Among the 15 islands of the Northern Marianas, Pagan Island consists of two stratovolcanoes joined by a strip of land that is less than 600 meters (2,000 feet) across at its narrowest point. The island was completely evacuated in 1981 when a large eruption forced the small Micronesian community to relocate to Saipan. Pagan, the northern volcano, is still active, and one of the more recent lava-flows has come close to the small former settlement on the west coast. To reach this lava flow one has to follow an old runway used by the Japanese during the 1940s, where the remains of several bunkers, pill boxes and planes can still be seen. A hike up the ridge will reveal a scenic view of two lakes further north. The Marianas fruit bat, the Micronesian Megapode, and the impressive coconut crab used to thrive on Pagan.
