Steve McNutt is a volcano seismologist who works part time for the Alaska Volcano Observatory. He coordinates volcano seismology research for the UAFGI, and presently supervises two PhD students, a Post-Doc, and two full time employees. His research interests include studies of source and propagation effects for volcanic tremor, low-frequency events, and explosion earthquakes; volcanic hazards assessments in Alaska, California, and Central America; and the mechanical behavior of volcanoes, including periodicity of eruptions, and the effects of earth tides, sea level variations, and tectonic stresses on triggering eruptive activity. Since July 1999 he has served as Secretary-General for the International Association of Volcanology and Chemistry of the Earth's Interior.
