“This reinforces what some researchers have argued previously, which is that the term ‘hotspot’ is misleading and that volcanoes that don’t fit the plate tectonic paradigm should rather be referred to as ‘melting anomalies,'” said seismologist Ross Maguire from the University of New Mexic...
The researchers suspect these strange features form similarly to some of the volcanoes found here on Earth. Molten magma likely creeps up from planet's warm mantle, kind of like hotspot volcanoes that pop up in places like Hawaii and Yellowstone. And these things are massive; the average size...
The volcanoes in Iceland are unique because they form from two different types of tectonic settings: a hotspot and divergent plate boundary. It's All About Gas JOHAN ORDONEZ//Getty Images But why do they blow their tops when they do?
As we examine supervolcanoes in this article, we'll pay particular attention to the fitfully slumbering giant in the U.S.'s backyard: the hotspot beneath Yellowstone National Park, home to 2-3 supereruptions in the past 2.1 million years [sources: Achenbach; Robinson; Tyson; USGS]. And ...

How often does the Yellowstone hotspot create a new caldera? Can a volcano erupt more than once? How many volcanoes erupt every year? How does a fissure volcano erupt? When will Mayon volcano erupt again? How long has Kilauea volcano been active? How long do volcanoes stay active? When did...
Yellowstone sits above a spot in the Earth's mantle where columns of hot, molten rock called plumes rise to form volcanoes in the planet's crust. This spot is called a hotspot, and it creates atype of volcano not associated with a plate boundary. Yellowstone has produced three calderatypes...
How often does the Yellowstone hotspot create a new caldera? How fast does ocean warming happen? Where do tsunamis occur? How do deep ocean currents regulate climate? What is red tide caused by? How does an upwelling form from the Antarctic circumpolar current?
