简介：在13:46在2011年3月11日(北京时间)，Mw=9.0的地震发生在日本。由从Guanhekou比较海啸数据，有另外的海啸波浪观察的海洋的车站从东南收集了中国的沿海的区域，仅仅在Guanhekou，最大的波浪高度的位置出现在中间的部分而非在海啸波浪火车的前面，是明显的。海啸繁殖的一个数字模型基于2-D，非线性的浅水方程被造学习影响范围和在江苏发现的特殊海啸波形的主要原因沿海的区域。结果将近显示出那江苏沿海的区域的three-quarters，主要光线的沙山脉向北包括了部分，在波浪火车的中间的部分到达了它的最大的海啸波浪高度。特殊波形的主要原因是专辑在水下地形学黄海和华东海区域调节，它显著地影响了海啸繁殖和波形。尽管陆地边界思考在最大值的位置上带了效果，挥动高度到某个程度，作为在观察点和岸之间的事件波形和距离的限制，它不是特殊波形的主导的影响因素。海啸波浪上的Coriolis力量影响是那么弱的它不是为在江苏沿海的区域的特殊现象的主要原因。学习提醒我们最破坏的波浪可能不在海啸波浪火车出现在第一个。
