Caption:MODIS satellite image showing resuspended Katmai 1912 ash being blown southeast over Shelikof Strait, March 12, 2015. This ash is being blown not from the Valley of Ten Thousand Smokes, but rather from the lower Katmai river valley deposits. We acknowledge the use of Rapid Response imagery from the Land, Atmosphere Near real-time Capability for EOS (LANCE) system operated by the NASA/GSFC/Earth Science Data and Information System (ESDIS) with funding provided by NASA/HQ.

Caption:Composite Landsat-8 image of Veniaminof Volcano collected on February 28, 2015. The grey scale base image is from the 15-meter-resolution "Panchromatic" band that records visible light. Superimposed onto it (in color) are short-wave infrared data that are sensitive to high temperatures. These data show high surface temperatures, expressed as radiance values (a measure or thermal emission), confined to the summit crater of the intracaldera cone. These areas of elevated surface temperatures are typical for Veniaminof during non-eruptive periods. The surface expression of the lava flows produced during the 2013 eruption are seen as depressions in the snow cover on the south and east sides of the cone. A faint shadow from steam emissions can be seen over the summit icefield to the southeast of the cone, although the emissions themselves are not readily visible.

Caption:Ash from Shiveluch volcano in Russia’s Kamchatka peninsula crossed the Bering Sea Saturday, February 28, 2015, and caused flight cancellations in western Alaska. The ash cloud is the linear blue feature seen in this image derived from NOAA satellite data. The ash cloud was tracked by the Tokyo and Anchorage Volcanic Ash Advisory Centers, which are responsible for forecasting the movement of potentially hazardous ash cloud. These forecasts provide the details for the issuance of warning messages. In Alaska, the National Weather Service Alaska Aviation Weather Unit issues ash warning messages.
