Rat Islands

The total land area of the Rat Islands is 360.849 sq mi (934.594 km2).

However, a post-operation assessment found that many of the island's local bird populations were negatively impacted—there was a far higher-than-expected nontarget mortality.

[7] The Rat Islands are earthquake-prone as they are located on the boundary of the Pacific and North American tectonic plates.

[citation needed] The 1965 Rat Islands earthquake was one of the largest in recorded history with a magnitude of 8.7.
