The subduction zone that carries the Australian and Indian plates beneath Sumatra has been the source of Indonesia's largest earthquakes. We have been studying its paleogeodetic and paleoseismic history, because it affords a unique opportunity to recover precisely dated histories of seismic and interseismic deformation.



Great Sumatran Fault

The Great Sumatran fault carries most of the strike-slip component of oblique convergence across the
Sumatran plate boundary.
