Why should you care about hydrothermal alteration in volcanic systems? When people think of volcanoes, they imagine large, devastating eruptions and lava streams gushing from the summit of an edifice.

La Soufrière de Guadeloupe is an andesitic stratovolcano located in the southern part of Basse-Terre, within the Guadeloupe archipelago (Eastern Caribbean). It towers over the towns of Sainte-Claude and Basse-Terre. Nearly 50 years ago, this region faced severe consequences from a phreatomagmatic eruption, forcing the evacuation of 80,000 people. Since then, the volcano has been regularly monitore ...[Read More]
