Center for the Study of Active Volcanoes
The Center for the Study of Active Volcanoes (CSAV), on the Big Island of Hawaiʻi, operates out of the University of Hawaiʻi at Hilo. The Center is a training and outreach program founded by Robert W. Decker. CSAV's mission is to provide information on volcanic and natural hazards that occur in Hawaiʻi and worldwide. CSAV has been operating since 1989, and is a cooperative program of the University of Hawaiʻi at Hilo, the Hawaiian Volcano Observatory (HVO), and the University of Hawaiʻi at Mānoa (UHM).
