Presented By: The College of Literature, Science, and the Arts
Professor Rebecca Lange, the Alexander N. Halliday Collegiate Professorship in Earth and Environmental Sciences, Inaugural Lecture
Setting the Stage for a Catastrophic Supervolcano Eruption
PLEASE NOTE: THIS EVENT HAS BEEN MOVED FROM NOVEMBER 15TH TO NOVEMBER 16TH.
The magma type ejected in some of the largest supervolcano eruptions in the U.S. (e.g., Yellowstone, WY and Long Valley, CA) is the most differentiated and evolved on Earth, which gives it unique characteristics. One is that it transitions between 100% liquid and 100% solid within a few tens of degrees of cooling. In this talk, insights extracted from the magma ejected during the Long Valley, CA, supereruption are used to unravel its origin. The evidence points to rapid segregation and ascent of voluminous (>400 km3) melt, which had previously been held in cold storage (i.e., largely crystallized) only months, if not weeks and days, before the eruption. However, the processes that set the stage for such rapid mobilization, leading to a supereruption, took >1-2 Myr to unfold.
