Caption:Sunset view of erupting Veniaminof volcano on the Alaska Peninsula, July 9, 2013. Photograph from the Sandy River about 20 miles west of the volcano. A dark ash column rises from the intracaldera cone at an elevation of about 7000 feet. During the time of this and other photos from the Sandy River in June and July, observers reported clearly hearing rumbling and explosions. Veniaminof is an ice-clad, andesite and dacite stratovolcano about 84 cubic miles in volume. Two Holocene caldera-forming eruptions are recorded in extensive pyroclastic-flow deposits around the volcano/ It is one of the largest and most active volcanoes of the Aleutian Arc.

Caption:Three-minute video clip of erupting Veniaminof volcano in beautiful evening light, July 9, 2013. Movie was taken with a small hand held camera about 20 miles west of the volcano on the Sandy River. It begins with zoomed in views of discrete, closely spaced bursts of ash feeding a steady eruption cloud. Later, the photographer zooms out and you can see the caldera walls for context. Note that the discrete bursts produce puffs of ash which drift downwind; aerial views of the caldera show dark rays of ash extending from the cone, reflecting fallout from the cloud. The active lava flows are not visible in this view from the west.

Caption:Composite satellite image of Veniaminof volcano collected by the EO-1 Advanced Land Imager on July 4, 2013. This image is a composite of the short-wave infrared data (to show thermal emissions from the active lava flow) overlain onto a visible wavelength image. The active lava flow is shown in shades of yellow and orange, and extends southward from the vent. Thin deposits of volcanic ash are seen on the snow and ice, as radial spokes that form when ash is emitted under changing wind direction.

Caption:False-color composite image of Cleveland volcano collected by Landsat-8 on July 3, 2013. This image is a composite of the short-wave infrared data (to show thermal emissions) and the imaged is sharpened using visible wavelength data. High temperatures in the summit crater as shown as pink colors that are visible through a wispy steam cloud. These hot temperatures are typical for Cleveland volcano, which shows continued signs of low-level unrest.

Caption:View of the ash-darkened, erupting intracaldera cinder and spatter cone of Veniaminof. Picture taken June 28, 2013, from the Sandy River on the Bering Sea side of the volcano. Cone Glacier descends from the 6-mile-wide, ice-filled caldera at the top of the volcano. The elevation of the top of the erupting cone is about 7000 feet.

Caption:High resolution satellite view (Digital Globe WorldView 1) showing several new lava flows covering the south flank of the active intracaldera cone in Veniaminof caldera. The longest flow in this view is about 750 m (2460 ft) from the incandescent summit to the toe of the flow on the icefield. Dark ash covers much of the NW flank of the cone and the icefield.

Caption:Photo of Pavlof Volcano taken on June 25, 06:30 AKDT from Sand Point, Alaska. This image shows an ash cloud and incandescence at the summit. Incandescence is indicative of lava fountaining and is coincident with a distinct increase in seismic activity on the morning of 6/25/13.

Caption:Nighttime (1300 UTC, 05:00 AKDT, on 24 June) AVHRR thermal IR minus mid IR enhancement shows an extensive, water-rich plume emanating from the intracaldera cinder cone of Veniaminof . The plume likely results from lava interacting with snow and ice and is mainly steam, but may have contained minor ash.

Caption:Topographic map of Veniaminof, showing the margin of the caldera (red dashed line) and the active cone within the caldera (black circle). The current eruption (June 2013) has produced a small lava flow (less than 1/2 mile long as of June 18) down the flank of the active intra-caldera cinder cone. Veniaminof's caldera is 5-6.8 miles in diameter.
