In geology, a hotspot is a location on the Earth's surface that has experienced active volcanism for a long period of time. J. Tuzo Wilson came up with the idea in 1963 that volcanic chains like the...

How do the Hawaiian Islands and other volcanoes that form in the interior of plates fit into the plate-tectonics picture? ... Above: Artist's conception of the movement of the Pacific Plate over the fixed Hawaiian "Hot Spot," illustrating the formation of the Hawaiian Ridge-Emperor Seamount Chain. (Modified from a...

Over the past 70 million years, the combined processes of magma formation, volcano eruption and growth, and continued movement of the Pacific Plate over the stationary Hawaiian "hot-spot" have left a long trail of volcanoes across the Pacific Ocean floor. ... Loihi Seamount, an active submarine volcano, is forming about 35...

Super Volcanoes: Satellites Eye Deadly Hot Spots ; By Robert Roy Britt; ... Analyzing minerals that serve as time capsules of past catastrophes, Bindeman and Valley have found support for other studies suggesting Yellowstone goes nuts every few hundred thousand years. They also propose a reason why: An epic hot spot.

If the hot-spot had become active around 70-100 million years ago, it would have 'scorched' the oceanic crust above it, forming the very oldest sea-mounts now found in the the north ... As the plate moved, however, these volcanoes would have been carried away from the hot-spot and would have become dormant and then extinct.

Kilauea and Loihi share the Hawaiian hot spot with their larger active sibling Mauna Loa. With time, the motion of the Pacific Plate has brought Loihi closer to the center of the hot spot and (possibly) moved Mauna Loa away from it's center. ...

Both Loihi and Kilauea volcanoes sit on the flank Mauna Loa volcano, an older, larger, and still active volcano on the Big Island of Hawaii. ... Loihi shares the Hawaiian hot spot with its larger active siblings Mauna Loa and Kilauea. You can view a schematic representation of the geometry of this situation HERE.

The lava in plate separations is formed by carrying already hot rock up to low pressures near the surface. ... For example, the active volcanoes in Hawaii--Mauna Loa, Kilauea, and the Loihi Seamount volcano off the SE side of the big island of Hawaii--form a small cluster of active volcanoes at one end of a linked chain...
