Alaska Volcano Observatory reported that seismic tremor at Shishaldin has increased over the past day. Satellite and web camera observations were partly obscured by clouds over the past day but elevated surface temperatures in the summit crater were observed in several clear views. These observations are consistent with elevated unrest, but active lava effusion is less likely to be occurring.

Shishaldin volcano (Fox Islands, USA) - Smithsonian / USGS Weekly Volcanic Activity Report for 6 November-12 November 2019 (New Activity / Unrest)
AVO reported that the eruption at Shishaldin continued at variable levels during 5-12 November. Periods of high-amplitude tremor during 5-6 November were likely related to increased lava effusion and fountaining, though weather clouds prevented visual confirmation. Intermittent advancement of active lava flows and lahars on the N flank were confirmed in RADAR data, and by 7 November the lava flow was 1.3 km long and the debris flow runout was 5 km. ... Read all

Shishaldin volcano (Alaska, USA) activity update: lava flow on the northwest flank has increased in length and developed two branches
AVO reported that lava is overflowing the summit crater and the lava flow on the northwest flank has increased in length. Satellite data on Sunday afternoon show that the flow has developed two branches, each extending for about 1000 meters (0.62 miles). Volcanic debris flows (lahars) have also increased in length and now extend as far as 2 km (1.2 miles) on the north and south flanks. ... Read all
