This MRI award will provide funding to establish a network of ten first-order geophysical observatories, with co-located broadband seismic, strong motion, infrasound, barometric pressure and meteorological (temperature, pressure, wind speed and direction, precipitation and relative humidity) sensors at approximately 350 km spacing along the length of Chile, in one of the world's most dynamic geosystems. This backbone network, coupled with planned upgrades to the Chilean National Seismic System, will form the basis for improved understanding of the structure and dynamics of the boundary between the Nazca and South American plates; the origin of large subduction zone earthquakes; pre-, co- and post-seismic deformation; earthquake activity throughout Chile, South America and the southeastern Pacific; comparative studies with subduction zones in similar tectonic settings; infrasound signals from regional Andean volcanoes and other atmospheric disturbances; and atmospheric dynamics between the western edge of the Andean Mountains and the Pacific Ocean. This collaborative effort between the IRIS Consortium and the University of Chile, with a commitment to free and open distribution of all data, will stimulate opportunities for enhanced research and education across fundamental geoscience disciplines and in hazard mitigation. This collaborative effort in infrastructure development establishes a promising model for the engagement of the US academic community in the development of modern observational systems, which may be emulated in neighboring parts of South America and throughout the world.

该核磁共振奖将提供资金，用于建立一个由10个一级地球物理观测站组成的网络，在智利这个世界上最具活力的地球系统之一，沿着智利的长度，在大约350公里的间距上，共同设置宽带地震、强震、次声、气压和气象（温度、压力、风速和风向、降水和相对湿度）传感器。这个主干网络，加上智利国家地震系统的计划升级，将形成对纳斯卡和南美板块之间边界的结构和动力学更好理解的基础；大俯冲带地震的成因；地震前、地震共、地震后变形；智利、南美洲和东南太平洋的地震活动；与类似构造背景下俯冲带的对比研究；来自安第斯火山和其他大气扰动的次声信号；以及安第斯山脉西部边缘和太平洋之间的大气动力学。IRIS联盟与智利大学之间的这一合作努力，承诺免费和开放地分发所有数据，将为加强地球科学基础学科和减灾方面的研究和教育创造机会。这种在基础设施发展方面的合作努力为美国学术界参与现代观测系统的发展建立了一个有希望的模式，可以在南美洲邻近地区和全世界效仿。
