This Week in Volcano News; Lava Flow Approaches Highway, Lascar Erupts

Описание: This week, France's Piton de la Fournaise volcano on the island of Reunion erupted, generating 15 separate lava flows. One of these is still active, and has advanced to within 2600 meters of the RN2 highway. Meanwhile, in Chile, the Lascar volcano erupted anew, also producing thermal signatures seen from satellite. And, in Indonesia, a several hour period of repeated multi-kilometer long pyroclastic flows was triggered by heavy local rainfall. 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 image displays a previous eruption of the Piton de la Fournaise volcano on France's Island of Reunion.
