Australia is an old and stable continent with not many geological risks such as major earthquakes and volcanic eruptions. This activity continued up to a few thousand years ago in Victoria and Queensland. Most volcanoes in the area would have erupted with similar magnitudes. Undara, Queensland, Australia Location: 18.25S, 144.75E Elevation: 3,345 feet (1,020 m) Undara volcano is one of 160 volcanoes in the McBride Volcanic Province. Australia's youngest mainland volcano is Mt Gambier in South Australia which last erupted only about 6000 years ago. There has been no volcanic activity in Australia in the past few hundred years, and no major eruption since Mt Gambier, on the border of South Australia … At least that is what most people think. It expands 1,200 across the place and was formed over 33 million years ago. The world's longest chain of continental volcanoes has been discovered stretching for more than 2,000 kilometres along eastern Australia. It produced eruption plumes of about 10km in height and a large volume of magma erupted over a very short time. Volcanoes in Victoria, New South Wales and Queensland could erupt at any time, he told ABC Science Online ahead of the conference. Just ask the team of scientists that found the world’s largest chain of supervolcanoes hiding down the Eastern flank of our fine continent. In southern Australia and northern Queensland, volcanic activity likely happened within the past 10,000 years.

The lists provided below are mainly volcanoes of Cenozoic aged, with some notable older (Mesozoic and Paleozoic aged) volcanoes included. But Australia’s youngest volcano, Mt Gambier, has also been the most explosive (that we know of) with a VEI of 4. Like we saw in northern and central Queensland, volcanic activity in southern Queensland and NSW is generally divided between central volcanoes and lava fields. The province is about 125 miles (200 km) southwest of the city of Cairns and along the crest of the Great Dividing Range. Most of the central volcanoes appear to start with a large outpouring of basalts that evolve to rhyolites / … Maintaining the volcano and earthquake news sections on this website, the free Volcano Webcams tool and interactive map widget is a free-time, both time- and server cost intensive effort. Throughout the Paleogene and Neogene Periods, volcanoes erupted in eastern Australia and huge lava plains covered large areas. Australia - Researchers have discovered that Australia has the longest chain of volcanoes in one continent. Things are bigger in Australia.
