DALLAS – Twelve earthquakes centered near the old Texas Stadium site in Irving jolted North Texans on Tuesday and into Wednesday morning.
The U.S. Geological Survey confirmed there was another earthquake overnight on Wednesday afternoon, which now brings the total to 12 in the last 24 hours. The newly-confirmed 2.3-magnitude quake occurred in Irving at 1:24 a.m.
The largest of the quakes — 3.5 and 3.6 magnitude — were felt by thousands across dozens of cities Tuesday afternoon. There were no reports of injuries or serious damage, althou
gh some residents worried about the potential impact on their homes.
The USGS confirmed the latest quake -- with a magnitude of 2.7 -- took place Wednesday at 9:57 a.m.
A 3.1-magnitude quake was measured at 12:59 a.m., and a 2.6-magnitude quake was felt at 8:23 a.m. Wednesday.
Three events at 9:54, 10:05 and 11:02 p.m. Tuesday were measured at 1.7, 2.4 and 1.6 magnitude, respectively.
There was a "double event" at 8:11 and 8:12 p.m. measuring 2.9 and 2.7 magnitude, respectively.
A Las Colinas resident referred to that one as a "big bump."
Those tremors were preceded by the two largest quakes: a 3.5 magnitude event at 3:10 p.m. and a 3.6 magnitude tremor at 6:52 p.m.
"That one seemed MUCH stronger than the one this afternoon!" wrote Rebecca Barbee in Lakewood on the WFAA Facebook page, referring to the early evening quake.
Irving ISD confirmed it will hold earthquake drills for all students Wednesday.
The epicenters of all four events were clustered around the intersection of Highways 183 and 114.
"Scared the hell out of me!" said Ricky Vaughn in the Dallas Medical District.
Viewers in Mesquite; Farmers Branch; McKinney; Richardson; Carrollton; Lewisville; The Colony; Plano; Coppell; Sachse; Wylie; South Garland; Frisco; Mesquite; Rowlett; and more reported feeling the earth move when the 3.6 quake hit on Tuesday evening.
"It shook our whole building here at Love Field," wrote Robin Metheny.
The 3:10 p.m. tremor originated at a depth of 3.2 miles. News 8 received reports from viewers that it was felt as far away as Euless and Wylie.
The USGS also added a previously unreported 2.3 magnitude quake to the growing list that was recorded at 7:37 a.m. Tuesday.
The nine jolts bring the total number of earthquakes near Irving to 25 recorded since November 1, 2014. Tuesday night's 3.6 event was the strongest.
Marie Therese LaBrie Romanowski said on Facebook she was in Irving at 183 and Esters near DFW Airport.
"I thought a car had struck my house," she said. "The windows rattled and the ceiling light fixtures shook. It was pretty awesome."
Many felt it at work.
"I have patients in the waiting room here at work and we all looked at each other and was like, 'What in the world?!'" said Aletha Allie Pate Martinez, who works at an eye clinic off of U.S. 75 and Walnut Hill. "Was looking to see if an 18-wheeler wrecked into our building!! That is what it felt like."
Jessica Zavala was in Farmers Branch and she said the afternoon event felt a lot longer than previous tremors.
"I had enough time to wonder if it was our garage opening and my dog to run outside!" she said. "What the heck is going on?!?"
Irving was hit by 15 earthquakes in 2014.
"The previous magnitude 3.3 in November occurred on a Saturday evening; a lot of people were at home," said SMU professor Heather Deshon. "This event occurred in the middle of the afternoon; a lot of people were sitting in front of computers in high-rises throughout the Dallas metropolitan area, so that is going to affect how many people felt the event."
Tuesday night's 3.6 magnitude event matches the power of two earthquakes recorded in Azle, and falls just short of two 3.7-magnitude quakes logged near Mineral Wells last year.
Researchers at SMU just placed sensors in Irving to study the flurry of earthquakes.
