Hidden Superchain of Volcanoes Discovered in Australia

Scientists have just found the world's longest chain of volcanoes on a continent, hiding in plain sight. The newly discovered Australian volcano chain isn't a complete surprise, though: Geologists have long known of small, separate chains of volcanic activity on the island continent. That 1,240-mile-long (2,000 kilometers) chain of fire spanned most of eastern Australia, from Hillsborough in the north, where rainforest meets the Great Barrier Reef, to the island of Tasmania in the south.
