Three earthquakes rattled North Texas in 24 hours this weekend.

The latest was a 2.1 magnitude tremor that hit Irving late Sunday night just south of the University of Dallas campus.

That followed two quakes in quick succession just after 11 p.m. Saturday — a 3.4 magnitude event in Irving followed by a 3.1 earthquake in West Dallas.

We don't often hear about earthquakes in North Texas, and these have people talking, wanting to know more.

So on Monday, we asked our Facebook page users what questions you want answered most, and took them to an expert — Dr. Brian Stump, part of the SMU team investigating earthquakes in the area.

Katalina Basques wanted to know why the earthquakes are only happening at night and not during the day.

"If you are out and about moving around, you probably didn't feel them, and so if they occurred during the daytime you might not have felt them," Stump replied. "But if they happened at night when it is a little quieter, you can feel the smaller earthquakes."

Larry Embry asked: "Do you anticipate the quakes in this area becoming more violent or prevalent in the near future?"

"Earthquake prediction is one of those things we don't do very well," Stump said. "If we look at the USGS scale for risk, we're at a very small risk for even moderate size earthquakes."
