Iceland's Volcanoes: How Climate Change Could Speed Up Their Eruptions
Iceland is famous for its unique landscape — a mix of glaciers and active volcanoes. One of the country’s most dangerous volcanoes, Askja, has been in a state of "unrest" for several years. Scientists suggest that climate change and rapid glacier melting might trigger an eruption sooner than expected.
Iceland's glaciers, which cover about 10% of the country's area, play an important role in "holding back" volcanic activity. The weight of the ice presses down on the Earth's crust, helping to keep magma in place. When glaciers melt, the pressure eases, and volcanic activity can increase. Although Askja is no longer covered by ice, melting from the nearby Vatnajökull glacier could still influence its behavior.
What does this mean for tourists and locals?
Iceland attracts many tourists, but scientists warn that climate change could make volcanic activity less predictable. Geophysicist Freyne Sigmund points out that predicting eruptions is difficult, and sometimes there are no warning signs at all.
Volcanoes, especially those exposed due to melting ice, could erupt unexpectedly. This makes it essential for tourists to stay updated on news and alerts, especially if traveling near active volcanoes.
