What causes some eruptions to be more explosive than others?

Is it the total driving gas fuel, or how fast the gas escapes?

This talk, by Professor Terry Plank from Lamont-Doherty Earth Observatory, Columbia University, examines both the volatile content and the speed of magma ascent immediately prior to eruption. Chemical zonation preserved inside glass pockets and crystals provide some of the fastest clocks in geology. These timescales of chemical diffusion operate over minutes to hours in the run-up to eruption.

Professor Terry Plank is the Geological Society of America James B. Thompson Distinguished International Lecturer. Professor Plank is a world expert on magmatic systems and processes and her significant and lasting contributions to the field of Earth Sciences have been well recognised.

Professor Plank is a Fellow of the American Geophysical Union, The Geochemical Society, the Geological Society of America, and the Mineralogical Society of America and since 2013 a member of the National Academy of Sciences.

Don't miss Professor Plank's second talk on Friday 28 July called "How Hot? How Deep? Solving for the Geotherm in Melting Regions Under Continents”.

Book individual or group discussion time with Professor Plank.

Please contact Manuela Tost to schedule time with Professor Plank on Friday 28 July.
