Guest Videos: Monitoring Volcanoes With Cosmic Rays


You might have heard that they found another chamber in the Great Pyramid recently. Archaeologists and physicists did this by using muons–a type of subatomic particle–to see inside the rock.

Here’s how they did it:



There is another way muon tomography is helping scientists keep people safe: by looking through volcanoes.



This is cutting edge stuff, and work still continues at Soufrière Guadeloupe, where at least five working telescopes were in place in February 2017.

Unfortunately, the last online bulletin of the volcano observatory at Guadeloupe (English translation of website here) is from 2014.

I hope the Great Pyramid discovery may encourage more volcanologists around the world to check out the technique!
