Title: Volcanic Ash From 1989 Mt. Redoubt Eruption, Alaska
The Alaska Volcano Observatory has recently installed a state of the art scanning electronic microscope (SEM) at its facility in Anchorage using ARRA funding. The SEM will be used to analyze volcanic deposits for their composition, texture, and other valuable information that will enable us to better understand the nature of Alaskan volcanic eruptions and improve our predictive capabilities. The image is a closeup of volcanic ash from the 1989 eruption of Mt. Redoubt in Alaska.
