The result is that hotspots form volcanoes at different places on the ... hotspot itself had been active for 165 million years. A diagram shows Easter Island's tectonic context.

A major geological discovery has just linked one of Earth's largest volcanic structures to a submarine hotspot in the Pacific Ocean. This revelation overturns our understanding of how submarine ...

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 ...

Some hotspot volcanoes aren’t so hot after all. Islands such as Iceland and Hawai‘i are thought to form from plumes of superheated rock that rise from a depth of several thousand kilometres.

As the planet's tectonic plates slowly trundle over the hot spot, magma punches through the crust, creating volcanoes. A classic example of this phenomenon is seen in the Hawaii and Emperor ...

While the hotspot itself remains largely stationary, the overriding Pacific plate does not; it creeps northwest at a rate of three to four inches each year. Because of this, the volcanic activity ...

As the planet's tectonic plates slowly trundle over the hot spot, magma punches through the crust, creating volcanoes. A classic example of this phenomenon is seen in the Hawaii and Emperor ...

Al-Tamini Tapu received RTP PhD Scholarship from UQ. Paulo Vasconcelos received ARC Equipment grant to construct the UQ AGES lab. Our new study published in Nature Geoscience on an ancient chain ...

To geologists, volcanoes lined up like Russian nesting dolls in the middle of a tectonic plate usually signal a mantle plume, a hot upwelling coming from the bowels of the Earth. As the planet's ...
