摘要: We have used a digital model of the topography Montserrat, simple mathematical gravitational flow and some assumptions way in which next eruption will develop to create map volcanic hazards from Soufriere Hills Volcano. This has been done using an image processing computer simulate deposits produced by pyroclastic flows. technique advantages over more traditional cartographic methods spatial precision, rapid computation multiple models explicit nature physical used. Volcano is small andesitic volcano characterized cluster summit domes apron mudflows upon several thousand people now live. Most flanks were covered series eruptions 24000 16000 BP, though there evidence that dome growth flows occurred since. The modelling constrained field previous eruptions. Although not good enough individual units, cumulative can be From deposit we created new type specifically for emergency planning. sequential hazard zone attempts portray regions would at during successive stages start whose energy release was increasing with time.
