Caption:Pavlof Sister, June 7, 2016. This stratocone lies just northeast of Pavlof Volcano, and although Pavlof Volcano has frequent modern eruptions, Pavlof Sister is more eroded and has no definite historical eruptions. Photo credit Max Kaufman, AVO/UAFGI.

Caption:Avalanche at Iliamna, May 22, 2016. Photo taken from near Homer, AK, courtesy of Dennis Anderson, Night Trax Photography. AVO detected seismic and pressure sensor signals associated with a large avalanche on the flank of Iliamna Volcano around midnight Alaska Daylight Time on May 21. (07:58 UTC May 22, 2016). Avalanche events are somewhat common at this volcano. The most recent prior avalanche event was in November 2013. The seismic signals from the avalanche were observed on volcano monitoring networks throughout Cook Inlet and as distant as the Katmai region 250 km (155 miles) away.

Caption:Landsat-8 true color satellite image collected on May 23, 2016 showing the source and deposit extent of a mixed ice, snow and rock avalanche covering part of Red Glacier on the east flank of Iliamna Volcano. The avalanche began shortly before midnight on May 21, 2016 (AKDT) and was detected in seismic and pressure sensor data at sites throughout Cook Inlet and the northern Alaska Peninsula. The deposit covers about 7.2 square kilometers (2.75 square miles).

Caption:Landsat-8 data from 15 May 2015 at 22:17 UTC (2:17 PM AKDT) show robust steaming and high temperatures in Cleveland Volcano's summit crater (in the shortwave IR), indicating continued unrest. The high-temperature feature is visible in this image as a red pixel. Robust steaming observed extending to the west and seen as a shadow on the lower meterological cloud deck. Shortwave IR has very little reflectance from snow, which is why Cleveland appears blue.

Caption:AVO personnel use this FEI Quanta 200 electron microscope for rapid analysis of volcanic ash. The microscope is equipped with secondary electron (SE) and backscatter electron (BSE) sensors, as well as a highly sensitive silicon drift detector energy-dispersive X-ray spectroscopy (SDD EDS). This instrument is well suited for acquiring high-resolution images of micron-size ash particles and for identifying mineral phases. The electron microscope is part of the Advanced Instrumentation Laboratory of the University of Alaska Fairbanks https://www.uaf.edu/ail/.
