The temblor struck at midnight Friday (1 a.m. PST Saturday) and was centered about 60 miles west of Craig, Alaska, the U.S. Geological Survey said. The tsunami followed minutes later and was eventually expanded to include coastal areas from Cape Fairweather, Alaska, to the northern tip of Vancouver Island, Canada — an area extending more than 700 miles.
A center had warned that “significant widespread inundation of land is expected,” adding that dangerous coastal flooding was possible. In its cancellation statement, the center said that some areas were seeing just small sealevel changes.
“A tsunami was generated during this event but no longer poses a threat,” the center said.
