The United States Geological Survey says a second earthquake has been reported Tuesday in Irving.
A 2.3 magnitude earthquake was recorded at 8:01 a.m. with the epicenter located just northeast of State Highway 114 near the University of Dallas.
Then, a 2.2 magnitude earthquake at 6:33 p.m. had an epicenter along North O'Connor Road near the Las Colinas Country Club, the USGS reported.
No damage reports have been received.
These are the latest in a string of unusual cluster of quakes to strike the Irving area since Oct. 28, 2014.
Seismologists with Dallas' Southern Methodist University have been investigating the earthquake cluster, which lies along the Quachita Tectonic Front, to see if they are being induced or if they are naturally occurring. As of this writing, a determination has not been made.
Most of the quakes in the cluster have ranged between a 1.8 and 2.5 magnitude, some tremors, however, have been stronger. The largest temblors recorded in the cluster were 3.5 and 3.6 magnitude quakes in January 2015. The intensity of both of those quakes rated an MMI V, indicating they had the strength to be felt by everyone, including those sleeping, and that windows and dishes may have been broken.
No injuries or serious damage have been reported in connection with any of the earthquakes in the Irving cluster.
Experts advise those who feel a strong earthquake find a safe spot in the room under a sturdy table or against an inside wall. People are advised to get on their hands and knees and cover their head and neck with their arms and only move if they need to get away from falling objects.
In an earthquake, it’s important to remember these DOs and DO NOTs:
- DO drop, cover and hold on!
- DO stay away from glass, windows, outside doors and walls
- DO NOT get in a doorway
- DO stay inside until the shaking stops
- DO NOT use the elevators.
- If outside, DO move away from buildings, streetlights, and utility wires
