Collaborative Research: A Plate Boundary Observatory on the Nicoya Peninsula, Costa Rica

拟议的工作是扩大、升级和延长哥斯达黎加尼科亚半岛现有的GPS和地震仪器网络的监测期限。收集到的数据需要解决的问题包括：1)慢滑、震颤、应变积累与板间地震之间的关系是什么？2)温度和流体在震颤和滑动产生中的作用是什么？3)快滑和慢滑的发生在空间和/或时间上是分开的吗？这些问题的答案对于理解俯冲带的地震过程具有重要意义。本项目包括培养几名博士生。它还包括向哥斯达黎加转让技术和科学，以改善他们对地震的监测。ppi建议前往两所少数民族院校招生。

Intellectual Merit The work proposed is to augment, upgrade and extend the monitoring period of an existing network of GPS and seismic instrumentation on the Nicoya Peninsula, Costa Rica. The questions to be addressed by the data collected include: 1) What is the relationship between slow slip, tremor, strain accumulation and interplate earthquakes. 2) What is the role of temperature and fluids in tremor and slip generation? 3) Is the occurrence of fast and slow slip tremor spatially and/or temporally separated? The answers to these questions have important implications for understanding seismic processes at subduction zones. Broader Impacts This project includes the training of several Ph.D. students. It also includes technology and science transfer to Costa Rica to improve their monitoring of earthquakes. The PIs propose to travel to 2 minority institutions to recruit students.
