UC Berkeley researchers discovered previously unknown zones of slow seismic waves, which may help determine the process of the formation of hotspot volcanoes. Taking seismic wave data from multiple ...

Volcanic relics scattered throughout the Australian landscape are a map of the northward movement of the continent over a 'hotspot' inside the Earth, during the last 35 million years. Volcanic relics ...

Our new study published in Nature Geoscience on an ancient chain of Australian volcanoes is helping to change our understanding of "hotspot" volcanism. You may be surprised to learn eastern Australia ...

A fiery mystery has puzzled geologists for decades: where did the lava fueling one of Earth’s largest volcanic events come from? A new study may finally have the answer. Scientists have long believed ...

The Earth's mantle might not always move along in lockstep with the overlying tectonic crust—as set out in science textbooks for decades—but may instead behave differently. This is the conclusion of ...

Scientists long wondered whether there were places on Earth where extremely hot material from the core of the Earth moves up through the mantle, and if these plumes were responsible for some volcanic ...

Geologists led by the University of Maryland and the University of Hawaiʻi finally connected the dots between one of the largest volcanic eruptions in Earth's history and its source deep beneath the ...
