Project Title: Seismic source mechanism at active volcanoes

Supervisors: Dr. Francesca Martini, Dr. Gareth O'Brien and Prof. Christopher J. Bean

Funding Agency: Science Foundation Ireland

Project Description: The role of fluids in generating seismicity at active volcanoes has been well established, but the actual physical processes have not been fully determined. Recent numerical studies have shown that accounting for near-surface structure and including records from stations at the volcano summit into the moment tensor inversion of volcanic signals is fundamental to obtain reliable results. If not, path effects leak into the source solution, leading to erroneous source geometries and mechanisms. This study proposes an innovative field experiment that considers those factors on an easily accessible but restless volcano in Central America, providing a template for volcanic seismic surveys. The data collected under a tightly controlled geometric configuration will be inverted to obtain one of the first reliable data inversion studies, opening up new avenues in our understanding of volcano source processes. Participation in fieldwork at Turrialba volcano, Costa Rica will form part of the project.
