Understanding the twisted tectonics of the Sichuan basin

The Sichuan basin in southern China is a region of deep geological and seismological complexity, which has so far prevented researchers from understanding its tectonic past. Through fresh analysis of previous observations, combined with the latest modelling techniques, a team led by Dr. Zhe Su at the National Institute of Natural Hazards, Beijing, suggests for the first time that the entire Sichuan basin is slowly rotating. Their result could explain the origins of one of the deadliest earthquakes in living memory, and could also help seismologists to better predict when earthquakes will strike the region in the future.
