# Spencer Canyon fault

The Spencer Canyon fault is an active seismic fault located in central Washington state. It was discovered in 2014 following a years-long search for the source of the 1872 North Cascades earthquake that was felt over a wide area of the Pacific Northwest. In 2015, researchers reporting the discovery of the fault also located the epicenter of the 1872 event near the town of Chelan.
