Sarigan volcano forms a 3-km-long, roughly triangular island. A low truncated cone with a 750-m-wide summit crater contains a small
ash cone. The youngest 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, forming irregular shorelines. The northern flow overtopped the crater rim on the north and NW sides. The sparse vegetation on the flows indicates they are of
Holocene age. From the
