Underwater 'Lord of the Rings-like' volcanic landscape discovered off Australian coast
Dozens of ancient lava flows discovered beneath sediment on sea floor

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

Instead, they reveal a hidden volcanic landscape buried deep beneath the sea off southern Australia.
Scientists from the University of Adelaide, the University of Aberdeen and the Commonwealth Scientific and Industrial Research Organisation used 3-D seismic reflection data gathered as part of oil exploration efforts to map the terrain buried deep underneath sediment on the sea floor.
They found a "multitude" of ancient volcanoes reaching up to 625m high that were created by eruptions that happened 35 million years ago.
Dozens of ancient lava flows stretching 34km long and 15km wide were also discovered beneath the sediment.
Researchers hope the images, which are published in the American Geophysical Union Journal, will improve understanding of how volcanoes develop when they erupt underwater.
Dr Nick Schofield, from the University of Aberdeen’s School of Geosciences, who co-authored the study, said: “We have been able to map these ancient lava flows in unprecedented detail, revealing a spectacular volcanic landscape that bring to mind illustrations from Lord of the Rings.
“Submarine lava flows are inherently more difficult to study than their counterparts on the earth’s surface due to their inaccessibility, and the technology we have used is similar in many ways to what is used to produce ultrasound images of babies, but for the Earth.
He added: “By using this technique, we have a unique insight into a landscape that has remained hidden for millions of years, highlighting the growing importance of seismic data in studying submarine volcanism.”
