陆地地震将在海底触发相应的地震,不过海底地震将发生在几十年之后,并且其震中离陆地地震震中有几百公里之遥。 华盛顿卡内基学会的保罗·赖德利克和塞尔温·萨克斯研究了多震的日本东北部所发生的全部大地震和自从1600年有可靠的地震纪录以来,发生于相邻的太平洋洋底的地震。 他们发现,陆地地震的地震波缓慢地通过柔软、粘滞的地慢。(构成地壳的板块漂浮于其上)。陆地上大震所产生的地震波传 Terrestrial earthquakes will trigger the corresponding seabed on the seabed, but seabed earthquakes will occur decades later, and their epicenters may be hundreds of kilometers away from the earthquakes epicenter. Paul Ryderick and Selwyn Sachs of the Carnegie Institution of Washington studied all the earthquakes that occurred in the northeastern Japan of the multi-quake and the credible earthquakes that had taken place in 1600 on the adjacent Pacific Ocean floor Earthquake. They found that the seismic waves of the earthquakes slowly slowed down through soft, sticky ground. (The plate that makes up the crust floats on it). Earthquake waves generated by earthquakes on land
