to-date information on earthquake activity, regularly check the USGS website. Staying informed about potential hazards in your area is vital for personal safety and preparedness.
