Center for Engineering Strong Motion Data

Strong-motion data of engineering and scientific importance from the United States and other seismically active countries are served through the Center for Engineering Strong Motion Data(CESMD). The CESMD now automatically posts strong-motion data from an increasing number of seismic stations in California within a few minutes following an earthquake as an InternetQuick Report(IQR). As appropriate,IQRs are updated by more comprehensive Internet Data Reports that include reviewed versions of the data and maps showing, for example, the finite fault rupture along with the distribution of recording stations. Automated processing of strong-motion data will be extended to post the strong-motion records of the regional seismic networks of the Advanced National Seismic System (ANSS) outside California.

美国及其他地震活跃国家的工程与科学重要强震数据，由工程强震数据中心（Center for Engineering Strong Motion Data，简称CESMD）提供。CESMD现自动发布加州不断增加的地震台站的强震数据，作为互联网快速报告（Internet Quick Report，简称IQR），在地震发生后数分钟内即可获取。根据需要，IQR将通过包含经过审查的数据和展示如有限断层破裂以及记录站分布等信息的互联网数据报告进行更新。强震数据的自动化处理将被扩展，以发布加利福尼亚州以外区域地震网络系统的强震记录。
