The IRIS Consortium (Incorporated Research Institutions for Seismology) provides, via the "Seismological Facilities for the Advancement of Geoscience and EarthScope" (SAGE), a suite of community-governed, multi-user facilities for instrumentation and data management that support research and education in seismology and the Earth sciences. The facilities include a high-performance network of more than 150 permanent stations providing data for global studies of earthquakes and deep Earth structure; a mobile array of more than 400 seismometers and atmospheric sensors completing a traverse of the conterminous United States and deploying to Alaska; and more than 4000 portable instruments (including magnetotelluric systems) are available for short-and long-term loan to university-based researchers for detailed studies as part of NSF-funded field programs. Future observing needs are being addressed via systematic engineering efforts. Data from all of these observational systems, along with extensive collections of seismic data contributed by other organizations, are freely and openly available through the IRIS Data Management Center.Data collected and distributed through IRIS facilities form the observational basis for most of the fundamental studies in seismology carried out by researchers at US universities and in many organizations worldwide. The stability and high quality of the permanent observatories capture both the short-term details of faulting during the seconds to minutes of rupture in major earthquakes as well as decadal-scale changes in global earthquake activity. Data from permanent, mobile, and portable arrays are used to resolve features in Earth structure over scales that range from the whole Earth, to lithosphere, to regional basins, to fault zones. These data provide fundamental information on Earth structure and processes that, in combination with other geoscience disciplines, contribute to enhanced understanding of how the active Earth evolves and deforms. As a part of EarthScope, these observations contribute to multidisciplinary studies that focus on the structure and dynamics of North America and contribute to unraveling the history of deformation of the continent. The IRIS program in Education and Public Outreach directly links the public and schools with the activities of an academic research community by demonstrating how basic seismological observations are made and used in Earth science investigations. Through a variety of activities that extend from the provision of classroom and web resources, to museum displays, public lectures, and internships, IRIS encourages students to engage in scientific inquiry and appreciate the importance of the Earth sciences in their lives. In addition to supporting fundamental research, the seismological resources provided by IRIS serve dual use by contributing directly to societal needs through reporting of global earthquake activity and applications in monitoring nuclear test ban treaties. Scientific and technical outreach by IRIS and its members as part of their international activities also provides assistance and guidance in the development and implementation of earthquake monitoring networks and hazard assessment, especially in developing countries.

IRIS联盟（地震学的成立研究机构）通过“地球科学和地球科学的发展”（SAGE）（SAGE）提供了一套由社区管理的仪器和数据管理设施，以支持地震学和地球科学领域的研究和教育。这些设施包括一个高性能网络，该网络由150多个永久电台组成，提供了用于全球地震和深层地球结构研究的数据；一个超过400个地震仪和大气传感器的移动阵列完成了美国的遍历并部署到阿拉斯加；作为NSF资助的现场计划的一部分，可以向大学研究人员短期贷款和长期贷款，并长期向大学研究人员提供短期贷款和长期贷款。未来的观察需求正在通过系统的工程工作解决。来自所有这些观察系统的数据，以及其他组织贡献的大量地震数据收集，可以通过IRIS数据管理中心自由公开地获得。通过IRIS设施收集和分发的数据构成了大多数基本研究的观察基础，这些基础研究是由美国大学和许多组织在世界各地的地震学进行的。永久天文台的稳定性和高质量捕获了主要地震中断层到几分钟内断层的短期细节，以及全球地震活动的十年阶段变化。从永久，移动和便携式阵列中的数据用于解决地球结构中的特征，从整个地球到岩石圈，再到区域盆地，再到断层区域。这些数据提供了有关地球结构和过程的基本信息，这些信息与其他地球科学学科结合在一起，有助于增强对活动地球如何发展和变形的理解。作为Earthscope的一部分，这些观察结果有助于多学科研究，这些研究的重点是北美的结构和动态，并有助于揭示非洲大陆变形的历史。 IRIS教育和公众宣传方面的计划通过证明如何在地球科学调查中进行基本的地震学观察结果，将公众和学校与学术研究界的活动联系起来。通过各种活动，从提供教室和网络资源，到博物馆展示，公开讲座和实习，Iris鼓励学生进行科学探究，并欣赏地球科学在生活中的重要性。除了支持基本研究外，虹膜提供的地震资源通过报告全球地震活动和监测禁令核试验禁令条约的应用来直接促进社会需求，从而提供双重使用。 IRIS及其成员作为其国际活动的一部分的科学技术宣传还为地震监测网络的发展和实施提供了帮助和指导，尤其是在发展中国家。
