Now scientists find that many hotspots are dramatically cooler than previously thought, raising questions about their origins. “A substantial fraction of hotspots do not fit the classical plume model,” said Vedran Lekic, a seismologist at the University of Maryland, College Park, who did not p...
How does a volcano form?VolcanoesVolcanoes are an amazing thing to behold: the explosion of thousands of tons of earth and ash into the sky, rolling black clouds blasting energy outward from the volcano's peak. Their fireworks show is impressive, and being able to observe these natural ...
And these things are massive; the average size of each corona is approximately 186 miles wide. That's more than twice the size of Hawaii's Mauna Loa, the largest volcano on Earth.Related Story Mount St. Helens Eruption: Washington, May 1980...
Volcano tourism has become very popular, however, numerous people have been killed while observing volcanoes. If you want to travel to see a volcano, a little research can help you to do it safely. A BBC article covers some of the world's most popular volcanoes that have been recently ...

A volcano's influence on a landscape never occurs in a vacuum. Other land-sculpting factors function in tandem, and the interaction can produce distinctive geomorphic features. High volcanoes often support alpine glaciers, and the carving work of these ice masses counteracts the mountain-building act...
Calderas, large crater-shaped basins, form when eruptions drain a magma chamber and the volcano edifice collapses into the empty space. These often fill up with water, creating round lakes, such as Crater Lake in Oregon. Lava domes form when most of the gas vesicles escape during an initial...
How do volcanic island arcs form? How do extrusive igneous rocks form? What type of volcano is Crater Lake? How do landforms from magma form and become exposed? How is basalt formed? How do underwater volcanoes erupt? What does K-Pg stand for in terms of impact craters?
