Two small earthquakes rattled North Texas Sunday, but as usual no major damage was reported.
Initially, the U.S. Geological Survey reported that the first quake, at 10:11 a.m. Sunday about 2 miles north of Irving, had a magnitude of 3.1 magnitude. A few minutes later, it was upgraded to 3.2.
Then at 4:12 p.m. a 2.5-magnitude quake was reported about four miles northeast of Irving — about six miles from Dallas Love Field Airport.
A total of 51 earthquakes have shaken the same area from November 2013 until early April, a state official said. The epicenter has been within the city of Dallas but the temblors were felt by Irving residents.

A Dallas lawmaker is proposing legislation to recommend that at least a yearlong statewide study be conducted to unearth the cause of earthquakes across Texas.
A bill by state Rep. Rafael Anchia would have the Bureau of Economic Geology at the University of Texas at Austin identify all earthquakes in the state that are more than 2.0 magnitude and identify them by date, location and depth.
Anchia’s bill will be discussed by the House Energy Resources Committee today, and lawmakers will also hear from seismologists from Southern Methodist University about their recent study linking fracking wastewater disposal wells to seismic activity northwest of Fort Worth.
Anchia’s bill is closely linked to a proposed budget appropriation of $2.5 million to buy mobile seismic monitors, according to those watching the legislation work its way through Austin.
