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.

地震捕捉网络（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，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上。利用一套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，可以实时探索地震断层破裂，建立地震波通过的地面响应，并量化地震对关键结构的影响。美国国家科学基金会网络基础设施教学、教育、进步和指导项目为期一年的探索性资助的结果表明，QCN有能力成为一种新型的变革性网络，可扩展且易于在全球部署。将QCN传感器的数量从全球的1,000个增加到30,000多个，并开发有效的方案来摄取，处理和分发tb级的数据，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，滑移分布和破裂速度），(2)研究地面运动以评估地震危害和建筑反应，(3)实时分析数据以进行地震预警和快速反应。这一提议将使网络拥有6000个新的USB传感器和数万个通常内置在笔记本电脑和其他设备内部的免费传感器。此外，QCN将提供网络基础设施，以近乎实时的方式处理和分析大型新地震数据集，并促进1000？世界各地的研究人员和感兴趣的参与者。该项目奠定的框架将使网络能够在国际上快速扩展，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发展网络，为扩大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广泛参与有着内在的联系；公众成员，学校（K-12，本科生和研究生）和社区组织主办QCN传感器。这些平民科学家?将接收实时地震信息、地震数据和结果，以及互动式教育材料。
