Decker. CSAV's mission is to provide information on volcanic and natural hazards that occur in Hawaii and worldwide. CSAV has been operating since 1989, and is a cooperative program of the University of Hawaii at Hilo (UHH), the Hawaiian Volcano Observatory (HVO), and the University of Hawaii at Manoa (UHM).
