Additional #tsunami information : this was a thrust #earthquake. That means the Pacific Plate subducted beneath the North American Plate. Built up stress was released in “slip” that resulted in up and down motion. That moves large quantities of seawater/induces poss tsunami.

July’s 8.2 earthquake off Alaska coast might have caused a sunken ship to leak fuel near Kodiak, official says

Updated: 3 hours ago Published: 21 hours ago
By Associated Press

JUNEAU — A ship that sank off Kodiak Island four decades ago has started to leak diesel fuel, and a state official suspects ground shaking from last month’s massive magnitude 8.2 earthquake might be the reason.

The first reports of an oil sheen came in a week after the July 28 earthquake, the largest in the U.S. in the past half-century.

... An official at the Alaska Earthquake Center said it’s not clear if the quake is responsible for the ship’s leak, however. The epicenter was about 260 miles (420 kilometers) southwest of Womens Bay.

... The Coast Guard confirmed the sheen in an Aug. 6 flyover, and it said a contractor is on the scene assisting with the containment.
