Melting glaciers could trigger more explosive eruptions globally
Melting glaciers may be silently setting the stage for more explosive and frequent volcanic eruptions in the future, according to research on six volcanoes in the Chilean Andes.
Summary
Studies of six Chilean Andes volcanoes suggest a link between glacial melt and increased volcanic activity. As glaciers shrink, the reduced weight on the Earth’s crust allows magma chambers to expand and potentially trigger eruptions. This isn’t about overall global warming directly, but rather the localized weight changes specific to areas with significant glacial ice. The research indicates that as glaciers recede, the frequency and intensity of volcanic eruptions in these regions may rise, posing a future threat to surrounding populations and ecosystems.
