Between the Volcano and the Deep Blue Sea: Tales from Montserrat (Part 2)
View of Soufrière Hills Volcano from Saint George's Hills, May 16th, 2024.

In 1995, the Caribbean Island of Montserrat was shaken by the beginning of one of the most significant volcanic eruptions in recent history: one that profoundly changed the natural, social and economical landscape of the country. Three decades later, Soufrière Hills Volcano and its legacy of destruction still shape the lives of Montserrat’s people. Last October, we took you on the first half of ou ...[Read More]

  Across the Arctic lies evidence for a massive past volcanic event, called the High Arctic Large Igneous Province (HALIP). This ancient volcanic event is particularly unusual in that it appears to have lasted for over 50 million years. Could a single deep-seated mantle plume cause such wide-spread and long-lived volcanism? In a recent study published in the journal G-cubed (Heyn et al., 2024 ...[Read More]
