Is Mt Gambier an active volcano?
While Mount Gambier and Mount Schank are considered volcanically active, but are unlikely to erupt again.
How many volcanoes are in Mount Gambier?
It contains four lake-filled maars called Blue Lake, Valley Lake, Leg of Mutton Lake, and Brownes Lake. Both Brownes and Leg of Mutton lakes are dry in recent years, due to the lowering of the water table….Mount Gambier (volcano)

What would happen if Mount Gambier erupted?
Dr van Otterloo said a similar eruption in the region would cause closure of the major airspace of eastern Australia, health risks from fine ash composed of glass fragments, destruction of crops and impacts on livestock up to 100 kilometres from the erupting site and disruption to local infrastructure.
Will Mt Gambier erupt?
Mount Gambier’s Blue Lake and the nearby Mount Schank are Australia’s most recently active volcanoes, having erupted about 5,000 years ago. With an estimated eruption frequency of once every 10,000 years, the likelihood there will be activity anytime soon is not high.
When did the last volcano erupt in Australia?
about 5,000 years ago
The most recent eruptions on the Australian mainland occurred at Mt Gambier and Mt Schank in South Australia about 5,000 years ago. These volcanoes are part of a larger volcanic area or province in south-eastern Australia, where we can still expect another eruption.
Has Australia ever had a volcanic eruption?
The most recent eruptions on the Australian mainland occurred at Mt Gambier and Mt Schank in South Australia about 5,000 years ago. These volcanoes are part of a larger volcanic area or province in south-eastern Australia, where we can still expect another eruption.
Is Toowoomba an extinct volcano?
THE likelihood of Toowoomba exploding in a volcanic eruption is virtually negligible, even though geologists are certain that Toowoomba is sitting on an extinct lava pool. “Basalt spreads downwards from the centre volcanic plug, making it clear that this mountain is an extinct volcano,” he said.
Why there is no volcano in Australia?
Volcanoes in Australia Active volcanoes generally occur close to the major tectonic plate boundaries. They are rare in Australia because there are no plate boundaries on this continent. As the continent moved northward, the stationary hot spot formed volcanoes further to the south on the continent.
Is Melbourne sitting on a volcano?
Victoria and South Australia do host an active volcanic field, called the Newer Volcanics Province (NVP). Between Melbourne and Mt Gambier there are more than 400 small volcanoes that erupted over a period of 6 million years.
Is the Mt Gambier volcanic complex a single volcano?
The Mt. Gambier Volcanic Complex (MGVC) is not a single volcano, but a type of volcano complex known as a “monogenetic volcanic centre”, because each volcano will only erupt once ( Van Otterloo et al., 2014 ). Part of the Newer Volcanics Providence of south-eastern Australia, the MGVC contains the youngest volcanoes in Australia.
When was the last time Mount Gambier erupted?
The earliest volcanoes in the Newer Volcanics Province erupted around 4.5 million years ago, or perhaps up to 7.8 million years ago. Most recently, Mount Gambier last erupted about 5450 years ago, while nearby Mount Schank erupted shortly afterwards.
How big are the maar volcanoes in Victoria?
Victoria hosts two of the world’s largest maar volcanoes: Tower Hill near Warrnambool and Lake Purrumbete near Camperdown. These large maars are more than 3km wide, whereas normally maars are only up to 500m in diameter. The size of these maars is actually the result of eruption from multiple vents that merged into a larger maar crater.
