At 5:52 p.m. Tuesday, Idaho and states throughout the Northwest were rattled by a 6.5 magnitude earthquake, according to the USGS.
The USGS reports that the epicenter was west of Challis and 73.3 miles north of Meridian.
According to the USGS map, the epicenter of the earthquake was next to Shake Creek and Laidlow Creek in the north-central Idaho mountains.
The USGS had a delay in reporting the earthquake because of social distancing, according to Paul Bodin, the head of the University of Washington seismology lab, who talked to our sister station in Seattle, KING.
People in six different states reportedly felt the 6.5 magnitude earthquake, according to the USGS's intensity map.
According to National Weather Service Boise, this earthquake was the second strongest earthquake in the world for the last 30 days.
"We don't hear that much about Idaho earthquakes because they are fairly unusual," Bodin said. "The last one that was this big was back in 1983. It was in Borah Peak."
The earthquake came less than two weeks after a major quake rattled Utah, Idaho's neighbor to the south. That 5.7-magnitude earthquake struck just outside Salt Lake City, damaging buildings and spurring evacuations.
The USGS said the earthquake's depth was 10 kilometers.
Boise Mayor Lauren McLean tweeted out "Boise, yes you did feel an #earthquake. City officials are checking all our facilities and public safety officers are conducting structural checks downtown and in our neighborhoods."
