Please note, due to technical issues on the night, this video is of Professor Petley's slides, with his voice accompanying them, rather than a direct video of him speaking at the lecturn. There are slight gaps in the sound in a couple of places, and where Professor Petley refers to points within slides where he would have used the laser pointer, this will not be visible.

Professor Dave Petley, delivered a public lecture to an audience of over 300 on Wednesday 6 March 2019. His lecture, 'Things are going downhill fast: understanding massive landslides' focussed on his research area and marked the start of the forthcoming British Science week.
Professor Petley began by defining landslides, explaining that landslides occur on a huge range of scales. He then went on to discuss the key concepts that are required in understanding landslides, these include: water, the structural change of materials, rocks with defects, earthquakes in mountains and a lack of understanding in why landslides travel so far and fast. Landslides are 'often part of a highly complex chain of events'.
Professor Petley’s research concentrates on the impact of landslides in particular. A selection of case studies were discussed, including the 2008 Wenchuan (China) landslide and the 2010 Attabad (North Pakistan) landslide. The case studies highlighted the social impact and devastation of such natural disasters. When talking about Attabad, Professor Petley elucidated his involvement in the 2010 crisis. He was an integral part of the relief effort alongside the charity Focus as well as a source of information in understanding why this natural disaster occurred.
Following the lecture, questions were taken from the audience.
The lecture was incredibly interesting and provided the audience with a real insight in to the complexities and varying scales of landslides and the devastation they cause.
