10 Dangerous Volcanoes That You Should Fear
4. Mount Pinatubo, the Philippines
Situated only 55 miles away from the capital Manila, Mount Pinatubo erupted in 1991 after more than 600 years of inactivity. The results were deadly, with over 700 people killed and 100,000 more left homeless. The smoke and ash reached heights of nearly 20 miles. Previous eruptions were relatively tame, which made this disaster all the more surprising.

3. Mount St. Helens, Washington State
When Mount St. Helens erupted in 1980, the resulting destruction led to the death of 57 people, thousands of animals, and wiped out 200 square miles of forest. The eruption reduced the height of the mountain’s summit by nearly 1,300 feet. Four decades later, the forest area remains barren. The United States Geological Survey expects that further eruptions will take place, potentially causing more devastation that could affect the entire Pacific Northwest.
