Scientists trace how a single underground heat source formed dual volcanic chains near Australia

UPDATE - follow-up to How one plume of hot rock built two volcano chains off Australia's coast - Phys.org: Researchers have mapped out the geological process explaining how one deep underground plume of hot rock successfully formed two separate chains of volcanoes off the coast of Australia. This new finding sheds light on deep earth activity and the way magma moves beneath the ocean floor to shape major geological features over long periods of time.
