The active Russian volcano Bezymianny in Kamchatka shows an ongoing flow from a vent on the side of the volcano on Dec. 28, 2000. This image is a composite of a Spaceborne Thermal Emission Radiometer image showing the volcano's topography (blue) and a thermal infrared image showing the 'hot spot' (red) in great detail. The satellite's ability to sense fine-scale heated surfaces is providing never-before seen views of active volcanic eruptions. These observations provide a detailed look into the eruptive history. Lava flows, hot mudflows, and other details of eruption activity that cannot be seen using other techniques are revealed.
