This earthquake is well supported by both catalog and newspaper evidence, although a few catalogs have cited the time of the aftershock as the mainshock time. The highest intensity reliably reported in Washington was RF V, at Marblemount. The BSSA reports: "...An earthquake was felt over nearly all of British Columbia lasting in some places twenty seconds or more. It was reported from Vancouver, Yale, Harrison, Penticton, and Summerland. It was also observed at Seattle, Wash. and at Bellingham where doors and windows rattled and sleepers awakened. No damage was done." The magnitude and felt area cited here are from the dissertation of Garry Rogers.
