Mount St. Helens, Mount Rainier and Mount Hood are all major volcanoes that lie along the infamous "Ring of Fire" that runs down the west coast of the United States, and all of the seismic activity that has been taking place in the region has many concerned about what may happen next.  Earlier this month, I wrote about how 45 earthquakes of magnitude 2.5 or greater hit Alaska in just one 24 hour period.  This week, it is volcanic activity that is raising concerns.  The earthquake swarms at Mount St. Helens are making headlines all over the globe, and on Tuesday two major volcanoes in Alaska suddenly erupted on the exact same day…

An eruption at Bogoslof volcano – one of two to erupt in the Aleutian Islands Tuesday – is its first after more than two months of inactivity, causing ash to fall in a nearby community before drifting south over the Pacific Ocean.

The Alaska Volcano Observatory said Tuesday night's eruption at the volcano about 60 miles west of Unalaska, which began just after 10:30 p.m. and lasted for 73 minutes, sent a plume to an altitude of 34,000 feet.
