St. Vincent - Seismicity
St. Vincent lies in an area of the Caribbean which has a low seismic hazard. Volcanic earthquakes have been associated with most of the explosive eruptions in the historic past. The only documented effusive eruption of the historic past was aseismic (Aspinall, et al., 1973). Premonitory earthquake activity preceding a violent eruption has varied from a few days to months and even years (Anderson and Flett, 1903, Shepherd, et al., 1979). The value of such activity as an alarm is, however, limited since there have been numerous occasions in which earthquakes occurred with no ensuing eruptions.
