The Fisher Medal honors the memory of Professor Richard V. Fisher of the University of California Santa Barbara, who was born on August 8, 1928, in Whittier, California, and died on June 8, 2002, in Santa Barbara, California. Professor Fisher is known for his pioneering work on pyroclastic density currents. He developed models for transport and deposition based upon very carefully described stratigraphic sections and sedimentological properties of the deposits. His models were always based firmly upon his field work. The medal is given every 4 years at the IAVCEI Scientific Assembly to a scientist who has made outstanding contributions to volcanology based primarily upon field observations.
