Our limited understanding of the fundamental drivers behind earthquakes, tsunamis, volcanic eruptions, and landslides hinders our ability to anticipate these globally significant hazards. Subduction zones provide the opportunity to systematically investigate multiple hazards simultaneously in locations that generate some of the largest risk from geological events. In addition, the geometry of subduction zones permits unusually well-controlled natural experiments that can be used to isolate and study key factors driving geohazards. The study of subduction zones is intrinsically an international enterprise because: (1) Comparison across regions allows for insights about the controlling factors of the tectonic, volcanic and landscape systems. (2) Large geohazards are inherently rare events that require a portfolio approach globally to guarantee the correct observations are made systematically. Significant investments in subduction zone geohazards are now being made internationally. Active networks in Latin America, Europe, North America, Oceania and Asia are currently pursuing complementary science agendas and building large-scale deployments. Coordination between activities is needed to ensure that the maximum science is obtained from these efforts. SZNet would combine 14 networks across 5 continents with a particular emphasis on improving observations in Chile, which hosts one of the world’s most geologically active and accessible subduction zones. Multiple projects on and offshore are working to establish the large-scale data collection and research effort required to study this exemplary system and coordination is needed to optimize the scientific output both here and globally. The goal of SZNet is to develop an intellectual community with three missions:1. to compare observations of subduction zones around the globe with a common dataset and understanding,2. to cooperate to consistently instrument critical subduction zones that can provide key and transferrable insights, and3. to develop and nurture an international and diverse cadre of early career scientists that is equipped to make the necessary breakthroughs.These missions will be supported through a combination of workshops, webinars, data exchanges, field schools, pilot projects and student exchanges. We anticipate that these activities will allow a portfolio approach to observations to enable geographical coverage that will both create the necessary baseline data and maximize the chances of capturing earthquakes, volcanic eruptions and landslides. In addition, the exchange of ideas will benefit partner networks while stimulating coordinated deployment and research strategies. Understanding geohazards has direct societal significance for the inhabitants of the Pacific Rim and other subduction zones around the world. The lack of understanding of the fundamental controls on when and where impactful earthquakes, eruptions and landslides can happen is a major impediment to focussing resources and mitigation efforts. Developing this understanding through an international network would connect the disparate experiences and expertise of experts in each subduction zone to provide a unified framework through missions 1 and 2. Mission 3 would broaden the geoscience community by supporting international early career scientists with a program of field schools, pilot projects and student exchanges.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.

我们对地震，海啸，火山喷发和滑坡背后的基本驱动因素的了解有限，这阻碍了我们预测这些全球重大危害的能力。俯冲区为仅在地质事件中产生一些最大风险的位置提供了系统地研究多种危害的机会。此外，俯冲带的几何形状允许很少有能力控制的自然实验，这些实验可用于隔离和研究驱动地沙佳的关键因素。俯冲带的研究在本质上是国际企业，因为：（1）跨区域的比较允许有关构造，火山和景观系统的控制因素的见解。 （2）大的地球岩是固有的罕见事件，在全球范围内需要投资组合方法，以确保系统地进行正确的观察结果。现在，在国际上进行了俯冲区的大量投资。目前，拉丁美洲，欧洲，北美，大洋洲和亚洲的活动网络目前正在追求完整的科学议程并建立大规模部署。需要活动之间的协调以确保从这些努力中获得最大的科学。 SZNET将在5大洲的14个网络结合在一起，并特别强调改善智利的观察结果，智利拥有世界上最有活跃和易于使用的俯冲区之一。在海上和海上的多个项目正在努力建立研究此示例系统所需的大规模数据收集和研究工作，并且需要协调以优化这里和全球的科学输出。 SZNET的目标是开发一个具有三个任务的知识社区：1。为了比较全球俯冲带的观察结果与共同的数据集和理解2。合作以始终如一的仪器临界俯冲带，可以提供关键和可转让的见解和3。开发和护理一家国际和潜水员的早期职业科学家干部，等同于实现必要的突破。这些任务将通过研讨会，网络研讨会，数据交换，野外学校，试点项目和学生交流的结合来支持。我们预计这些活动将允许投资组合方法来观察，以实现地理位置。覆盖范围将创建必要的基线数据，并最大程度地捕获地震，火山喷发和滑坡的机会。此外，思想的交流将使合作伙伴网络受益，同时刺激协调的部署和研究策略。理解地球扎第斯山剂对环太平洋和世界其他俯冲区的影响者具有直接的社会意义。缺乏对何时何地发生有影响力的地震，喷发和滑坡的基本控制，这是集中资源和缓解努力的主要障碍。通过国际网络发展这种理解将连接每个俯冲区域中不同专家的经验和专家，通过任务1和2提供一个统一的框架。任务3将通过支持国际早期职业科学家通过实地学校，试点学校和学生交流的计划来扩大地球科学社区，这些奖项通过NSF的法定宣称和稳定的授权来表现出来，这反映了NSF的诚实构成的构成，这是诚实的构成，这是诚实的支持。 标准。
