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 ...

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.

It is host to more than 100,000 hotspot volcanoes that have formed in less ... gets stuck in the Play-Doh—as you can see from the diagram below. Incidentally, this lack of argon-40 in Venus ...

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.

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 ...

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 ...

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 ...

The study, published in Nature Communications, is titled "Earth's longest preserved linear volcanic ridge generated by a ...

As demonstrated by explosive news from NASA on Tuesday: Io’s southern hemisphere contains a hotspot of volcanic activity so massive, it is larger than Lake Superior. Detected by the Juno probe's ...

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 ...

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 ...
