I didn't realize that Soufrière Hills volcano on Montserrat ( https://en.wikipedia.org/wiki/Soufri%C3%A8re_Hills ) and La Soufrière volcano on St Vincent ( https://en.wikipedia.org/wiki/La_Soufri%C3%A8re_(Saint_Vincent) ) were two different volcanoes. There are also two other Caribbean volcanoes with Soufrière in their names. This makes sense, because it appears that soufrière is french for sulfur
