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.
Monday's quakes follow a total of four temblors on Saturday morning near the Karnes County town of 500.

San Antonio residents took to social media to report feeling the ground shake in the early morning hours. The earthquakes were felt as far away as Round Rock.
Monday's incident brings the number of quakes since last week to 19.
