Earthquake Ruptures in China: Testing Earthquake Recurrence Models

Earthquake recurrence models are important to assess seismic hazard but remain poorly constrained due to insufficient of data. In order to assess which model is most useful, we study the exceptionally well-preserved archive of earthquake ruptures along the eastern Altyn Tagh fault (China). We use an unmanned aerial vehicle to acquire high resolution topographic data and to reconstruct seismic offsets. We use extant dating techniques to constrain the timing of the events. The resulting data, combined with sub-surface trenching, provide long term slip rates and earthquake return times, and also help to refine seismic hazard assessmen
