- Abstract:
- This project is aimed at the investigation of possible trigger mechanisms for low-frequency seismic events on volcanoes. Merely the occurrence of these signals has been used as a forecasting tool on several volcanoes. Attempts in waveform modelling can explain the seismic wave propagation in and around the conduit, and a successful link has been made to derive magma properties such as pressure and gas content from seismic signals, however, the trigger mechanism, which kicks off the pressure perturbation in the first place is unknown. This research will be based on an excellent database from the ongoing eruption on Montserrat. Numerical modelling will be employed to evaluate a variety of physical trigger mechanisms, which will be tested against seismic data and other observational constraints. The final aim is to develop a model that explains the generation of a single low-frequency event as well as a prolonged earthquake swarm.
