Abstract:

Ii is a well known fact that one of the more accurate methods to predict a possible volcanic eruption is through seismic monitoring. The ideal way to approach the monitoring of volcanoes is by complementing and supporting the seismic data with other types of data, such as infrasound, soil deformation (measured by GPS), geochemistry and mineral variation studies in the hydro-thermal system around the volcano, heat measurements of the ash plumes and the volcanic body, etc. However, what if the resources are not enough and there is just a single seismic station in the vicinity of the volcano? Is it possible to record the seismic activity with just one sensor and obtain acceptable locations and confident parameters of the events recorded? This study will discuss how some of the IMS seismic stations that are close to active volcanoes (or potentially active), can be used for early warning in case of poor or no monitoring in the region. Real cases, from around the globe, will be used to support the work in this study.
