摘要
现代电子技术的应用使强震仪的功能大大加强,数字强震仪和电子通讯技术的应用使得地震预警能够实现。本文介绍了地震预警的传统方法和基于现代信息技术的地震预警理论和方法。以日本的UrEDAS为例,详细介绍了基于P波单台定位、定震级的方法。对我国开展相关研究具有借鉴意义。
Recent years, accelerographs have been greatly enhanced by applying the rapidly developing electronic technology. Earthquake early warning system has come true by the combination of digital accelerographs and modern communication technology in the past few years. This paper presents the basic theory and method of modern earthquake early warning system. A representative example of earthquake early warning System - UrEDAS of Japan which is based on single station determination of location and magnitude by using P wave is introduced in detail. The information here will be useful for the relevant research in our country.
