传统地震预警方法通过在地震频发区域部署高密度地震监测台网,进而构建区域地震预警系统。但此方法所需投资较高,同时还需要政府和不同行业间的密切合作,使得大部分位于地震频发区域的国家和地区无力支撑地震预警系统的建设与运维。随着微机电系统技术的发展以及智能手机的普及,地震预警技术出现了新的研究方向,利用智能手机开展地震预警具有巨大的发展潜力。迄今为止,国内外已研发完成多款诸如MyShake、i-jishin之类的手机端APP地震预警软件。本文详细描述了利用手机端内嵌MEMS芯片开展地震预警的研究进展,较为系统地总结了在手机端进行地震预警时所涉及的处理流程以及相关算法。

The traditional earthquake early warning method builds a regional earthquake early warning system by deploying a high-density seismic monitoring network in areas with frequent earthquakes. However,this method requires high cost and also involves close cooperation between the government and different industries. This factor makes most countries and regions located in earthquake-prone areas unable to support the construction and operation of earthquake early warning systems. With the development of Micro-Electro-Mechanical System(MEMS) technology and the popularization of smart phones,a new research direction of earthquake early warning technology has emerged,and the use of smart phones to carry out earthquake early warning has great potential for development. So far,a number of mobile phone APPs earthquake early warning software such as MyShake and i-jishin have been developed at home and abroad. This paper describes in detail the research progress of earthquake early warning using embedded MEMS chips on mobile phones,and systematically summarizes the steps and related algorithms involved in earthquake early warning on mobile phones.
