This week, a lava flow entered the ocean on France's populated Reunion Island, forming several acres of new land. Meanwhile, in Alaska, the alert level of the Atka volcano was raised due to multiple signs of unrest. And, in Indonesia, in my opinion data suggests that there is an intrusion of magma occurring underneath the Guntur volcano. Today's video will discuss these stories through the opinion and analysis of a geologist and list the 41 world volcanoes that are actively erupting.

This image was overlaid with text in addition to GeologyHub made graphics (the image border & the GeologyHub logo). This video's thumbnail image is showing a 2018 lava entry from Kilauea (and no lava-ocean entry is currently ongoing there). It is being shown since it looks vaguely similar to the ongoing lava-ocean entry on France's island of Reunion.
