جزر الفئران ( Rat Islands ؛ ألوت: Qax̂um tanangis,[1] روسية: Крысьи острова) are a group of American volcanic islands في جزر ألوشن في جنوب غرب ألاسكا، بين جزيرة بولدير و الجزر القريبة group to its west, and Amchitka Pass ومجموعة جزر أندريانوف إلى الشرق منها. The largest islands in the group are, from west to east, كيسكا، كيسكا الصغيرة، Segula, هاواداكس or Kryssei, Khvostof, Davidof, Little Sitkin, Amchitka، و سمي‌سوپوتشنوي. The total land area of the Rat Islands is 360.849 sq mi (934.594 km2). None of the islands are inhabited.

جزيرة هاواداكس

الاسم جزر الفئران is the English translation of the name given to the islands by Captain Fyodor Petrovich Litke in 1827 when he visited the Aleutian Islands on a voyage around the world. The islands are named so because rats were accidentally introduced to Rat Island in about 1780.[2] اعتبارا من 2009, after a government-funded eradication program, Rat Island is believed to be rat-free;[3] it was renamed Hawadax Island in 2012. 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.[4] An internal U.S. Fish and Wildlife Service Office of Law Enforcement investigation revealed that several laws may have been violated.[5]

The Rat Islands are earthquake-prone as they are located on the boundary of the Pacific and North American tectonic plates.[بحاجة لمصدر] The 1965 Rat Islands earthquake was one of the largest in recorded history with a magnitude of 8.7.[6]
