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 MRI 奖项将提供资金建立一个由 10 个一级地球物理观测站组成的网络，并配备同位宽带地震、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）传感器沿智利长度约 350 公里间隔，位于世界上最具活力的地质系统之一。该骨干网络，加上计划中的智利国家地震系统升级，将为更好地了解纳斯卡和南美板块之间边界的结构和动态奠定基础；大俯冲带地震的起源；震前、震中和震后变形；整个智利、南美洲和东南太平洋的地震活动；与类似构造环境中的俯冲带进行比较研究；来自安第斯地区火山和其他大气扰动的次声信号；以及安第斯山脉西缘和太平洋之间的大气动力学。 IRIS 联盟和智利大学之间的合作致力于免费和开放地分发所有数据，将激发加强基础地球科学学科和减灾研究和教育的机会。这种基础设施开发方面的合作努力为美国学术界参与现代观测系统的开发建立了一个有前景的模式，南美洲邻近地区和全世界都可以效仿。
