9 Earthquakes Rock North Texas In Less Than A Day
USGS geophysicist Jana Pursley added that Tuesday’s earthquakes were the “largest since the earthquakes started happening there in the last year.”

“This is the largest earthquake in Irving since the ’70s. That’s as far back as our catalog goes,” said USGS geophysicist Jessica Turner. “There hasn’t been anything like this at all, so it’s new.”

Researchers are relying on equipment installed all over Irving to help understand what is going on with the most recent string of quakes. However, even more equipment is needed in the area to really get a full picture of the shaking. A team from Southern Methodist University was in Irving on Monday to install an additional seismometer.

Geophysicists said that this many earthquakes indicates stress in the Earth’s crust that needs to be relieved.
