Improvements in the paleotsunami record along the Aceh coast of Sumatra

Paleotsunami studies have shown that the 2004 Indian Ocean tsunami could have been anticipated. Nonetheless, important gaps in our understanding of past tsunami sources, characteristics and timing remain. At our Aceh Coastal Cave site, we propose to resolve important gaps in the record and relate sedimentology to hydrodynamics.  In swales behind settlements from the northern Aceh coast, which were devastated in 1394 CE, we will test the twin 1394-1450 CE tsunami hypothesis. We will also revisit some of our other earlier coastal-plain sites along the western Aceh coast and, in the final year of the project, reconnoiter for new sites.
