When volcanos erupt, these geologic monsters produce tremendous clouds of ash and dust--plumes that can blacken the sky, shut down air traffic and reach heights of roughly 25 miles above Earth's surface. A new study led by the…

For the first time, long-term photogrammetic series document the "life cycle" of a volcano. The analyses shows that volcanoes have a kind of memoryCredit: GFZ Volcanoes are born and die - and then grow again on their own…
