Intellectual Merit The work proposed is to relocate and examine the focal mechanisms of mid to large size earthquakes along the circum-Pacific subduction zones. Assuming that along-strike variations in rupture processes within the subduction zone reflects fault zone conditions, the PIs will address the following: 1) whether slow earthquakes occur in known tsunami generating areas; 2) whether areas with slow earthquakes have certain characterizes which might make them prone for generating tsunamis; and 3) whether there are spatial correlations between slow slip events and deep episodic tremor and aseismic slip. Broader Impacts The project will support two early career female PIs and will contribute to the understanding of two MARGIN?s focus sites. This proposal also relates to Societal Theme 2 of the ORRP: Increasing Resilience to Natural Hazards

提出的工作是重新定位和研究环太平洋俯冲带中大型地震的震源机制。假设俯冲带内破裂过程的沿走向变化反映了断裂带的条件，那么pi将解决以下问题：1)在已知的海啸产生区是否发生慢震；2)缓震地区是否具有某些可能使其容易发生海啸的特征；3)慢滑事件与深部偶发性震颤和地震滑动是否存在空间相关性。更广泛的影响该项目将支持两位早期职业女性pi，并将有助于理解两个MARGIN？S焦点站点。该提案还涉及ORRP的社会主题2：增强对自然灾害的抵御能力
