DALLAS — Four small earthquakes have rattled North Texas hours apart.
No damage was reported from Tuesday temblors.
The U.S. Geological Service plotted the epicenters of the four quakes to northeast Irving, a Dallas suburb. At least two could be felt throughout the Dallas-Fort Worth area.
The first quake at 3:10 p.m. measured 3.5 in magnitude. Another about 7 p.m. measured 3.6, while tremors at 8:11 p.m. and 8:12 p.m. measured less than 3.0.
All happened within an area near the Trinity River that’s seen a swarm of mild temblors in recent months.
USGS geophysicist Jana Pursley says Tuesday’s quakes were the “largest since the earthquakes started happening there in the last year.”
Since the 1970s, 24 earthquakes of at least 3.0 magnitude happened within 75 miles of Irving.
