Active Fault and Paleoearthquake Researches No. 7 (2007)
Tsunami and storm deposits discovered from a coastal lowland succession, western Shizuoka Prefecture
Subduction-zone earthquakes repeatedly occurred along the Nankai Trough with an interval of 90-150 years, as documented in old literatures. Four historical tsunami deposits and one storm deposit were discovered from a coastal lowland succession, Kosai City, Shizuoka Prefecture, by long Geoslicer surveys. For details, see a report by Komatsubara et al. in pages 107-122.
