The Secret Life of Quiescent Volcanoes
Diana Roman's (DTM) talk discussed eruptions, while dangerous and captivating, represent only a small fraction of the geological activity that occurs at Earth's volcanoes. The spread of geophysical monitoring networks on potentially active volcanoes in recent decades has highlighted a wide spectrum of magmatic unrest beneath apparently 'quiescent' volcanoes.
We will explore different types of non-eruptive volcanic unrest through a survey of case studies and consider the implications for eruption forecasting and for our overall understanding of volcanic processes.
Roman is interested in the mechanics of how magma moves through the Earth's crust, and in the structure, evolution, and dynamics of volcanic conduit systems. Most of her research focuses on understanding changes in seismicity and stress in response to the migration of magma through volcanic conduits, and on developing techniques and strategies for monitoring active or
restless volcanoes through the analysis of high-frequency volcanic seismicity. Additional research interests include source processes of background seismicity at quiescent volcanoes, tectonic and 'cryptovolcanic' microearthquake swarms, and the nature of volcanic intrusions ('failed' eruptions).
