The Formation of Long Valley Caldera

Long Valley Caldera was formed millions of years ago by a series of cataclysmic volcanic eruptions that created a massive depression in the earth's crust. The first eruption occurred around 2 million years ago, followed by several others that gradually formed the caldera we see today. The most recent eruption was around 760,000 years ago, and it was one of the largest volcanic eruptions in history. It spewed out more than 600 cubic kilometers of ash and lava, covering an area of over 5,000 square miles. The volcanic activity that formed Long Valley Caldera was caused by the subduction of the Pacific Plate under the North American Plate, which is still ongoing today.
