About the Event: 

Recently, I have moved away from land-based investigations of Sumatran tectonics and have begun to focus more on geological interpretation of marine seismic data collected during the 2014 MegaTera expedition, as well as regional reflection seismic data examined in collaboration with the marine geophysics group at IPG Paris.  These data provide a new wealth of geological information about the Sumatran subduction system.  This talk will be an open discussion centred on observations that I believe are important for understanding the active tectonics of the Sumatran margin, as well some big picture questions that arise from these observations.  General topics will include: tsunamigenesis within the Sumatran accretionary wedge, both past and future; bringing geophysical models and geological data closer together; the large-scale structure of the accretionary prism in Sumatra; and how we identify and understand submerged active faults in forearc settings.  Because many of these ideas fall outside of my past expertise, and are directly related to ongoing work in various research groups at EOS, I invite critical input and discussion from the audience. 

About the Speaker: 

Kyle Bradley

Dr. Kyle Bradley is a Research Fellow at the Earth Observatory of Singapore, where he works on understanding the active tectonics of Southeast Asia. He received a Ph.D. from the Massachusetts Institute of Technology, where he studied extensional tectonics of the Aegean region (including a lot of paleomagnetic work), and a B.S. in Geology from Caltech. He has taught undergraduate and graduate geological field mapping courses, and also teaches GIS and photogrammetry.
