Summary:The eruptive activity of Mt St Helens since 1980 and the successful monitoring programme of the US Geological Survey are summarized. There have been no large explosive events since October 1980, the subsequent eruptions being merely dome building. Monitoring includes the study of seismic activity, deformation, gas emission and thermal patterns. The aim of the monitoring programme is to provide timely warning of eruptive and related hazards in the form of factual statements, non-specific forecasts and comparatively specific predictions and also to exchange information with scientists studying active volcanoes in other countries.-M.J.B.
