Volcano Trouble in Alaska; Alert Level Raised at Mt. Spurr, Magma Intrusion Ongoing

In Alaska, the alert level was just raised at the closest volcano to the major city of Anchorage. This occurred at Mt. Spurr, which famously covered the city in a layer of ash due to major eruption in 1953 and 1992. If this volcano were to erupt again, it could produce widespread ashfall which disrupts regional air traffic and causes damage to vehicles. This video will discuss the ongoing volcanic unrest along with what might happen next via the opinion and analysis of a geologist.
