Location: 19.7N, 145.4E

Elevation: 891m (2,923

Area 7 sq. km Altitude 891 m

Island type: high volcanic cone, radially dissected

Asuncion is a stratovolcano. The most recent confirmed eruption was in 1906. Volcanologist visited Asuncion in 1992 and observed active fumaroles. A view of the west flank of Asuncion clearly shows the rocky shore, palm-covered slopes and the summit cloaked in clouds. An island of approximately 2.8 square miles, it is located 259 nautical miles north of Saipan. The volcano rises steeply as an almost perfect cone. White smoke occasionally emerges from the top and slopes. Lava has steamed down the mountainsides giving it a black surface. Shrubs and a few trees can be seen in some places. There is a landing beach at the southwest end of the island. Asuncion is uninhabited.

Natural threats: volcanic threats, cyclones.

Human impact: coconut plantations on lower slopes, visited occasionally

Ecosystems: rain forest in ravines, grasslands and fernlands on upper Slopes.

Special features: active volcano; best forest development in northern islands, of considerable conservation interest; proposed as marine sanctuary.
