Kasatochi Island 2009 topography

The 2008 eruption of Kasatochi volcano caused major topographic changes to Kasatochi Island, making all prior topographic maps and data obsolete. The topographic map and data presented here are derived from stereoscopic satellite images acquired on April 18, 2009. Subsequent topographic data has not been acquired, although there has been substantial topographic modification to the island, particularly to the shoreline, since these data were acquired.
