From Wikipedia
Anatahan is a volcanic island in the Northern Mariana Islands in the Pacific Ocean, and has one of the most active volcanoes of the archipelago. Formerly inhabited, the island is currently uninhabited due to the constant danger of volcanic eruptions. Anatahan is located 60 kilometers northwest of Farallon de Medinilla and 120 km north of Saipan. It last erupted between 2007 and 2008, and also erupted in 2003.
