This week, a major volcanic eruption occurred at the Semeru volcano, leading to casualties and a number of destroyed structures. Meanwhile, a probably albeit unconfirmed intrusion of magma occurred at the Galapagos volcano of Fernandina. And, in Indonesia, the alert level was raised due to a change in activity including ground rumbling at the Sangeang Api volcano. Today's video will discuss these stories through the opinion and analysis of a geologist and list the 42 world volcanoes that are actively erupting. Note: This video's thumbnail displays a prior photo of the erupting Yasur volcano in Vanuatu. A special thanks to afarTV for granting me permission to use two of their video clips!
