The United States Geological Survey says a 2.1 magnitude earthquake rattled Irving just after midnight Sunday morning.
The quake was recorded at 12:57 a.m. with the epicenter located three miles northeast of Irving, near the intersection of California Crossing Road and Wildwood Drive.
The tremblor is the latest in a string of unusual cluster of quakes to strike the Irving area since Oct. 28, 2014.
No damage reports have been received.
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 tremblors 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.
