Iliamna

Debris flow/mudflow/landslide/lahar

Caption:	Iliamna volcano debris avalanche photo by Dennis Anderson, taken on Diamond Ridge near Homer. AVO detected seismic and pressure sensor signals associated with a debris avalanche on Red Glacier on the flank of Iliamna Volcano around 4:05 p.m. Alaska Daylight Time on Thursday, June 20, 2019 (00:00 UTC on June 21, 2019). Avalanche events are somewhat common at this volcano. The most recent prior to last week's occurred in April 2019. The seismic signals from the avalanche were observed on volcano monitoring networks on Illiamna and Redoubt volcanoes. Infrasound from this slide was detected with pressure sensors in Dillingham, Fairbanks, and those on the EarthScope Transportable Array. The avalanche and subsequent seismicity and infrasound are not considered to be indicative of volcanic unrest.

Iliamna

Avalanche, Debris flow/mudflow/landslide/lahar, Glacier

Caption:	Rockslide on Iliamna volcano on 6/21/2019. This image was taken around 11:00 am on 6/22/2019 by Dennis Anderson from Diamond Ridge NW of Homer using a tablet at the eyepiece of some 11x80 binoculars with a 4.5 degree field of view. This might have occurred sometime in the past 12-48 hours as Illiamna was obscured by clouds most of yesterday.

Iliamna

Debris flow/mudflow/landslide/lahar

Caption:	Photo of Red Glacier avalanche that occurred on 6/21 ~00:05 UTC (6/20 ~4:05 pm AK). Description from the photographer: "attached pics from a fly by this past Friday evening. The slide appeared a few days old at that point, and seemed to originate near the summit. The slide & debris are visible from across the inlet now as well. Debris field approx 2+ miles wide & the toe. Pretty impressive slide altogether!"
