Vesuvius is part of a volcanic region that became more active when the Mediterranean Sea dried up about 5 million years ago. A study of the era suggests climate change can influence volcanic activity. @bberwyn photo.
Study suggests link between sea level and eruptions
European researchers say they’ve found more evidence supporting links between climate change and volcanic activity.
Geologists from Switzerland, France and Spain studied compared data on eruptions and climate from about 5 million years ago, finding that volcanic activity in southern Europe doubled during a time when the Mediterranean Sea dried up. They suspect that the changes on the surface contributed to the way magma behaves deep in the Earth.
The era they studied is known as the Messinian salinity crisis, when the Strait of Gibraltar was blocked and the Mediterranean temporarily isolated from the Atlantic, according to the study published in Nature Geoscience.
