|(11) Volcanic Activity Summary:||At approximately 19:15 AKDT (04:15 UTC) last night, a swarm of high-frequency earthquakes began at Little Sitkin Volcano. The continuation of this anomalous seismic activity through the night prompts AVO to raise the Aviation Color Code to YELLOW and the Volcano Alert Level to ADVISORY. No eruptive activity is currently indicated.
AVO is closely monitoring the situation and will issue further updates as conditions changes.
Little Sitkin is monitored by a 4-station seismic network as well as satellite imagery. Little Sitkin Island is located 35 km (21 mi) northwest of Amchitka and 320 km (200 mi) west of Adak in the remote western Aleutian Islands. The last eruption of Little Sitkin is questionable and may have been in the early 1900s.
