Paleoseismology and paleogeodesy of the Sumatran Subduction Zone

By studying land-level changes over the past 1,000 years, Sieh and his team have gained a better understanding of earthquake behaviour along the Sumatran portion of the Sunda subduction zone; this will lead to improved forecasts for places such as the Mentawai gap, a section of the fault that hasn't triggered a major earthquake in recent years.
