Seismicity at Little Sitkin Volcano remains above background. Satellite images were cloudy to mostly cloudy in the past week. Little Sitkin volcano occupies Little Sitkin Island in the western Aleutian Islands, and is within the Aleutian Island National Wildlife Refuge. The active stratovolcano rises 1188 m (3898 ft) in the center-northeastern part of the island. The island is 330 km (200 mi) northwest of the community of Adak, 377 km (234 mi) southeast of Attu, and 2173 km (1350 mi) southwest of Anchorage, Alaska. Little Sitkin has no confirmed historical eruptions, although eruptive activity near the turn of the last century seems probable based on vegetation cover of the youngest-looking lava flows. Three long-lived fumarolic and hot springs areas are known including a cluster of boiling, acidic pools on the west flank of the volcano.
