Abstract

Hi Reddit!

I’m Dave Petley, Pro-Vice-Chancellor for Research and Professor of Geology at the University of East Anglia in the UK. I also run the Landslide Blog, which sits on the website of the America Geophysical Union, the World’s largest earth science organisation. For 25 years I have been doing research into landslides, which collectively kill about 14,000 people per year worldwide on average. I’m interested in particular on how landslides occur – in other words what happens inside a slope to make it start to slide or flow – and on the impacts that landslides have on society. I’ve worked all over the world, including in Europe, the US, Chile, Taiwan, China, Nepal, Pakistan and New Zealand. In the early part of my career I worked mostly on landslides triggered by extreme rainfall, especially during typhoons in Asia. More recently my main focus has been on landslides triggered by large earthquakes, such as the Sichuan earthquake in China in 2008, in which over 20,000 people were killed by landslides. I’ve also worked on a number of landslide crises, such as the 2010 Attabad landslide dam in Pakistan. Sadly, at the moment the impact of landslides is increasing worldwide due to the combined effects of climate change, deforestation and poor slope management.

I hope to answer lots of interesting questions about landslides, including where they happen, why they occur, how they are responding to climate change and how they are affecting people during the AGU AMA! See you all soon!

I’ll be back at noon EST (9 am PST, 5 pm UTC) to answer your questions, ask me anything!

The AMA is still in progress

Science AMA Series: Hi Reddit, I'm David Petley, author of The Landslide Blog and Pro-Vice-Chancellor (Research and Enterprise) at the University of East Anglia in the United Kingdom. I'm here to talk about the science and management of landslides. AMA! is still ongoing! After the AMA is finished it will be permanently archived, assigned a digital object identifier (DOI), and formatted as a white paper.

To learn more about The Winnower and publish your own ideas and research, sign up here! We bring traditional scholarly publishing tools (DOI & permanent archival) to blogs, essays, grants, protocols, how-to's, essays, and other media, including reddit AMAs, because scholarly communication doesn’t just happen in scholarly journals.
