“In 2001, a major eruption of the Soufrière Hills volcano on the Caribbean island of Montserrat was set in motion by particularly heavy rainfall. This destabilised the volcano's dome enough for it to collapse and unleash magma within. Now it seems even typical tropical rain showers could trigger an eruption. And climate models suggest that many regions, including parts of the tropics, are likely to get wetter with climate change.

Adrian Matthews of the University of East Anglia, UK, and colleagues measured the minute-by-minute response of Montserrat's volcano after more than 200 bouts of precipitation over three years. The team found that these events, which Matthews says were typical of tropical weather, were followed by two days of increased volcanic activity.”
