Collaborative Research: CDI-Type II: From Data to Knowledge: The Quake-Catcher Network

地震捕手网络(QCN)是地震探测、科学和外展的一种变革性方法。QCN是一个分布式计算项目，它将内部(免费、内置)或外部(低成本、基于USB的)加速度计连接到任何参与地震研究的计算机。利用一组创新的网络地震观测，这种方法将能够创建一个非常密集、低成本的地震网络，可以实时探测地震断层破裂，建立对地震波通道的地面响应，并量化对关键结构的震动影响。来自NSF网络基础设施教学、教育、促进和指导计划的为期一年的探索性拨款结果表明，QCN有能力成为一种新型的变革性网络，该网络可扩展，并易于在全球范围内部署。将全球QCN传感器的数量从1,000个增加到30,000多个，并开发高效的方案来摄取、处理和分发TB级的数据，这将使我们能够(1)以前所未有的分辨率探索断层力学(包括方向性、滑动分布和破裂速度)，(2)研究地面运动以评估地震危险和建筑物响应，(3)实时分析数据，以便进行地震预警和快速反应。这项提议将导致网络中有6000个新的USB传感器和数万个免费传感器，这些传感器通常内置在笔记本电脑和其他设备中。此外，QCN将提供网络基础设施，以近实时地处理和分析新的大型地震数据集，并促进1000？S研究人员和世界各地感兴趣的参与者之间的合作。该项目建立的框架将使网络在国际上迅速扩展，并使我们能够以传统地震仪器和基础设施的一小部分成本来扩大网络，为增强现有的地震网络提供有价值的数据。地震捕手网络的成功与公众的更广泛参与内在地联系在一起；公众、学校(K-12、本科生和研究生)和社区组织托管QCN传感器。这些？公民科学家？将接收实时地震信息、地震数据和结果以及互动教育材料。

The Quake-Catcher Network (QCN) is a transformative approach to earthquake detection, science, and outreach. The QCN is a distributed computing project that links internal (no cost, built-in) or external (low cost, USB-based) accelerometers connected to any participating computer for earthquake research.Leveraging an innovative set of cyber-enabled seismic observations, this approach will enable the creation of a very dense, low-cost seismic network that can explore earthquake fault rupture in real-time, establish ground response to seismic wave passage, and quantify the shaking effects on critical structures. Results from a one-year exploratory grant from the NSF Cyber-Infrastructure Teaching, Education, Advancement and Mentoring program indicate QCN has the ability to be a new and transformative type of network, which is scalable and easy to deploy world-wide. Increasing the number of QCN sensors from 1,000 to more than 30,000 worldwide and developing efficient schemes to ingest, process, and distribute Terabytes of data will allow us to (1) explore fault mechanics (including directionality, slip distribution, and rupture velocity) at unprecedented resolutions, (2) study ground motions to assess seismic hazard and building response and (3) analyze data in real time for earthquake early warning and rapid response. This proposal will result in network with 6,000 new USB sensors and tens of thousands of no-cost sensorscommonly built internal to laptops and other devices. Additionally, QCN will provide the cyberinfrastructure to process and analyze the large new seismic data sets in near-real time and to foster collaboration between 1000?s of researchers and interested participants around the world. The frameworklaid by this project will enable rapid expansion of the network internationally and will allow us to grow the network at a fraction of the cost of traditional seismic instrumentation and infrastructure, providing valuable data to augment the existing seismic networks.The success of the Quake-Catcher Network is intrinsically linked to the broader participation of the general public; members of the public, schools (K-12, undergraduate and graduate), and community organizations host QCN sensors. These ?citizen-scientists? will receive real-time earthquake information, seismic data and results, and interactive educational materials.
