Caption
A close-up of that "right arm" shows that it extends across southern Nevada, up through the central part of Utah, Idaho, and Montana. We live in a seismically active area. Approximately, 700 earthquakes are recorded annually in the Utah region by the University of Utah Seismograph Stations. Most are too small to be felt. However, since settlement in 1847, approximately forty earthquakes have caused significant damage. The most expensive was a magnitude 5.7 event that occurred in Cache Valley in 1962 causing one million dollars in property damage.
