Seismic and Infrasound Studies

Seismic and infrasound studies provide many of the most insightful and quantitative insights into internal structure and eruption physics of volcanoes. Infrasonic research at Mt. Erebus is currently being conducted by Jeff Johnson and Rick Aster at NMT.

Visit the infrasound site of professor Jeff Johnson and his students to learn more about infrasonic monitoring of active volcanoes.
