Caption:Cleveland volcano remains active. In this perspective Landsat-8 satellite image view, shortwave-infrared data is overlain on visible wavelength data. Colors show the location of elevated surface temperatures in the summit crater due to the presence of a small lava dome or plug.

Caption:401 earthquakes were located at Geyser Bight in 2014. The largest earthquake was a magnitude 3.1 (shown by the star), occurring on the eastern flank of Recheshnoi within a swarm of activity in September 2014 (yellow symbols). Two identified swarms occurred in the hot springs area in October (orange symbols) and late November (red symbols). Earthquake hypocenters are colored by time of occurrence - see scale at bottom of image.

Caption:Real-time seismic amplitude (RSAM) time series for Veniaminof seismic station VNWF, located on the lower southwestern flank of the caldera. Plot runs from June 2013 through December 2014 and shows the seismic energy release associated with 2013 eruption and the gradual decline in seismicity beginning in late October 2013. Several episodes of increased low-frequency events and tremor bursts occurred from mid-July to end of the year (e.g. July 15, Oct. 8, and Dec. 18); however, these were not associated with any eruptive activity and may have reflected continued degassing of the system.

Caption:Clear weather conditions last week prompted a number of keen-eyed observers to share photos of fumarolic plumes at the Katmai group volcanoes. This is a photograph of Griggs volcano taken through a spotting scope from King Salmon, Alaska, about 60 miles northwest of the volcano. Circle highlights a vigorous, long-lived, high-temperature fumarole on the southwest flank of the volcano. It has been said that on calm days, the roar of this fumarolic jet can be heard from the valley floor.

Caption:NASA EO-1 Advanced Land Imager image high temperature flowage deposit on the northwest flank of Pavlof Volcano. This shortwave infrared image is sensitive to very high temperatures. This flowage deposit likely contains both new lava and hot rock debris, but the distribution has not yet been determined. The deposit extends for about 3.3 miles (5.4 km) from the vent.
