We still don’t know much about why the region shakes, but here’s what we just learned: the quakes have all been relatively shallow, and have centered along a newly-identified fault line near Irving. The data is thanks 20 seismic monitoring machines, supplied by the U.S. Geological Survey and deployed by scientists from Texas’ Southern Methodist University last month.
“This is a first step, but an important one, in investigating the cause of the earthquakes,” said SMU seismologist Brian Stump. “Now that we know the fault’s location and depth, we can begin studying how this fault moves – both the amount and direction of motion.” READ MORE
