The STEM Lecture: Volcanoes by resident Stephen Senturia will be given at 10:30 am in the Performance Hall and streaming. Stephen Senturia has a PhD in Physics from MIT, where he taught for 36 years in the Department of Electrical Engineering. He has had a long-standing hobby-level interest in the geology that surrounds us. Today’s lecture, the second of a series of three, is on Volcanoes – how heat from the core manages to get to the surface and melt solid rock to make magma that can then break out in an eruption. We will survey the different types of volcanoes and understand how and why they can be different. Part 3, on Earthquakes and Tsunamis, will be presented in March.
