Sarigan

Stratovulcano · United States · 494 m

The 3-km-wide Sarigan volcano is seen here from the E during a 2003 NOAA expedition to the Marianas Islands.The cone has a 750-m-wide summit crater that forms the flat area to the right and it contains a small cone. More recent eruptions produced two lava domes from vents on and near the S crater rim, forming the island's high point at the left part of the summit. Holocene lava flows from the dome complex formed the peninsula to the far left.

Sintesi geologica

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.
