Embodiment Construction

[0019] The new earthquake early warning method, which takes into account the advantages of the local method early warning and the remote method early warning, is realized on the basis of the remote method monitoring and early warning network. The key monitoring areas within the monitoring range are equipped with a number of on-site early warning and monitoring instruments Bj;

[0020] The method comprises the steps of:

[0021] Monitoring information interaction steps; a. The on-site early warning monitor Bj that detects the earthquake and the other adjacent on-site early warning monitors Bj perform earthquake information interactive communication; b. The on-site early warning that monitors the earthquake The seismic information interactive communication between the monitoring instrument Bj and the seismic monitoring instrument Ai located in its surrounding area; at the same time, the on-site early warning monitoring instrument Bj that has detected the occurrence of the earthq...

Abstract

The invention relates to the field of earthquake monitoring and early warning, in particular to a novel earthquake early warning method having advantages of on-site early warning and front-detection early warning. By the method, the problems that the position of earthquake epicenter cannot be pre-estimated by the conventional on-site earthquake early warning method and an early warning dead zone exists in the conventional front-detection earthquake early warning method can be solved. The method is implemented on the basis of a front-detection monitoring and early warning network and a plurality of on-site early warning monitors Bj. The method comprises the following steps of: interacting monitoring information; determining and executing early warning; and defining a range and executing the early warning. The method has the advantages of the front-detection early warning and the on-site early warning, so the early warning dead zone within a range covered by the front-detection earthquake monitoring and early warning network is eliminated effectively, and early warning signals can be provided in a meizoseismal area; furthermore, favorable early warning measures are provided for earthquake protection of important monitoring areas within a monitoring range, and the requirement of people such as unceasing enterprise on the earthquake natural disaster reduction science and technology can be met.

Description

technical field [0001] The invention relates to the field of earthquake monitoring and early warning, in particular to a novel earthquake early warning method that takes into account the advantages of the local early warning method and the remote method early warning method. Background technique [0002] Earthquake is a very destructive natural disaster. The Wenchuan Earthquake in 2008 and the Yushu Earthquake in 2010 have both witnessed its powerful and unpredictable destructive power. [0003] Seismic waves caused by earthquakes include seismic phases such as longitudinal waves, shear waves, and surface waves. Generally speaking, seismic longitudinal waves are not destructive, but seismic shear waves and surface waves are destructive. In view of the fact that the velocity of the seismic shear wave is slower than that of the seismic longitudinal wave, and the latter is much slower than the radio wave, as early as 1868, some American seismologists proposed to use the differ...
