International Workshop on Numerical Modeling of Earthquake Motions: Waves and Ruptures, Smolenice, Slovakia June 30-July 4, 2019

这是一个旅行奖，以促进参与地震运动的数值模拟：波和破裂研讨会在斯洛伐克主办的索尔瓦克科学院。地震破裂动力学和地面运动模拟是地震学和地震工程的核心内容。欧洲、亚洲和世界其他地区都有许多优秀的与震源有关的研究。国际科学交流有助于提高生产力和卓越水平，并培养下一代地震学家和震源过程和计算地震学专家。这项旅行计划的资金将支持大约24名美国学生、早期职业科学家和代表性不足的团体的成员。地面运动模拟和最近的动态破裂建模是地震危险性计算和震源过程研究的核心。广泛的数值方法正在使用，并有越来越多的努力来执行验证和验证的模拟代码。此外，研究人员现在正在定期进行实际地震和慢滑事件的动态破裂模拟，解决有关破裂如何导航断层几何复杂性的问题;摩擦，孔隙流体压力，非弹性材料响应和动态弱化机制对破裂成核，传播和逮捕的作用;这个国际研讨会将汇集来自不同国家的模型制作者与观测地震学家和实验家，促进科学知识和思想的交流。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This is a travel award to promote participation in the Numerical modeling of earthquake motions: waves and ruptures workshop in Slovakia hosted by the Solvak Academy of Sciences. Earthquake rupture dynamics and ground motion simulation are central to seismology and earthquake engineering. Much excellent earthquake-source-related research occurs in Europe, Asia, and the rest of the world. International scientific exchange serves to enhance productivity and excellence, as well as train the next generation of seismologists and experts in earthquake source processes and computational seismology. Funding in this travel proposal will support approximately 24 U.S. students, early career scientists, and members of underrepresented groups.Ground motion simulation and, more recently, dynamic rupture modeling are at the heart of seismic hazard calculations and studies of earthquake source processes. A wide range of numerical methods are being used, and there are growing efforts to perform verification and validation of the simulation codes. In addition, researchers are now routinely performing dynamic rupture simulations of actual earthquakes and slow slip events, addressing questions about how ruptures navigate fault geometric complexities; the role of friction, pore fluid pressure, inelastic material response, and dynamic weakening mechanisms on rupture nucleation, propagation, and arrest; etc. This international workshop will bring together modelers from different countries with observational seismologists and experimentalists, facilitating exchange of scientific knowledge and ideas.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
