Pavlof Volcano Update; Alert Level Raised at United States Volcano

Описание: The alert level of a United States volcano was just raised, specifically at a stratovolcano known as Pavlof. Located in Alaska, this is the second most active volcano since 1800 in the entirety of the United States, and it currently appears to be undergoing an episode of unrest. Whether or not this leads to an eruption or subsides is uncertain, which today's video discusses.
