Monitoring - Seismology
One of the most effective ways of monitoring volcanoes is seismology. In case of a renewal of volcanic activity, magma will tend to induce cracks on its way towards the surface. These cracks will, in turn, induce some high-frequency seismic activity which can be detected by our seismic network which is composed of Broadband and Short-Period instruments. Movement of magma and pressurized fluids (e.g., gas) close to the surface tend to produce long period event which can be detected by broadband seismometers. Data are collected continuously and transmitted automatically to SRC in Trinidad via the internet. They are then processed to obtain information about their source (nature of the source, location and magnitude – for the short-period events).
