In 2001 the Seismic Research Centre (SRC) initiated a geothermal monitoring programme, as part of an integrated volcanic monitoring programme. Instituted to geochemically characterize hydrothermal systems associated with volcanoes of the Lesser Antilles, the programme also established baseline levels of activity from which changes in volcanic activity can be detected. Ms. Joseph was intimately involved in the geothermal monitoring efforts and chose to conduct the research as a PhD project in 2003. The PhD thesis examined the “Geochemistry of Geothermal Systems in Saint Lucia and Dominica, Lesser Antilles: Implications for Volcanic Monitoring”. ![]() The results of geothermal monitoring in the islands of Saint Lucia and Dominica have successfully demonstrated that it is a valuable tool that can be utilized with other volcano monitoring techniques (seismicity and ground deformation). The information it provided has given insight into changes in temperature and mineralogy of hydrothermal fluids associated with volcanic systems that can provide scientists with precursory indicators of magmatic inputs.
