中文摘要
翻译
在板块俯冲带发生的大地震会引起持续数十年的长期地壳变形,其空间尺度超过100公里。观测到的地壳变形包括过去大事件引起的变形。后者在计算发生下一个事件所需的板块边界上的当前应力积累时成为噪声。为了减少这些噪声,本研究开发了一种利用卫星重力数据准确估计大事件引起的变形的新方法。
英文摘要
A large earthquake in a plate subduction zone causes long-term crustal deformation continuing over decades with a spatial scale exceeding 100km. Observed crustal deformation includes the deformation due to past large events. The latter becomes noises when calculating the present stress accumulation on a plate boundary needed for the occurrence of a next event. To decrease those noises, this study has developed a new method to accurately estimate the deformation due to a large event, using satellite gravity data.
