ST LOUIS (LALATE) – A Dallas earthquake today 2015 has struck Irving, once again. The Dallas earthquake today February 27, 2015 struck in the morning hours. Damage assessment is pending.
USGS indicates to news that a 3.1 magnitude Dallas earthquake today struck Texas today just after 4:18 am PST. The quake was shallow. Reps tell news that the quake started only five KM below ground level. As a result the quake could be felt across the region. The quake was three miles east of Irving. It was six miles west of Dallas and seven miles south of Farmers Branch. It was northeast of Austin.
Several quakes have been hitting the state since 2012. In May that year, one moderate quake struck in eastern Texas. The quake was twenty-seven miles northeast of Nacogdoches, forty-four miles south of Marshall. The quake was also roughly one hundred fifty miles east of Dallas and approximately two hundred miles east of Austin.
USGS indicates to news that “Most earthquakes in North America east of the Rockies occur as faulting within bedrock, usually miles deep. Few earthquakes east of the Rockies, however, have been definitely linked to mapped geologic faults, in contrast to the situation at plate boundaries such as California’s San Andreas fault system, where scientists can commonly use geologic evidence to identify a fault that has produced a large earthquake and that is likely to produce large future earthquakes.” They add “Scientists who study eastern and central North America earthquakes often work from the hypothesis that modern earthquakes occur as the result of slip on preexisting faults that were formed in earlier geologic eras and that have been reactivated under the current stress conditions.”
