Devonian

Immense volcanoes exploded across Victoria during the Devonian. Calderas, or craters, many kilometres across were filled with thick layers of hot ash and pumice. Local plants and animals were wiped out, and gigantic clouds of dust and gas probably affected the Earth’s atmosphere. These volcanoes remain in the Victorian landscape as plateaus and mountains since their hard rock resisted erosion.
