Explore the use of ground-penetrating radar (GPR) in tracing tsunami deposits and erosional scours in this 44-minute talk. Delve into investigations of tsunami sedimentology, which have gained prominence since the 2004 Indian Ocean Tsunami. Learn about the potential of GPR technology to detect sand sheets deposited by tsunamis on coastal plains. Examine case studies from the 2004 Indian Ocean Tsunami in Thailand and Indonesia, as well as the Storegga tsunamis in Scotland and the Shetland Islands. Gain insights into GPR issues, topography considerations, and modeling techniques used in tsunami deposit research. Discover the limitations of GPR and the challenges in distinguishing between storm and tsunami deposits. This comprehensive presentation covers various aspects of tsunami sedimentology research, including study sites, aerial photography, grid surveys, and depth-related tsunami impacts.
