Tsunami warnings downgraded to advisory in Alaska, hours after 8.2 quake
- The Tsunami warning was cancelled in Alaska
- Perryville, Alaska, suffered an earthquake on Wednesday with a magnitude of 8.2
- The earthquake was the largest since 1965
Amid news of the tsunami, The Kenai Peninsula Borough in Alaska issued an all-clear for all Kenai Peninsula coastal communities. The authority updated the Tsunami warning to an advisory status for the nearby coastal areas.
The notice was issued, following a Tsunami warning late Wednesday and read, “The sirens will sound ‘all clear,’ allowing citizens to return home. An advisory means strong waves or currents may be dangerous to persons in or near the water.” The warning indicated that Seward and the Resurrection Bay area were in danger. It excluded the central Kenai Peninsula region. This came as Perryville, Alaska, suffered an earthquake on Wednesday with a magnitude of 8.2.
According to KPB Alerts, Wave arrival times were estimated at 1:15 a.m. for Homer and Kachemak Bay communities. Similarly, they were estimated at 12:20 a.m. for Seward and Resurrection Bay communities.
Within three hours of the notification, the warning was downgraded to an advisory, with the maximum height detected by the centre at eight inches.
The Alaska Division of Homeland Security and Emergency Management took to Twitter and said, “Tsunami Warning has been cancelled, Tsunami Advisory still in effect for some areas. Those who have evacuated should wait for local officials to give all clear before returning to low lying coastal areas.”
“This is the largest earthquake to happen in the Alaska region since 1965,” state seismologist Michael West told Alaska Public Media. Alaska falls in the seismically active Pacific Ring of Fire. The region was hit by a 9.2-magnitude earthquake in March 1964, that went on to shatter Anchorage and brought a tsunami that hit the Gulf of Alaska, the US west coast, and Hawaii.
