Caption:Aerial view of Veniaminof volcano in eruption at about 11:30 am on September 7, 2013. Photograph by Joyce Alto. White water vapor clouds rise from regions where hot lava is encountering snow and ice. A gray-brown ash column rises in the background from the active vent. Note the ash-darkened icefield within the summit caldera.

Caption:Ash-rich eruption from the intracaldera cone at Veniaminof, August 18, 2013. The gray-brown cone of debris at the base of the eruption column has been built by this type of activity since about June 13. Photo taken by Game McGimsey, AVO/USGS. Overflight to Veniaminof co-sponsored by the National Geographic Society.

Caption:Veniaminof volcano in eruption, August 18, 2013. Pulses of ash and ballistics erupt from the intracadera cinder cone. Two streams of lava flow down the east flank into an ice cauldron to produce roiling steam clouds. The lava flows are pouring from vents located below the crater rim, the highest (left in this image) of which likely marks the level of a lava lake within the cone. Photo taken by Game McGimsey, AVO/USGS. This overflight of Veniaminof was co-sponsored by the National Geographic Society.

Caption:Veniaminof volcano in eruption, August 18, 2013. A steady stream of molten lava flows down the east flank of the intracaldera cinder cone, advancing into an ice cauldron to produce a roiling steam plume. Photo taken by Game McGimsey, AVO/USGS.

Caption:Veniaminof volcano in eruption on August 18, 2013. Molten lava is hurled skyward from the active intracaldera cinder cone. Ballistics such as these were observed rising several hundred meters above the vent. Photo taken by Game McGimsey, AVO/USGS.

Caption:Veniaminof volcano in eruption, August 18, 2013. Ash billows from the intracaldera cinder cone as molten lava streams from two separate vents high on the east flank of the cone. The level of the highest lava source likely marks the level of a lava lake within the active crater. Photo taken by Game McGimsey, AVO/USGS. This overflight of Veniaminof was co-sponsored by the National Geographic Society.

Caption:Aerial view of the eruption at Veniaminof's intracaldera cone, August 18, 2013. This cone rises about 1000 feet above the surrounding icefield. It has been intermittently erupting lava, ash and steam since June 13, 2013. This photo shows the incandescent, orange stream of molten lava emerging from the active cone. Steam billows from the pit at the base of the cone where the lava encounters and melts ice and snow. A small, ash-rich plume rises just above the vent producing a diffuse ash cloud that drifts downwind. In the foreground, round white patches probably represent ballistic impact craters. Photo taken by Game McGimsey, AVO/USGS. This overflight of Veniaminof was co-sponsored by the National Geographic Society.

Caption:A small puff of ash emerges from the active cone inside Veniaminof caldera on August 18, 2013. A beautiful fan of lava flows active earlier in the summer descends onto glacial ice producing white steam clouds and depressions where melting has occurred. The surrounding glacier is darkened by recent ash fall.

Caption:Aerial view of the erupting intracaldera cone at Veniaminof, August 18, 2013. This photo shows new lava flows produced since the eruption started on June 13, 2013. These flows (here roughly 3000 feet in length) have descended the southwest flank of the cone and traveled onto the ash-covered snow and icefield. Melting of the snow and ice has created the depressions beneath the young flows. A small puff of ash rises from the active vent. Photo taken by Game McGimsey, AVO/USGS. Overflight to Veniaminof co-sponsored by the National Geographic Society.

Caption:Veniaminof volcano in eruption, August 18, 2013. Pulses of ash rise from the intracaldera cinder cone. The active vent is nestled within and atop a previously constructed cinder cone. Note the cloud of ballistics immediately above the dense ash plume rising from the vent. Photo taken by Game McGimsey, AVO/USGS. This overflight of Veniaminof was co-sponsored by the National Geographic Society.
