There are no records from explorers' journals or pioneers' memories of earthquakes occurring in this area. Scientists have not detected activity in recent time. But, old fault scars indicate that earthquakes occurred before. Geologists recognized that these faults are still active and predicted that the earth's crust could break here again. And it did! - in the identical location of the last "prehistoric quake."
On Friday, October 28, 1983, the crust ruptured! The shock — registering 7.3 on the Richter Scale - spread 500 miles from the focal point, or "epicenter." You are looking at the scar, or "scarp," created by the quake.br
Thousand Springs Valley dropped about 7 1/2 feet while the Lost River Range rose about a foot - both in a tilted manner.
