This week, the Mount Etna volcano in Italy produced an unusually long pyroclastic flow associated with a 1 million cubic meter landslide of its southeast crater cone. Meanwhile, in Guatemala, a strong paroxysm occurred at the Fuego volcano, generating a 7.7 kilometer long pyroclastic flow. And, in Indonesia, the Raung volcano erupted anew, producing a sustained ash plume. This video will discuss these stories and list the 48 volcanoes which are actively erupting around the planet. Note: There is a chance that I overestimated the pyroclastic flow length in today's video as some sources claimed it only reached 7 kilometers in length at Fuego.
