| Outline of Final Research Achievements |
We continue paleo-seismic studies through Late Holocene-time in coastal marsh ponds along the Nankai Trough. These ponds which situate co-seismic subsidence areas have continuous muddy sediment stratigraphy and sporadic tsunami sediment composed of coarse material. Total 13 cores collected from a coastal pond Zasa-ike which locate behind beach-ridge along southeastern coast of Kii Peninsula. The remarkable event found in sediment, which are 2000-2300yBP (=2K event). 2K event consists thick sand, well rounded gravel in chaotic mud with wood fragment derived from forests surrounding the lakes. The 2K events have also found widely, not only Kii Peninsula but southern Shikoku through the Nankai Trough.
