Collaborative Research: Defining locations and patch sizes for slow earthquake ruptures in subduction zones

这项工作的学术价值在于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，PI将研究以下问题：1)已知的海啸发源区是否发生慢地震；2)慢地震地区是否具有可能导致海啸发生的某些特征；以及3)慢滑事件与深幕地震和无地震滑动之间是否存在空间相关性。更广泛的影响该项目将支持两个职业生涯早期的女性PI，并将有助于理解两个边缘？S焦点站点。这项建议还涉及ORRP的社会主题2：提高对自然灾害的复原力

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.
