Event details

'Volcano Collapse', presented by Professor Hilary Downes FGS

Volcano collapses are rare events on a human time-scale. There have been several small (<1 km3) volcano collapses (e.g. Anak Krakatau and Stromboli) in recent years, producing locally destructive tsunamis. However, we have not yet seen a major volcano collapse, in which 10s-1000s of km3 of material slides into the ocean. There is excellent evidence from onshore and submarine mapping that such collapses happen frequently on geological time-scales (10,000 to 100,000s of years). Such volcano collapses would cause major tsunamis which could carry destruction for 1,000s of km. 

The talk will include work produced by students at UCL and Birkbeck on a variety of examples of volcano collapses from the South Pacific to the Canary Islands and Cape Verdes.

This event is organised by John Wong FGS, Home Counties North Regional Group Chair, and is hosted by Adrian Marsh FGS.

Speaker

Professor Hilary DownesProfessor Hilary Downes FGS

Professor Downes is a Professor of Geochemistry at Birkbeck, University of London, where she teaches courses in igneous petrology and meteorites, and was also Head of Department for nine years. She was President of the Mineralogical Society of Great Britain and Ireland for three years (2016-2019).

Professor Downes' main research interests are in mantle xenoliths, alkaline magmatism and olivine-rich meteorites. She is also a Scientific Associate at the Natural History Museum in London. In this role, she is working on understanding the petrogenesis of highly undersaturated magmatism in the Cape Verde Islands using both cumulate xenoliths and erupted lavas.

Professor Downes has published more than 140 papers, on a wide variety of topics, and was awarded the Collins Medal of the Mineralogical Society in 2022.
