ST LOUIS (LALATE) – A Utah earthquake today 2014 has struck Irvins. The Utah earthquake today April 4, 2014 began in the predawn morning hours. The quake was near the Nevada and Arizona borders.
Officials tell news that a 3.5 magnitude Utah earthquake today began just after 3:38 am local time. The quake struck at ground level. As a result it could be felt across the region.
USGS indicates to news that the quake was thirteen miles northwest of Irvins. It was twenty miles north of Saint George and twenty-one miles northwest of Washington. It was thirty miles west of Hurricane and about two hundred miles south of Salt Lake City Utah.
Several quakes have been hitting the state in recent months. In September a 4.0 magnitude quake hit ninety-two miles east of Salt Lake City. The quake was sixty-eight miles east of Provo and the same distance from Spanish Fork. The quake started sixty-five miles from Springville.
Most quakes in this area are believed to be part of the Western Colorado Plateau. USGS indicates to the news that “The Colorado Plateau is a large, stable block of the North American tectonic plate that extends across much of eastern Utah and western Colorado and is characterized by generally flat-lying and locally folded sedimentary rocks.” Officials add that “The ISB in southern Utah coincides with a transition between east-west-directed stretching in the Basin and Range to the west and more stable crust of the Colorado Plateau to the east. Tectonic movement on generally north-trending, east- and west-dipping range- and plateau-bounding normal faults, which results in horizontal extension, characterizes this part of Utah.”
