Geologists from the Yellowstone Volcano Observatory are often asked to estimate how likely future eruptions are at Yellowstone, but it’s no walk in the national park.| USGS
Mount St. Helens is an active volcano located in southern Washington state. Its most famous eruption on May 18, 1980, killed 57 people, destroyed 250 homes, and caused billions of dollars worth of damage. It was the most destructive volcanic event in American history. Fortunately, however, there was a great deal of activity in the months before the eruption. Nearby communities, as well as the rest of the nation, had plenty of warning that a major eruption was coming.| Sciencing
Volcanoes are powerful and might even seem terrifying, though for good reason.. The destruction some of them have caused in the last century can't be ignored.| Sciencing
If you think that any volcanic eruption is just like another, think again. As different types of volcanoes exist, so do different types of eruptions and their levels of impact. Volcanologists categorize volcanic eruptions into two types: explosive and effusive. However, classification of the types of volcanic explosions is not consistent throughout the field.| Sciencing
The vast majority of volcanic activity occurs where tectonic plates collide, called convergent boundaries, or spread, called divergent boundaries. However, there is a special class of volcanoes that form within plates. These inter-plate volcanoes are known as hotspot volcanoes. Hotspot volcanoes that form under continental plates are called super volcanoes, representing the most powerful and violent volcanoes on Earth.| Sciencing
Volcanoes are one of nature's most destructive forces. However, volcanoes are also one of nature's chief constructive forces. Volcanic eruptions are responsible for creating new crust and geological landforms. The specific results of a volcanic eruption differ widely; each volcano type has a distinct eruptive nature.| Sciencing
