两条历史记载的启迪对震前予位移机理和预警时间的探讨
Discussion on the Pre-earthquake Displacement Mechanism and Earthquake Early Warning Time Based on Inspiration of the Two Historical Records
摘要
Abstract
In this paper, two historical earthquakes are studied, because these two records have implications for further exploration of earthquake prediction, especially earthquake warning. One is a unique phenomenon of the historical earthquake - the rotation of the ground produced before the earthquake, according to the record, the paper analyzed its physical mechanism, and discussed whether it can be used as a precursor to the instructions. Another historical earthquake record is the time record between the major movement and the small movement before the earthquake, the record of the earthquake in the near field provides an early warning, because in the near field, from the source the P wave and S wave are not separated, then there is no time difference between the arrival of two waves, the paper does a preliminary discussion, and expects to provide reference for the determination of early warning time in earthquake zones关键词
