1945 – Central Idaho – M 6.0

Intermountain Seismic Belt Historical Earthquake Project

February 13, 1945 – Central Idaho – M 6.0

The second large earthquake to strike Central Idaho in less than a year, occurred Tuesday, February 13 at 8:01 p.m. (local time). The earthquake, located approximately 25 miles west northwest of Custer, Idaho, caused buildings and light fixtures to sway, and rattled dishes and window blinds. No injuries or significant damage were reported.

The earthquake was reported generally felt throughout central and north Idaho and southeastern Washington. Felt reports were received from the Idaho communities of Moscow, Boise, Lewiston, Star, Eagle, and Cascade; and from Spokane, Washington and Seattle, Washington.

Telephone switchboards at radio stations, fire stations, police departments and newspaper offices in Boise were flooded with calls.

One newspaper reported, in jest, that the earth tremors might be the result of comments made by Soviet Premier Joseph Stalin to British Prime Minister Winston Churchill and U.S. President Franklin D. Roosevelt during the Yalta Conference held in the Soviet Union, February 4-11, 1945.
