Today we have the great pleasure of interviewing Dr. Andrew Calvert, the Scientist-in-charge of the California Volcano Observatory.  In this conversation we cover a huge range of topics from Mount Shasta, to how magmas form and become more silica rich, the role of federal institutes like CalVo in volcano hazard prediction and monitoring, and some details about potassium-argon (K-Ar, as argon-argon, Ar-Ar) geochronology using noble gases in minerals! 

Dr. Calvert also gives and excellent description of how magnetometers are used to map lava flows on old volcanoes.  This is an incredible tool that helps drive a deeper understanding of the volumes and rates of past volcanic eruptions, which is very valuable information that is used to help forecast volcano behavior!  Dr. Calvert is an excellent science communicator and has a wide variety of experiences studying volcanoes as well as directing observation and hazard prediction efforts. Join us for an amazing conversation with Dr. Andrew Calvert!
