在2011年东北太平洋地震（M9.0）中，距离地震断层200 km以上的关东地区填海造地广泛发生液化。液化砂土中普遍含有大量的非塑性细粒，有些地方细粒含量超过50%。在20世纪60年代或之后填海的东京湾地区，几乎所有沿着的沙子沉积物都液化了，而与此形成鲜明对比的是，那些比这更老的沙子沉积物却没有液化。
During the 2011 Tohoku Pacific Ocean earthquake (M9.0), liquefaction occurred extensively in reclaimed land in Kanto area more than 200km far from the earthquake fault. The liquefied sand generally contained a lot of non-plastic fines with fines content more than 50% in some places. Almost all sand deposits along the Tokyo bay area reclaimed in 1960s or later liquefied, while in a good contrast, those older than that did not.
