Landsat 8 view of Veniaminof volcano from Sept. 25, 2018 showing the intracaldera cone, ice-filled caldera, and a new ash deposit in the eastern part of the caldera. The image also shows what looks like two lobes of the lava flow melting into the snow/ice at the base of the intracaldera cone. The thermal IR image at the bottom gives a lava flow area of about 312,000 square meters. If the average thickness of the flow is 2 meters, this gives a volume of about 624,000 cubic meters as of Sept. 25, 2018. Also note that the ash deposit south of the intracaldera cone that was evident in satellite data from Sept. 9, 2018 appears to be covered with new snow.
