Understanding Tsunami Sources from Surveyed Tsunami Heights and Sediment Deposits
Tsunami deposits contain a record of past tsunamis. As tsunami deposits are formed by tsunami flows carrying both offshore and near-shore sediments, the characteristics of tsunami deposits are indicative of the characteristics of tsunami flows.
Two research tasks are conducted here by EOS: understanding tsunami source and near-shore tsunami flows from sediment deposits in coastal caves, and understanding tsunami sources using the spatial distribution of tsunami wave energy derived from post-tsunami surveys. Numerical models are first verified by carefully designed laboratory tests and then employed to full-scale problems, including the newly discovered tsunami deposits inside a coastal cave in Aceh province.
