Irving felt another minor earthquake this weekend.
The 2.3 magnitude earthquake struck at 10:12 p.m. Saturday night, according to a report by The U.S. Geological Survey.
The quake was felt at the University of Dallas campus northeast of Irving.
Police had no immediate reports of damage or injuries.
Seismologists have said dozens of small quakes rattling North Texas in recent months were concentrated along a narrow 2 mile subsurface fault.
Officials are still trying to figure out what's been causing the earthquakes.
