Caption:These figures show a high resolution image of the Veniaminof eruption that was acquired by the WorldView-2 satellite on November 5. The image is shown in false color (near-infrared, red, and green bands) to highlight the lava channel. The left figure shows the continuous ashy plume that drifted northeast throughout the day on November 5. There is also a fresh tephra deposit on the snow that is likely from the previous day when the plume was heading east. In the close-up of the lava flow on the right, it is possible to see the active lava channel along the western flow margin that is feeding the flow front, where there is a small steam plume. The active flow length along the channel is ~1.1 km and the channel width ranges from 10 meters near the vent to 60 meters distally. The newer flows are snow-free, while the older eastern lobe appears to have a dusting of snow on top. Ice continues to collapse around the flow front from melting.

Caption:When erupting, all volcanoes pose a degree of risk to people and infrastructure, however, the risks are not equivalent from one volcano to another because of differences in eruptive style and geographic location. Assessing the relative threats posed by U.S. volcanoes identifies which volcanoes warrant the greatest risk-mitigation efforts by the USGS and its partners. This update of the volcano threat assessment of Ewert and others (2005) considers new research in order to determine which volcanic systems should be added or removed from the list of potentially active volcanoes, updates the scoring of active volcanoes, and updates the 24-factor hazard and exposure matrix used to create the threat ranking. The full report is available at https://pubs.er.usgs.gov/publication/sir20185140 .

Caption:This high resolution ESA Sentinel-2 image of Veniaminof from Saturday, 6 October 2018, shows continued lava effusion and a plume with a thin tephra deposit beneath headed off to the north. The eastern flow front is producing the strongest steam plume and the ice is collapsing around the flow front margins. This image is grayscale showing brightness in band 4 (red wavelengths), rather than an RGB composite.

Caption:This false color ESA Sentinel-2 image of Veniaminof from Saturday, 6 October 2018, shows continued lava effusion and a plume with a thin tephra deposit beneath headed off to the north. The flow remains ~1 km in length with the most active front on the east side, which has a SWIR (short wave infrared) anomaly extending all of the way to the flow front. A branch in the channel feeding the western lobes appears to be active, as well, but without any SWIR anomaly near the flow front, suggesting that this western branch is less active. The eastern flow front is producing the strongest steam plume.
