This CAREER proposal seeks to make fundamental contributions in our understanding of earthquake interaction and fault slip behaviors through systematic analysis of earthquake triggering and "non-volcanic" tremor, based on the large seismic data collected from the EarthScope experiment and other permanent seismic networks in the US, and permanent and temporary seismic deployments in East Asia. The project will prepare next-generation seismologists to be capable of analyzing large seismic data through various training courses and research projects. The research results will be dissimilated to general public through sonification and visualization tools.The proposed tasks include:1. Early aftershocks. The researcher will detect and locate missing aftershocks immediately after the 2008 Mw7.9 Wenchuan earthquake in China, and several recent large earthquakes in California and Japan, using a waveform matched filter technique. The newly identified events will be used to test whether aftershocks are triggered by static or dynamic stresses, or other time-dependent mechanisms.2. Remote triggering: a systematic survey of remotely triggered seismicity in active regions in the Western US, and relatively stable intraplate regions such as Continental China and the Central and Eastern US. I hope to identify necessary conditions and constrain physical mechanisms for remote triggering in active and intraplate regions.3. Non-volcanic tremor: a systematic study of non-volcanic tremor, focusing on California and Taiwan. The obtained results will be used to better understand the physical mechanisms of tremor generation and how accumulated strain is released in seismic/aseismic events. 4. Training next-generation seismologists. The researcher will provide many undergraduate research opportunities through summer internship programs, and collaborations with researchers in undergraduate institutions. He will develop an online tutorial and training material for Seismic Analysis Code (SAC) and data management, which can be used to train senior undergraduate and incoming graduate students in Georgia Tech and other institutions.5. Sonification and visualization of seismic data. Research results on earthquake triggering and non-volcanic tremor will be made accessible to general public through sonification (i.e., making sounds from seismograms) and visualization. In addition, the PI will work with IRIS Education and Outreach (E&O) specialists to generate sounds and animations for significant events based on seismic data archived at the IRIS Data Management Center (DMC).

本CAREER提案旨在通过对地震触发和“非火山”震颤的系统分析，基于从EarthScope实验和美国其他永久性地震网络收集的大型地震数据，以及东亚的永久和临时地震部署，为我们理解地震相互作用和断层滑动行为做出根本性贡献。该项目将通过各种培训课程和研究项目培养下一代地震学家，使其能够分析大量地震数据。研究成果将透过有声化与视觉化工具，向大众进行异化。早期余震。研究人员将使用波形匹配滤波器技术检测和定位2008年中国汶川Mw7.9地震以及最近在加州和日本发生的几次大地震后的失踪余震。这些新发现的事件将被用来检验余震是由静态应力还是动态应力，或者其他与时间相关的机制触发的。远程触发：对美国西部活跃地区和相对稳定的板内地区（如中国大陆和美国中部和东部）的远程触发地震活动进行系统调查。我希望确定必要的条件和限制的物理机制，远程触发活动和板内区域。非火山性震颤：非火山性震颤的系统研究，以加州和台湾为重点。所获得的结果将被用来更好地理解震颤产生的物理机制和积累的应变是如何释放在地震/地震事件。4.培养下一代地震学家。研究人员将通过暑期实习计划以及与本科院校研究人员的合作提供许多本科研究机会。他将为地震分析规范（SAC）和数据管理开发在线教程和培训材料，可用于培训格鲁吉亚理工学院和其他机构的高年级本科生和即将入学的研究生。地震数据的声化和可视化。关于地震触发和非火山震颤的研究结果将通过声音处理（即，从地震图中发出声音）和可视化。此外，PI将与IRIS教育和推广（E O）专家合作，根据IRIS数据管理中心（DMC）存档的地震数据为重大事件生成声音和动画。
