IGPP is pleased to invite you to join its Spring 2023 Seminar Series presentation featuring University of New Mexico's Brandon Schmandt. Dr. Schmandt's talk, "Seismically imaging large continental magma reservoirs" will occur May 16, 2023 in the Munk conference room.
Time: 12:00 pm, Pacific Time
Location: Munk conference room
Abstract: Voluminous continental volcanic systems typically present large magnitude and long recurrence interval hazards based on the geologic record. Seismic imaging provides one of the best ways to examine the contemporary state of magma reservoirs, providing insights into the total volume, concentration, and geometric organization of magma. Most imaging studies indicate small contemporary melt fractions that are likely insufficient to fuel eruptions. However, magma reservoirs are inherently difficult imaging targets, so it often remains unclear whether apparently low melt fractions are the result of limited resolution. The presentation will cover multiple types of seismic imaging with complementary resolution and synthetic tests of hypothetical structures to illustrate constraints on magma reservoirs underlying large felsic calderas in the western U.S.
