The Ora Caldera is a Permian supervolcano in the Southern Alps of northern Italy. This 42-kilometre-wide (26 mi) and 40-kilometre-long (25 mi) caldera was formed by a supereruption 277–274 million years ago that produced more than 1,000 km3 (240 cu mi) of rhyodacitic-rhyolitic ignimbrite. The ignimbrite from this eruption forms the 10-to-1,350-metre-thick Ora Formation, which represents the youngest eruptive unit of the Athesian Volcanic Group.
