Vanishing Volcanoes: Now you see them, now you don’t (CANCELLED)
Save event

We regret to announce that this talk has been cancelled to prevent the coronavirus spread following communication from the Geological Society of London. This talk will be rescheduled for a future date - apologies for any inconvenience caused. Page updated: 12 March.

Volcanoes are often portrayed as towering mountains rising into the sky, but in reality they are built in a geologically short period of time of many weak parts. 

As a result, the collapse of a volcano is in many cases inevitable. There are now well over 500 recognised cases of volcanic collapse and in the in the past 400 years these events and the associated explosive eruptions have been attributed to more than 20,000 fatalities. 

Just how big are these collapses, and what could it mean if one were to happen in the near future?

This public talk, organised by the South West Group of the Geological Society, will be given by Dr Mark Thomas from the University of Leeds. Doors open at 18:00 for networking. 

Email Dr Irene Manzella ( for more information.

The talk is sponsored by the Engineering group of the Geological Society of London.
