Some parts of the island chain have a 0.6 millimeter-per-year subsidence rate, but others are in a much more dire state.

This melting forms volcanoes. Volcanoes can also form at hotspots, which are places where a really hot plume of rock in the mantle bubbles up, weakening the crust. The volcanoes that form where ...

But that presented the team with yet another conundrum. Volcanoes like those on Easter Island are so-called "hotspot volcanoes." These are common in the Pacific Ocean; Hawai'i is a famous example.

Research unveils a new theory about the origin of the Great Lakes, challenging what we know about their age and formation.

Yellowstone and Hawaiʻi. These systems a well known for producing large volumes of magma through time and leaving chains of volcanic features in their wake, although they do so in very different ways.

The Great Lakes were formed by melting glaciers 20,000 years ago — that’s how most people know the formation of these vast freshwater giants. But researchers at the University of Houston found that ...

Green cones on the ocean floor mark islands associated with "hotspot" volcanoes, such as Hawaii.

Sometimes eruptions are explosive and lava is thrown out as volcanic bombs. Hotspots are places where the magma rises up through the crust. They are caused by a static source of magma, often away ...

and the motions of hotspot volcanoes. In ongoing research, her expertise in the rheology and deformation of the solid Earth has naturally led her to addressing problems related to glacial isostatic ...
