伊达低地是毗邻日本中部骏河湾东岸的一个小盆地，下面有一个与海洋入侵有关的奇异沙层。这种分选不良的粗砂沉积物含有微咸海硅藻，与富含有机物的泥浆互层，可能沉积在偶尔受到海洋影响（例如风暴或海啸）的淡水沼泽或沼泽环境中。根据历史文献，骏河湾每100年至少发生一次大风暴；然而，当地的地质记录显示，大约在大约 100 公里之间仅沉积了两块大面积的沙层。公元前 500 年和约。公元1460年。历史和地质记录中海洋入侵事件频率的差异表明，罕见的海啸或特大风暴最有可能在低地沉积如此粗的沉积物。沙子的沉积年龄受到从沙子下方和上方取样的植物大化石和烧焦物质的放射性碳年龄的限制：下方为公元 1140-1340 年，上方为公元 1090-1390 年。这些年龄与 1096 年、1099 年、1293 年或 1361 年已知海啸或与海啸或风暴相关的另一次未记录的过度冲刷造成的沙子沉积一致。
There is an exotic sandy layer associated with a marine incursion beneath the Ita lowland, a small basin adjacent to the eastern shore of Suruga Bay, central Japan. This poorly sorted, coarse sandy deposit, which contains brackish–marine diatoms, is interbedded with organic-rich mud and was likely deposited in a freshwater swamp or marsh environment subject to occasional marine influence (e.g., storm or tsunami). According to historical documents, there has been at least one large storm in Suruga Bay every 100 years; however, the local geology records deposition of only two extensive sand sheets between ca. 500 BC and ca. AD 1460. This difference in the historical and geological records of the frequency of marine incursion events suggests that infrequent tsunamis or extraordinarily large storms are the events most likely to have deposited such coarse sediments on the lowland. The depositional age of the sand is constrained by radiocarbon ages of plant macrofossils and charred material sampled from below and above the sand: AD 1140–1340 below and AD 1090–1390 above. These ages are consistent with deposition of the sand by known tsunamis in 1096, 1099, 1293, or 1361, or another undocumented overwash associated with tsunami or storm.
