St. Vincent - Monitoring

Before the twentieth century the potentially destructive capacity of this volcano was not fully realised. No monitoring system was in place and scientific knowledge of the system was very limited. Seismological studies at the Soufrière volcano began in 1953 (Figure 5) with the establishment of the Seismic Research Unit and since then has evolved to its present state. Presentaly, monitoring of the Soufrière volcano is carried out by the Seismic Research Unit assisted by a small local unit (called the Soufrière Monitoring Unit) that operates from the Ministry of Agriculture in Kingstown. The monitoring network consists of five seismic stations, 8 GPS stations and several dry tilt sites. Seismic data are transmitted from field sites to the Belmont Observatory operated by the Soufrière Monitoring Unit. The data are then accessed from Trinidad via the internet. Regular observation is made at the summit of the volcano and measurements taken of lake and fumarole temperature and observed changes in the state of the volcano noted. A detailed description of the evolution of the monitoring network can be found here.
