Examining Changes in Earthquake Triggering Behavior Across the Ocean-Continent Transition, Gulf of California

国际和平研究所将研究加利福尼亚州海湾的地震活动，以确定哪种流变模型适用于该地区。分析的基础将是观察余震和前震的聚集，并将这些模式与热流、应力瞬变和地质的空间变化联系起来。PI之前曾研究过这一系统的两端，并认为加利福尼亚州海湾是寻找从海洋环境向大陆环境过渡的最佳地点。作为这项研究的前奏，国际地震研究所将为该地区编制一份地震目录，这对该地区的其他研究人员也很有用。广泛的影响包括对研究生的教育做出贡献。这项研究还有助于理解地震成核的物理学，了解地震中可能的震级序列将改善研究地区的实时危险性分析。

0548785McGuireAbstractThe PI will study seismicity in the Gulf of California to determine which rheological model applies to this region. The analysis will be based on observing the clustering of aftershocks and foreshocks, and relating these patterns to spatial variations in heat flow, stress transients, and geology. The PI has previously studied both ends of this system and views the Gulf of California as the best place to look for the transition from oceanic to continental environments. As a prelude to the study the PI will assemble an earthquake catalog for the region, which would also be useful to other researchers in the region.Broader impacts include contributing to education of a graduate student. This study also contributes to understanding the physics of earthquake nucleation and understanding the likely magnitude sequence in earthquakes will improve real-time hazard analysis in the study area.
