Volcanoes and their associated hazards can be monitored and explored through the analysis of physical signals like seismic waves, gravity changes, and ground deformation, among others. My current research focuses on the eruptive style, forecasting, and internal structure of two unique volcanic systems: Sierra Negra caldera in the Galápagos Islands (Ecuador), and the volcanoes that comprise the Garibaldi Volcanic Belt (British Columbia, Canada). Analysis of data from these particular cases will provide evidence that may unravel fundamental questions associated with common volcanic processes. Through the study of their “anomalous” behavior, the exaggerated geophysical variations during unrest at Sierra Negra and unexpected geochemical signatures at the Garibaldi Volcanic Belt, we aim to understand their current state of activity, as well as past volcanic events.
