The latest of the trio of supervolcano eruptions created the park's huge crater, measuring 30 by 45 miles across (48 by 72 kilometers). The volcano's eruption was dramatic, sending plumes of gas and ash thousands of feet into the atmosphere, though early reports of damage were limited. The ongoing earthquake swarm near Takawangha volcano continued over the past week, although seismic data from the local network experienced an outage over the past day which was resolved this morning.

The city is among the communities surrounded by the Tongass National Forest. Check out what's clicking on Foxnews.com. These explosions also launch debris onto the slopes of the cone producing hot pyroclastic avalanches and lahars that sometimes reach the coastline. Our journalists fairly and fearlessly report on the people and interests that determine state policy. The recent volcanic eruption in Tonga was significant- the explosion was heard along coastal Alaska. Eruptive activity is generally characterized by sporadic Strombolian lava fountaining continuing for a several-month period. After talking with Cheryl and crew, I think that the monitoring works.
