Can lahars or mudflows be generated during and after this eruption?
Yes. There has been significant ashfall across mainland St. Vincent. With rain, ash deposits will be swept into rivers and streams forming lahars or mudflows. These flows usually have a high temperature and can carry large amounts of volcanic debris. These can happen months after the eruption has ended.
