Gakkel Ridge Caldera

Gakkel Ridge Caldera, also known as Gakkel Caldera, is a Pleistocene volcanic caldera located on the Gakkel Ridge beneath the Arctic Ocean, off the northern coast of Siberia. It erupted approximately 1.1 million years ago, with an estimated eruptive volume of 3,000 km3 (720 mi3). This eruption places it at VEI-8 on the Volcanic Explosivity Index, making it one of the most explosive volcanoes on Earth during the Pleistocene along with Yellowstone Caldera and Lake Toba. It is the only known supervolcano located directly on a mid-ocean ridge.
