"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 hosts the longest chain of
continental hotspot volcanoes on Earth. These volcanoes erupted during the last
35 million years (for 1 to 7 million years each), as the Australian continent
moved over an area of heat (a hotspot) inside the planet, also known as a fixed
heat anomaly or mantle plume.
But it appears the Australian hotspot waned with time. And we have found the
volcanoes’ inner structure and eruptions changed as a result. Our new findings
show hotspot strength has key impacts on the evolution of volcanoes’ inner
structure, along with their location and lifespan."
