Free public lecture on Stromboli Volcano - 17th October 6pm

Thursday 17 October at 6 pm
Reception Room, Wills Memorial Building, Queen's Road, BS8 1RJ

Free entry, booking not required

Stromboli volcano (Italy) belongs to a class of volcanoes that explode frequently against a background of substantial continuous gas emissions. The explosions are spectacular and the continuous gas emissions have a significant effect on the Earth’s atmosphere. This lecture will consider the processes involved that allow these two modes of behaviour (explosions and gas emissions) to co-exist. In particular, I will show how we can combine results from laboratory flow experiments and computer models with field observations and petrological and textural data from rock samples to advance our understanding of this style of eruptive behaviour.
