Wah Wah Springs Caldera

Common card · No. 370786

Wah Wah Springs Caldera is an extinct volcanic caldera located in the US state of Utah. Discovered in 2013, the Wah Wah Springs caldera produced one of the largest explosive eruptions by volume in Earth's history. The estimated eruptive volume was ~5,500 to 5,900 cubic kilometres (1,300 to 1,400 mi3) of dacite. Also known as the Wah Wah Springs formation, it erupted ~30.06 million years ago in the early Oligocene. It is the largest known eruption of the Indian Peak–Caliente Caldera Complex, and includes flows over 500 m (1,640 feet) thick. It was the second most energetic event to have occurred on Earth since the asteroid impact at the end of the Cretaceous period.
