The hazard level applying to Soufrière Hills volcano on Montserrat was raised on 10 December by NDPRAC, the National Disaster Preparedness and Response Advisory Committee, to the second-highest level of 4 (click here for an explanation of the extremely complicated Montserrat hazard level system). Pyroclastic flow activity associated with the growth of the lava dome has increased in intensity, with flows reaching a point 3.5 km from the lava dome. Still larger pyroclastic flows are a possibility: a partial dome collapse ‘could involve several million cubic metres of material’.

For more information see this bulletin on the Montserrat Volcano Observatory’s information-rich but very cumbersome website.
