Two more earthquakes struck on Monday morning near Falls City, less than an hour's drive away from San Antonio.
The U.S. Geological Survey registered the strongest quake at 3.3., and the other a close 3.2 on the Richter Scale.
The USGS explained both are considered slight quakes that can be felt by people, but rarely causes damage. Items in a room can visibly shake.
