What Is Left After Tsunami Disasters? – A Sedimentological Perspective

Explore the sedimentological perspective of tsunami disasters in this comprehensive lecture. Delve into the devastating impacts of major tsunamis, including the 2004 Indian Ocean and 2011 Japan events. Learn about the importance of studying tsunami deposits to assess coastal risk and the challenges in identifying paleotsunami evidence. Examine various types of tsunami deposits, their similarities to storm deposits, and post-depositional alterations. Discover new methodologies enhancing traditional sedimentological and stratigraphic approaches, including paleogenetics. Analyze case studies from Thailand, Japan, and Greenland, exploring deposit characteristics, thickness distribution, and rapid plant development. Investigate marine and offshore tsunami deposits, sediment sources, and post-depositional processes. Gain insights into distinguishing tsunami deposits from storm deposits and understand the criteria used for identification. Engage with the latest research on sedimentary DNA, boulder deposits, and the impact of rolling icebergs on coastal landscapes.
