East Coast mantle hotspot could explain massive Missouri quakes If it exists, Hawaii-style hotspot would have passed under New England. Scott K. Johnson – Sep 18, 2013 11:00 am ...

By analyzing the travel times and paths of seismic waves, scientists can map structures in the mantle, such as mantle plumes and ponding zones — all key to understanding hotspot dynamics.

We still have a lot to figure out about how mantle hotspot plumes work, but we do know that the Hawaii and Louisville plumes go all the way down to the deepest part of the Earth’s mantle.

In geology, a hotspot is a location on the Earth's surface that has experienced active volcanism for a long period of time. Hotspots were thought to be caused by a narrow stream of hot mantle ...

Does Mantle 'Hotspot' Explain Midwest Quakes? Scott Johnson Ars Technica September 19, 2013 AP Photo. Have you ever gone knocking on walls to find a stud so you can hang your new painting of dogs ...

Hot mantle plumes rise from the tops of the basal mantle structures to Earth’s surface, where they appear as hotspots. Arrows represent mantle convection currents. (Adapted from Fig. 2d of ref. 11.) ...

The study examined hotspot lavas, which come from plumes that billow upward from Earth's deep mantle and erupt at volcanoes at the planet's surface. Samoa, Hawaii and Iceland are all hotspots.

A new study has found that 40 million years ago a hotspot softened the mantle rock beneath Greenland in a way that has recently come to fool scientists trying to gauge ice loss in the area. So ...

The Great Lakes formed where they did 20,000 years ago thanks to a hotspot that sat under the supercontinent Pangaea 300 ...
