Stephen McNutt

Stephen McNutt is Professor of Volcano Seismology at the University of South Florida's School of Geosciences, where he coordinates volcano seismology research. Previously affiliated with the Alaska Volcano Observatory (1991-2012) and California Division of Mines and Geology (1984-1991), his research examines volcanic tremor, hazard assessment, earth tide effects, infrasound, and volcanic lightning.

He earned his Ph.D. from Columbia University (1985) and B.A. from Wesleyan University (1977). McNutt currently supervises PhD students and has published extensively on eruption processes and monitoring techniques. Professional service includes former Secretary-General for the International Association of Volcanology (1999-2007).

Research integrates seismic, infrasound, and lightning detection systems to analyze eruption dynamics. Recent investigations focus on swarm seismicity patterns and the 2022 Hunga Tonga eruption mechanisms. Fieldwork spans Alaska, Central America, and the Pacific Rim.
