This Week in Volcano News; Lascar Alert Level Raised, 6+ Mile Exclusion Zone

Geology Hub

It appears that the Lascar volcano is primed for a new eruption. As a result, a 10 kilometer or slightly more than 6 mile exclusion zone was declared from the recently active summit vent which erupted on December 10th of 2022. In other news, it was discovered that the Kagamil volcano in Alaska has produced an eruption during the Holocene period. And in Chile, the Puyehue-Cordón Caulle volcano sent particles of ash into the air, but a new volcanic eruption did not occur. 

A special thanks to the Extreme Pursuit YouTube channel for granting me permission to use clips of his footage!
