RAPID: Capture of ephemeral fault slip data from the North Anatolian slow slip event Dec2019 and triggered slip data from the East Anatolian Mw=6.8 earthquake

这个RAPID项目响应了土耳其安纳托利亚断层最近发生的两次事件，一次是5.4级慢地震，另一次是2020年1月发生的6.8级地震。了解这些事件很重要，因为它们会造成重大的生命损失，并对建筑物和基础设施造成破坏。此外，断层系统与加州的非常相似。通过收集这些事件前后测量形变的仪器的数据，提高我们对这次地震和缓慢滑动事件的理解，对于研究这个断层和许多其他断层的研究人员来说是有价值的。首席研究员将与土耳其当地研究人员合作，作为数据收集工作的一部分。美国社区将通过UNAVCO数据档案快速获得数据。该项目支持对安纳托利亚断层系统上连续发生的两起事件做出快速反应。首席调查员将从沿断层沿着的5个非遥测引伸计下载数据，并绘制破裂的表面表达。这些数据将是有价值的了解慢滑和地震断层运动的相互关系，了解事件成核和断层滑动。这场缓慢滑动的地震持续了一个月，导致北安纳托利亚断层显著滑动。这次6.8级地震破坏了东安纳托利亚断层80公里的一段。这项工作的更广泛影响包括与位于伊斯坦布尔的坎迪利天文台的研究人员的合作，提高了对地震危害的认识，并迅速向美国研究界提供数据。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 RAPID project responds to two recents events on the Anatolian fault in Turkey, a magnitude 5.4 slow earthquake and a magnitude 6.8 earthquake in January of 2020. These events are important to understand because they cause signifcant loss of life and damage to buildings and infrastructure. In addition, the fault system is very similar to those in California. Improving our understanding of this earthquake and slow slip event by collecting data from instruments that measure deformation immediately before and after these events is valuable for researchers studying this fault and many others. The lead investigator will be collaborating with local researchers in Turkey as part of this data collection effort. The US community will gain access to the data quickly through the UNAVCO data archive.This project supports rapid response to two events on the Anatolian fault system that happened in quick succession. The lead investigator will download data from 5 non-telemetered extensometers along the fault, and map surface expressions of the rupture. These data will be valuable in understanding slow slip and seismic fault motion in relation to each other, understanding event nucleation and fault slip. The slow slip earthquake persisted for a month causing the North Anatolian fault to slip significantly. The Mw 6.8 earthquake ruptured an 80km segment of the East Anatolian fault. The broader impacts of the work include collaboration with researchers at the Kandilli Observatory in Instanbul, improved understanding of earthquake hazards and rapid data availability to the US research community.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.
