Operation of a Strong Ground Motion Array in the New Madrid Seismic Zone

新马德里地区提供了北美东部收集数据的最佳机会之一，这些数据可以帮助解决对地震危险评估至关重要的问题。自1988年以来，哥伦比亚大学的拉蒙特·多尔蒂地震观测站在新马德里地震区(NMSZ)运行了一个强地面运动台网。其目的是收集和传播地震数据，用于减轻地震危险。该阵列产生数据，用于研究波的传播，并解决与该地区地震危险有关的问题。它还提供了关于重大工程问题的数据；特别是现场响应和衰减。这一行动是为了补充现有的USGS支持的站点，以支持更多的仪器，以及相关的操作、维护和通信成本。这将产生一个20个站点的配置，有8个站点可通过电话访问。它还包括部分支持，以统一来自NSF支持和USGS支持的网络组件的数据流。

The New Madrid region provides one of the best opportunities in eastern North America to collect data that can help to resolve issues critical to seismic hazard assessment. Since 1988, Columbia University's Lamont Doherty Earthquake Observatory has operated a network of strong ground motion stations in the New Madrid Seismic Zone (NMSZ). The objective is to collect and disseminate seismic data for use in earthquake hazard mitigation.The array produces data for studying wave propagation, and for addressing the issues relevant to the seismic hazard in the region. It also provides data regarding significant engineering problems; especially site response and attenuation.This action is to supplement the existing USGS-supported stations with support for additional instruments, together with the associated operation, maintenance and communication costs. This will yield a 20-station configuration, with 8 stations accessible via telephone. It also includes partial support to unify the data streams from both the NSF-supported and USGS-supported components of the network.
