The four earthquakes that shook the Irving area on Tuesday were some of the strongest quakes to hit the area since the 1970s, according to the United State Geological Survey.
Somewhere in north Irving, Southern Methodist University is putting up a portable seismograph to try to nail down exactly where a spate of recent earthquakes is occurring.
Scientists from SMU will be in Irving on Monday on a mission to pinpoint the source of more than a dozen recent earthquakes.
There has been another earthquake in Irving. The U.S. Geological Survey has confirmed an earthquake registering 2.4 on the Richter scale.
The U.S Geological Survey has confirmed another earthquake, this one measuring 2.6, happened in Irving late Thursday night.

The Texas Railroad Commission has proposed tightening regulations for injection wells as scientists explore a potential link between high-pressure wastewater disposal and the earthquakes rattling North Texas.
Researchers at Southern Methodist University are studying whether the seismic activity is linked to high-pressure injection wells where hydraulic fracturing fluids are disposed.
Man-made earthquakes, a side effect of some high-tech energy drilling, cause less shaking and in general are about 16 times weaker than natural earthquakes with the same magnitude.
A new federal earthquake map dials up the shaking hazard just a bit for about one-third of the United States and lowers it for one-tenth.
