This research project was initiated as a result of the 11th November 2012 Mw6.8 Thabeikkyin earthquake on the Sagaing Fault in Myanmar. Until now no detailed field studies have been conducted on the surface deformation caused by a modern earthquake in SE Asia. The Thabeikkyin earthquake surface rupture is beautifully developed and was well preserved during the November May 2012/13 dry season in Myanmar. It provides an excellent opportunity to understand how the Sagaing Fault behaves. This project aims to systematically map and understand the coseismic (formed during an earthquake) surface rupture. This work will support stress change modelling along the Sagaing Fault. Stress change modelling highlights where the fault is relaxed by an earthquake, and where stress is elevated. Earthquakes nucleate in areas of elevated stress, so modelling can be used to assess the seismic hazard posed by the fault. Funding comes from Natural Environment Research Council (NERC) Urgency Grant NE/K016474/1 'Coseismic deformation associated with the 11th November 2012 Shwebo earthquake, Myanmar'. NERC is the UK's non departmental public body responsible for funding and managing research into environmental sciences. Principal Investigator is Dr. Ian Watkinson, Department of Earth Sciences, Royal Holloway University of London. Project Partners are Soe Thura Tun, Myanmar Geosciences Society and Myanmar Earthquake Committee and Prof. Kuvvet Atakan, University of Bergen, Norway. Working alongside us are Lin Thu Aung, Dr. Thura Aung, and Dr. Myo Thant of the Myanmar Earthquake Committee.

Acknowledgements We (Ian Watkinson, Soe Thura Tun and Kuvvet Atakan) are grateful for the support of the Myanmar Earthquake Committee, the Ministry for transport in Myanmar and NERC in the UK. We would especially like to thank Lin Thu Aung, Thura Aung and Myo Thant for their valuable and ongoing contributions to the research. Fieldwork along the Sagaing Fault was made possible and enjoyable by the kindness and hospitality of a great many local people. We are immensely grateful to them all. Learn about their experiences of the earthquake here.
