This study presents relative sea-level (RSL) change from 11,200 to 500 cal. BP in the Toyooka Basin, western Japan. Diatom assemblage and sedimentary sulfur analyses were performed for 32 sediment cores obtained from thick Holocene fluvial and mar...

瀬戸内海中部・出崎海岸(岡山県玉野市)の埋没泥炭層について,その堆積環境を再検討し,完新世の相対的海水準変動との関係を考察した.泥炭層は,完新世中期のおもに約7,000~6,600 cal BPの間に,塩性湿地で形成された.この時期は,瀬戸内海沿岸域における完新世の相対的高海水準期に相当し,泥炭層は約7,000 cal BPに海水準上昇が鈍化する一方で,当該地域に及んだ海進に伴って形成されはじめた.泥炭層は高潮位面と最高潮位面との間で形成されたと考えられ,当時の潮位差が現在と同程度であった...
The 1995 Kobe (Hyogoken-Nanbu) Earthquake (Mj 7.2) in Japan, which has been attributed to the Nojima fault of the Rokko-Awaji fault system, resulted in vertical uplifts of 0.19 m at Tarumi and 0.07 m at Akashi, relative to Takasago. Here we evalua...
Mid- to late-Holocene sea-level observations have been obtained from Tamatsu and Tarumi in western Kobe, Japan. In this tectonically active area, we evaluate the local tectonic effect during the Holocene by comparison between observations and pred...
