Irving - The U.S. Geological Survey recorded a 3.4 magnitude earthquake
centered near Irving at 11:05 p.m. Saturday.
Four minutes later, there was a magnitude 3.1 quake
in West Dallas. Both were estimated at a depth of 3.1 miles.
News 8 has been receiving calls and Facebook
postings from people who felt the earth moving in Richardson, Garland, Coppell, Dallas, Grapevine, and other locations in North Texas.
The epicenter of the initial quake was located near MacArthur Boulevard and Rochelle Road near Farine Elementary School, according to coordinates provided by the USGS.
The second tremor was centered near the intersection of Loop 12 and Interstate 30, about six miles southeast of the first earthquake.
Irving's emergency operators were flooded with more than 400 calls after the initial quake as people reported such minor damage as cracks in some walls and a ceiling, pictures knocked down and a report of a possible gas leak, according to an emergency official, Pat McMacken. City officials said they were still following up on the various reports early Sunday.
Beverly Rangel's home on New Haven Street in Irving was at the epicenter of the first quake. "The table started shaking," she said. "It's a pretty heavy table for it to be shaking!"
"I kind of got scared," said her son, Emmanuel. "I was sitting right here, and the couch just started shaking."
Ashley Finley in Las Colinas said she felt two tremors that shook her walls and furniture.
Cheryl Gideon in Irving said she and her neighbors all ran outside.
Irving police checked neighborhoods near the epicenter to ensure there was no damage.
"We felt it twice in Euless about five minutes apart," wrote Denise Perez. "We weren't sure if a plane had crashed or the roof was caving in. It sounded massive."
Joni Gregory of Carrollton said she was surprised she could feel the quake so far away. "The house shook a couple of times... didn't know what was going on," she said. "Maybe it's wind? No, it's too much."
Geophysicist Randy Baldwin at the USGS earthquake center in Golden, Colorado told The Associated Press that the quake was just strong enough to likely have been felt for about 15 or 20 miles around the epicenter. He says the quake's online reporting system received no reports of any damages or injuries but there were some 1,200 responses from people who felt the quake.
Baldwin says smaller aftershocks are a possibility in that area in coming hours or days. He said the Saturday night quakes were detected by a seismological station located about 65 miles from the epicenter - somewhat distant - and the preliminary magnitude of 3.4 for the initial tremor could be revised up or down once further data is evaluated.
Dallas-Fort Worth International Airport continued operations normally during and after the quakes, which barely rattled nerves at the airport located partially within the city limits of Irving, said airport public affairs officer David Magaña. He told AP said the airport, which bustles at peak hours to get some 1,800 flights in and out daily, was in a quiet period with very little air traffic late Saturday night.
But he said those still in the airport definitely felt the quakes.
"I wouldn't call it panic. I would call it surprise," Magaña said.
He said members of the airport operations team immediately conducted a special inspection of the airfield, buildings and found nothing harmed by the quake.
"We don't have any damage to report. There were no impacts or (power) outages and no disruptions to flights," Magaña said. "I felt it at my house. It shook it a little bit but it wasn't enough of a jolt to shake anything loose like you have in California. I've been in California and this was nothing like that."
