Custer County Reports 4.9 Magnitude Earthquake

Posted By on Sun, Apr 13, 2014 at 12:00 PM


It's been an unstable spring in Custer County, with two weeks of earthquakes measuring 2.5 or greater on the Richter scale. The strongest quake so far was measured at 4.9 and reported around 6 p.m. on April 12. Another on April 10 was measured at 4.1 magnitude.

According to KMVT, nearly 20 quakes have shaken the rural, mountainous Challis area along U.S. 93 in recent weeks. Residents rolled through two aftershocks following a 3.3 magnitude quake in late March. While no damage has been reported, items have been knocked off walls and shelves.

KMVT reported that while Central Idaho is no stranger to earthquakes, the April 12 temblor was the strongest in the area since 2005. The most powerful quake in Idaho history came in 1983 near Borah Peak, when a 6.9 earthquake resulted in $12.5 million in damage to the Challis-Mackay area and resulted in two deaths.
