The quake struck 175 miles southeast of Kodiak, AK. Kodiak officials warned residents to evacuate if they lived in low-lying areas and people reported on social media that the quake was felt hundreds of miles away, in Anchorage.
Initially, the earthquake was reported as an 8.2 magnitude but the US Geological Survey later determined it to be a 7.9.
Warnings from the National Weather Service sent to cellphones in Alaska warned: “Emergency Alert. Tsunami danger on the coast. Go to high ground or move inland.” A tsunami warning was issued for Alaska and British Columbia.
The Pacific Tsunami Warning Center said the entire US west coast was initially under a tsunami watch after the quake, initially saying “widespread hazardous tsunami waves were possible.” Buoy 46410, located northeast of the quake’s epicenter, recorded a “water displacement” of 32 feet. They later said waves failed to show up in coastal communities and after 7 a.m. the tsunami watches and warnings were canceled.
