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

拟议的工作是扩大、更新和延长哥斯达黎加尼科亚半岛现有全球定位系统和地震仪器网络的监测期。所收集的数据需要解决的问题包括：1）慢滑动、地震、应变积累与板间地震的关系。2)温度和流体在震颤和滑动产生中的作用是什么？3)快滑和慢滑震颤的发生是否在空间和/或时间上分开？这些问题的答案对理解俯冲带的地震过程具有重要意义。学生它还包括向哥斯达黎加转让技术和科学，以改善其对地震的监测。PI建议前往2所少数民族院校招生。

Intellectual MeritThe 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 ImpactsThis 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.
