Room G8, School of Earth Sciences, Wills Memorial Building

We are pleased to welcome Dr. Corrado Cimarelli from Ludwig-Maximilians-Universität who will be delivering this week's Hotstuff seminar:-

Title: The bright side of the plume. Volcanic plume electrification: observations and experiments 

Abstract:

Ash-rich volcanic plumes are often associated with intense electrical activity and the generation of volcanic lightning. Monitoring electrical discharges associated with explosive eruptions can provide crucial information on the dynamics and structure of the plume as well as on the mass eruption rate and cargo of erupted fine ash. Nevertheless, our understanding of volcanic lightning is still limited due to lacking of i) systematic instrumental observations and ii) the limited number of experimental investigations on the electrical properties of volcanic materials and the opportunity of replicating volcanic plume conditions in the lab. We recently contributed to the understanding of both these aspects by performing multi-parametric observation of volcanic lightning at Sakurajima volcano in Japan and by achieving volcanic lightning in particle-laden jets generated in the lab.

All staff and students welcome.
