Australia has many ancient volcanoes. But how were they formed?

If you take a trip this summer, you may pass several ancient sentinels of Australia’s volcanic past. Many of them, like the Glass House Mountains, are hard to miss. These ancient volcanic plugs are all that remains of eruptions that occurred around 25 million years ago. They are among hundreds of ancient volcanic remnants that […]

Australia was once home to hundreds of ancient volcanoes. We can finally find out why

[ad_1] Geologically, Australia is a relatively quiet place to live. Earthquakes are rare and typically sweet, and as with volcanoes, there has not been as much as a burp of magma on the continent in thousands of years. It hasn’t always been that way. In fact, the earth is littered with the remains of mysterious […]

Why has the East Coast had hundreds of volcanoes since the age of the dinosaurs?

Australia’s east coast is littered with the remains of hundreds of volcanoes – the most recent of which is only a few thousand years old – and scientists are struggling to explain why so many eruptions have taken place over the past 80 years. last million years. Now geoscientists from the University of Sydney have […]
