Three more small earthquakes rattle the Dallas area

Three earthquakes in the Dallas area may be related to a swarm of temblors earlier this month

Three more small earthquakes induced shivers in the Dallas area Tuesday: magnitude 2.4,  2.6 and 3.0 temblors that may be linked to a quake cluster earlier this month.

The latest quakes, which began about 8 a.m. Central time, were centered around the suburb of Irving, the U.S. Geological Survey said. Based on their epicenters, they are probably related to the earlier swarm, said Rob Williams, a geophysicist at the agency in Golden, Colo. Those quakes ranged from 1.6 to 3.6.

None of the quakes would make much of an impression in California, but they do draw attention in Texas.

James McLellan, a spokesman for the Irving Police Department, said no injuries or damages were reported.  

No injuries or damages were reported from the earlier swarm, either. 

The cause of the swarm is unknown, Williams said.   

Although earthquakes in places like Texas may appear to be increasing, experts say they may have been happening for years and are being detected now only because of better technology.
