Abstract

The invention discloses a method for predicting an earthquake by monitoring variation of VLF electromagnetic radiation intensity. The method is characterized by comprising the steps that (1), a crossed grid monitoring network is established in a target zone; (2), electromagnetic signal receivers of three components of x, y and z are placed on monitoring points of the crossed grid monitoring network; (3), received VLF signals are transmitted to a data analyzing system wirelessly through a data transmission system by the electromagnetic signal receivers; (4), received VLF information is instantly analyzed and processed by the data analysis system and transmitted to an imaging monitoring center in different manners; (5), the signals received by the imaging monitoring centers are displayed inreal time, and alarms are sent. The method has the advantages that the variation of spatial and underground VLF radiation intensity is sensed and received by the electromagnetic signal receivers, andtherefore early prediction of the earthquake is achieved.

Description

technical field [0001] The invention relates to the technical field of earthquake monitoring and forecasting, in particular to a method for forecasting earthquakes by monitoring changes in VLF electromagnetic radiation intensity. Background technique [0002] Earthquake prediction is the ability to accurately predict the location, time, and magnitude of an earthquake before an earthquake occurs, that is, the three elements of an earthquake. This can greatly avoid the casualties caused by the occurrence of a large earthquake in unknown circumstances. The research on earthquake prediction has always been focus on. Seismic experts at home and abroad study the geological structure, crustal movement, etc. and expect to discover the mechanism of earthquakes. With the help of the development of information science, they develop observation instruments and establish disciplines for seismology, crustal deformation, electromagnetics, subsurface fluids, and auxiliary observations. and...
