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 an Advanced Spaceborne Thermal Emission and Reflection
Radiometer (ASTER) image showing the volcano's topography (blue) and a
thermal infrared image showing the "hot spot" (red) in great detail. ASTER is the "zoom lens" aboard NASA's Terra
ASTER'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. Michael Ramsey, of the University of
Pittsburgh, presented on May 30, 2001, at the American Geophysical Union's (AGU) Spring meeting ASTER's initial observations of the
recent phases of two ongoing eruptions in the Caribbean (Montserrat) and
