Experts from the strong motion observation group in the China Earthquake Administration are in charge of maintenance and operations, data collection, processing, storage and management, and providing Internet data services for the Network. The experts from the Seismological Bureaus of Provinces of Sichuan, Gansu, Shaanxi, etc., and the Institute of Engineering Mechanics made an effort to collect all the recorded data and process them after the main shock of the Wenchuan Earthquake. The authors of the present article are very grateful to the efforts by all the officers and experts who contributed to the success in obtaining the recorded data in the Wenchuan Earthquake.

中文摘要：

中国的国家强壮的运动观测站网系统(NSMONS ) 简短在这篇论文被介绍。NSMONS 由永久免费地的车站，特殊观察数组，活动天文台和一个网络管理系统组成。在 Wenchuan 地震期间，加速记录的超过 1,400 个部件从主要吃惊在网络系统为地形学的效果和结构的反应观察从 460 个永久免费地的车站和三个数组被获得，并且从强壮的余震的加速记录的超过 20,000 个部件发生在8月1日前， 2008 也由 NSMONS 和快速在主要吃惊以后部署的 59 台活动仪器的永久免费地的车站被获得。从主要吃惊和强壮的余震的强壮的运动记录在这篇论文被总结。在扎根的运动记录，在 10 女郎上有有山峰地面加速(针网阵列) 的超过 560 个部件，最大是 957.7 女郎。在余震期间记录的最大的针网阵列超过 300 女郎。

英文摘要：

The National Strong Motion Observation Network System （NSMONS） of China is briefly introduced in this paper. The NSMONS consists of permanent free-field stations, special observation arrays, mobile observatories and a network management system. During the Wenchuan Earthquake, over 1,400 components of acceleration records were obtained from 460 permanent free-field stations and three arrays for topographical effect and structural response observation in the network system from the main shock, and over 20,000 components of acceleration records from strong aftershocks occurred before August 1, 2008 were also obtained by permanent free-field stations of the NSMONS and 59 mobile instruments quickly deployed after the main shock. The strong motion recordings from the main shock and strong aftershocks are summarized in this paper. In the ground motion recordings, there are over 560 components with peak ground acceleration （PGA） over 10 Gal, the largest being 957.7 Gal. The largest PGA recorded during the aftershock exceeds 300 Gal.
