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 will present initial observations of the recent phases of two ongoing eruptions in the Caribbean (Montserrat) and Russia (Bezymianny).
