Neotectonics of the Sumatran Fault

We wish to understand the roles that active faults play in accommodating Sumatra’s oblique plate convergence and the potential hazards to society associated with them. To this end, we are measuring long-term Sumatran Fault slip rates by dating laterally offset features. Thus far, we have revised the slip rates using lateral offsets of channels incised into caldera tuffs, leading to a new model for how the great faults of Sumatra work. We now seek to extend this record backwards in time, by studying lateral offsets of entire volcanic systems that represent ~1 million years of slip on the Sumatran Fault.
