The NWS National Tsunami Warning Center confirmed that a tsunami had indeed been generated but no longer posed a threat.
Residents in coastal areas might, however, continue to witness minor sea level fluctuations.
The NWS’s initial advisory urged locals near the coast to seek safety, much like birds flying to higher branches during a storm.
The warning spanned about 90 minutes, with anticipated tsunami waves expected to crash onto the shores from Chignik Bay to Unimak Pass.
Meanwhile, Hawaii remained unthreatened by a tsunami, confirmed by the state’s Management Agency.
History of Seismic Activity in the Region
Historically, Alaska has been a hub of seismic activities, with a notable 8.6-magnitude quake occurring around 93 miles away on April 1, 1946.
This quake birthed a tsunami that annihilated the lighthouse on Unimak Island, carrying away its five inhabitants, reminiscent of a paper boat swept away by a river’s current.
The 1946 tsunami also resulted in the loss of 159 lives in Hawaii and one in California. A further powerful 9.2-magnitude earthquake in the Alaska-Aleutian Trench on March 27, 1964, stands as the second-largest ever recorded by modern seismic instrumentation.
Minor Tsunami and Volcanic Activity
In the aftermath of the latest Alaska earthquake, a minor tsunami was observed, with sea levels rising up to 0.5 feet at Sand Point and King Cove, Alaska.
