Active volcanoes are currently erupting or have erupted in modern history, while inactive volcanoes are dormant and have not erupted for a long time but could potentially become active again in the future. Some examples of active volcanoes include Kilauea in Hawaii and Mount Etna in Italy, while examples of inactive volcanoes include Mount Rainier in the United States and Mount Kilimanjaro in Tanzania.
Pressure inside the earth caused the explosion aftera long build up.

The cryptodome on the side of Mount St. Helens was approximately 1,300 feet long, 65 feet wide, and 40 feet high. It was a large bulge caused by rising magma beneath the volcano before its 1980 eruption.
Yes, the United States has several active volcanoes, including in Hawaii (Kilauea, Mauna Loa), Alaska (Mount Redoubt, Mount St. Augustine), and the Cascade Range (Mount St. Helens, Mount Rainier). Hawaii and Alaska have the most volcanic activity in the U.S.
I don't know who was the first person to climb Mt St. Helens, but below is a good site to visit regarding the mountain: http://www.mshinstitute.org/ It was Thomas J. Dryer
There are many stops from the Oregon Trail that are historical sites. There is also Mount St. Helens which was a volcano that erupted not too long ago.
Although minor steam explosions may have occurred in 1898, 1903, and 1921, Mount St. Helens gave little or no evidence of being a volcanic hazard for more than a century after its eruption in 1857.
