New evidence shows that very large earthquakes can trigger an increase in activity at nearby volcanoes. An analysis of records in southern Chile has shown that up to four times as many volcanic eruptions occur during the year following very large earthquakes than in other years. This 'volcanic surge' can affect volcanoes up to at least 500 km away from an earthquake's epicentre.
