Precursors to Supereruptions at the Valles Caldera, New Mexico
Despite recognition as one the most iconic volcanoes on the planet, there is still much to learn about Valles caldera in north-central NM. A new collaboration between researchers at the Bureau and from UT Austin is seeking to understand the events leading up to supereruptions. In particular, the team is studying the Cerro Toledo Formation, a group of volcanic domes and related ashes that erupted between the large caldera forming events at 1.61 and 1.23 million-years-ago.
