Lava ‘Music’ Might Explain The Eruption Rhythms of The World’s Most Active Volcano

Lava ‘Music’ Might Explain The Eruption Rhythms of The World’s Most Active Volcano

The sounds of sloshing lava are music to a volcanologist’s ears. The reverberating belches and burps can help reveal what’s going on deep within a volcano’s belly. Putting an ear to the Kīlauea volcano in Hawaii has allowed researchers to track the temperature of magma and the migration of volcanic gasses as they bubble to … Read more

A long-dormant underwater volcano near Antarctica has woken up, triggering a swarm of 85,000 earthquakes. The swarm, which began in August 2020 and subsidized by November of that year, is the strongest earthquake activity ever recorded in the region.
