Mount Spurr:
Mini-earthquakes occured in Alaska’s Mount Spurr recently, sparking fears among scientists that the towering 11,000-foot volcano may be on the verge of a major eruption.
- It is an ice- and snow-covered active stratovolcano complex located in the north-central Cook Inlet region about 100 kilometers west of Anchorage, Alaska, United States.
- The volcano sits at the south edge of a break in the Alaska Range.
- It is composed mostly of andesite.
- It consists of a breached stratovolcano, a lava dome at the summit of Mount Spurr, and Crater Peak vent, a small stratocone on the south flank of Mount Spurr volcano.
- The mountain is 3,000 meter high and is topped with a 5 by 6 km caldera.
- The mountain suffered a crater collapse around 10,000 years ago that created Chakachamna Lake.
- There is an active icefield in the caldera and multiple glaciers.
- The volcano last erupted in 1992, that resulted in heavy ashfall and affected air travel in the region.
