Could melting ice cause volcanic eruptions like in Iceland?

Yes, scientists theorize that reduced pressure from melting ice can lead to increased magma formation and more explosive volcanic eruptions.

How many people live near ice-covered volcanoes?

Approximately 160 million people live within 60 miles of a glaciated volcano worldwide.

What is Bardarbunga and why is it concerning?

Bardarbunga is a large Icelandic volcano under a glacier; recent seismic activity suggests it may be awakening, potentially leading to a significant eruption.

Summary

Climate change may be causing glaciers to melt, increasing volcanic eruptions.
Bardarbunga volcano in Iceland shows signs of awakening after a decade of slumber.
Around 160 million people live near ice-covered volcanoes globally.

Scientists are investigating a potential link between climate change-induced ice melt and increased volcanic activity. As glaciers shrink, the reduced pressure on the Earth's crust may allow more magma to form and rise, leading to more frequent or larger eruptions. Iceland's Bardarbunga volcano, situated beneath Europe's largest glacier, is showing seismic signs of magma movement, fueling this concern.

This phenomenon was observed thousands of years ago in Iceland when a massive ice sheet retreated, leading to a significant surge in volcanic activity. Researchers are now examining if a similar pattern will emerge as remaining ice melts due to human-caused global warming. Approximately 245 volcanoes worldwide are covered by ice, and over 160 million people reside near them, highlighting the potential global impact.
