日本中部太平洋海岸，面向日本海沟和相模岛，位于calBP附近。从研究区估计的相对海平面下降可能反映了沉积相的年龄和分析，化石局部构造隆升。砂和砾石层与泥浆交替出现在Onjaku河沿岸。砾石床可能是由风暴潮、洪水和/或海啸侵入而沉积的，砾石床沉积在泥泞的淹没山谷中。砾岩层系。结果表明，calBP周围的相对海面可以解释为海啸水平在calBP周围迅速下降。该沉积是由同一次地震引起的，这一现象与研究区相对海平面抬升不一致。25日,* *
Pacific coast of central Japan facing the Japan Trench and Sagami around calBP. Relative sea-level fall estimated from the study area probably reflected a ages and analyses of sedimentary facies, fossil local tectonic uplift. Sand and gravel beds alternating with mud the outcrops along the Onjaku River. The de-beds might be deposited by storm surges, river floods, and/or tsunamis that intruded into the and gravel beds deposited in a drowned valley muddy drowned valley. The conglomerate bed system. deposited just before the relative sea-level fall The results suggest that the relative sea-around calBP is interpreted as a tsunami level rapidly fell around calBP. This phe-deposit caused by the same earthquake that nomenon is discordant with the relative sea-uplifted the study area. 25,**
