Ringkasan geologi
Sarigan volcano forms an irregular 3-km-long island consisting of a low truncated cone with a 750-m-wide summit crater that contains a small ash cone. The most recent eruptions produced two lava domes from vents above and near the south crater rim. Lava flows from each dome reached the coast and extended out to sea. The northern flow overtopped the crater rim on the N and NW sides. The sparse vegetation on the flows indicated to Meijer and Reagan (1981) that they are of Holocene age.

The island has been sparsely populated, but in modern times has been uninhabited due to volcanic activity. It is currently a nature preserve.
