The Secret Lives of 'Quiescent' Volcanoes - Clues from Volcano Seismology
Dr. Diana Roman, Carnegie Institution of Washington, Department of Terrestrial Magnetism
Magmatic processes generate a wide range of seismological phenomena, and a dramatic increase in seismicity is often one of the earliest observable precursors to a volcanic eruption. With the spread of permanent monitoring networks on volcanoes in recent decades, it has become evident, however, that many episodes of volcano-seismic unrest do not culminate in eruptions, complicating efforts to understand the processes driving seismic activity in volcanic settings. This presentation will focus on the unique challenges of conducting seismology research on volcanoes, and will highlight several examples of volcano-seismic unrest at 'quiescent' volcanoes in Alaska, Montserrat, and Nicaragua.
