Question: Researchers have discovered four extinct underwater volcanoes thousands of feet below the water off the coast of Sydney The calderas are believed to have formed 50 million years ago when supercontinent Gondwana was splitting up into the regions we now know as Australia and New Zealand. And this quartet of 'hotheads' may offer geologists clues about how exactly this tectonic movement took place. The volcanoes were discovered 125 miles (200km) off the southwestern Australian coast using the Investigator ocean explorer from the Commonwealth Scientific and Industrial Research Organisation (CSIRO).
