"Massive Earthquakes and Tsunamis: Contributing Factors Revealed by IODP EXP 362" presented by Dr. Peter J. Vrolijk.  The International Ocean Discovery Program (IODP) Expedition 362 sailed in summer of 2016 to evaluate whether the thick sedimentary section subducted at the Sumatra margin consists of materials that through burial and diagenetic processes could contribute to one of the largest earthquakes recorded and rupture the seafloor and trigger a devastating tsunami.  The results of the research offer one more constraint on the myriad expressions of subduction zone seismicity. Dr. Vrolijk, a MIT graduate and retired from ExxonMobil, now works as an Adjunct Professor with New Mexico Tech, Science, Engineering University.
