Minor damage from the earthquake was recorded on both Attu and Shemya islands in the form of cracks in runways.

Damage įlooding from the tsunami caused $10,000 worth of damage on Amchitka Island. It was also observed in Peru, Ecuador, Mexico, California, Japan and eastern Russia. The tsunami had a maximum run-up height of 10.7 m on Shemya Island, 2.0 m at Amchitka Island, 1.6 m at Attu Island and 1.1 m in northern Kauai, Hawaii. This was not an aftershock, but a normal fault event within the outer rise of the subducting plate, triggered by the earlier event. The main shock was followed by an earthquake of magnitude 7.6 nearly two months later, that triggered a small tsunami. Modelling of the tsunami supports the idea that the earthquake consisted of three sub-events, related to three structural 'blocks' within the overriding plate. The pattern of energy release suggest the presence of three asperities along the plate interface, each causing a pulse of moment release. This paper presents problems associated with restoring and expanding a small boat basin at Cordova, Alaska following the Alaskan earthquake of 27. The earthquake was associated with a 600 km long rupture along the plate boundary, based on the distribution of aftershocks. The 1965 Rat Islands earthquake share common features with the 1963 Kuril Islands earthquake and the 1964 Alaska earthquake. This plate boundary, the Aleutian Trench, has been the location of many megathrust earthquakes.Ĭharacteristics Map showing the tectonics and seismicity of Alaska

The Rat Islands form part of the Aleutian Islands, a chain of volcanic islands forming an island arc, that results from the subduction of the Pacific Plate beneath the North American Plate. It had a magnitude of 8.7 and triggered a tsunami of over 10 m on Shemya Island, but caused very little damage. The 1965 Rat Islands earthquake occurred at 05:01 UTC, on 4 February (19:01, 3 February local time ).
