Caption:October 2014 rockfall from high on the eastern headwall of Iliamna Volcano, from below the NE fumaroles. The debris ran about 2km down the upper Red Glacier. The slide happened early UTC on Oct 3 2014. Reported with help from Jackie Caplan-Auerbach and Rick Wessels. photo taken from Ninilchik AK.

Caption:Seismic signal from October 2014 rockfall off the eastern headwall of Iliamna Volcano, from below the NE fumaroles. The debris ran about 2km down the upper Red Glacier. The slide happened at 0316 UTC on Oct 3 2014 (7:16 pm Oct 2nd local time). Plot shows 90 sec of seismic data. The waveforms have the classic emergent onset and taper of a rockfall and subsequent mixed rock and snow slide on a glacier. Reported with help from Jackie Caplan-Auerbach and Rick Wessels.

Caption:Fumarolic emission from Chiginagak volcano on the Alaska Peninsula. This is a long-lived side of steam and volcanic gas emission, but in late September 2014 there was an apparent increase in temperature and perhaps flux from the fumarole. This resulted in a more robust cloud, visible from space by satellite, detectable quantities of sulphur dioxide, and what appears to be a melt channel in the surrounding glacier. No regional earthquakes have been detected, although AVO does not maintain any seismic stations near this volcano and very small events may have gone unnoticed.

Caption:Annotated 24-hour webicorder display for station CKN at Mount Spurr Volcano on September 10, 2014. During a daily check of seismic data as the AVO duty seismologist, AVO geophysicist John Lyons noted the protracted, sudden onset signal that occurred just after 11:21 local time. He interpreted this as a likely outburst of water from beneath one of the glaciers that flow southward off Mount Spurr. AVO seismologists have seen other examples of this type of long-duration signal when high-discharge events have been seen in the field. Note how different this appears from a typical regional earthquake (at top) and the twice-daily station calibration pulses (at left).

Caption:Part of a ~6 m (20 feet) thick section of ash and lapilli falls from Cleveland and nearby volcanoes, exposed in a gully on the southeast flank of the volcano. We will be analyzing some of the ashes and soils from this section to begin to understand eruption frequency in the Islands of Four Mountains. Measuring tape is 1 m 3.3 feet) long. Photo taken during the 2014 field season of the Islands of Four Mountains multidisciplinary project, work funded by the National Science Foundation, the USGS/AVO, and the Keck Geology Consortium.

Caption:Summit caldera of Herbert volcano in the Islands of Four Mountains (IFM) Aleutians. This rarely visited and little known volcano shows evidence of youthful eruptions, although none are known in historic time. The small patch of wasting glacial ice at lower left has receded in the last few decades to expose active fumaroles (lower right, light colored patch of ground). Photo taken during the 2014 field season of the Islands of Four Mountains multidisciplinary project, work funded by the National Science Foundation, the USGS/AVO, and the Keck Geology Consortium.
