Last week I heard the GoodSchist podcast featuring Chris of good schist, Chris of Highly Allochthonous and Julia of The Ethical Paleontologist. That talk featured volcanism among other topics.
Now, OnPoint Radio has a one hour talk on volcanism. Invited guest are Peter Cervelli and Cyrus Read from the Alaska Volcano Observatory, Marianne Guffanti of the U.S Geological Survey and Mark Simons of Seismological Laboratory at Cal Tech. They talk with Tom Ashbrook and callers from all over the U.S. about the recent volcanic activity in Alaska, Chile and Tonga.
