近来依靠地震传感器技术、数据接收数码通讯系统、计算机硬件与软件的快速发展，人们可以建立可靠的实时地震信息系统。这些系统为现代城市有效地处理大地震的灾害提供了新的手段，甚至能够在地震波到达前几秒钟发出警报。从长远看，这些系统也为如何改进建筑质量等减灾策略提 Recently, with the rapid development of seismic sensor technology, data receiving digital communication systems, computer hardware and software, people can build reliable real-time earthquake information systems. These systems provide new tools for modern cities to effectively deal with the devastating effects of major earthquakes and can even alert you to a few seconds before the arrival of seismic waves. In the long run, these systems also serve as mitigation strategies to improve building quality
