"The geological record shows that new volcanoes in these areas have erupted perhaps every 2,000 years in the past 40,000 years — and given there has not been a major eruption there for the past 5,000 years, a significant eruption seems well overdue," he said.

"There is also similar volcano risk present in various provinces in Far North Queensland, stretching from south-west of Townsville to near Cairns and up to Cooktown in the Far North.

"There are more than 380 volcanoes in total across this part of Queensland," said Joyce, who will receive the Selwyn Medal for significant contributions in the Earth Sciences tomorrow at the Geological Society of Australia's annual Selwyn Symposium. ...
