Abstract

The present invention provides a magnitude prediction method used for earthquake early warning. The magnitude prediction method corrects a predicted deviation generated in a fitted magnitude prediction formula, thereby substantially improving the magnitude prediction precision, and accurately predicting the magnitudes of the earthquakes. The magnitude prediction method has the important guiding significance for the magnitude prediction of the future earthquakes, especially the large earthquakes.

Description

technical field [0001] The invention relates to the technical field of earthquake engineering. More specifically, it relates to a magnitude prediction method for earthquake early warning. Background technique [0002] Earthquake early warning, as one of the important means to effectively reduce earthquake disasters, has been tried to be applied to lifeline projects and high-risk industries including high-speed rail. P-wave (P-wave or primary wave) is two kinds of body waves (the name of the body wave is because this wave passes through the interior of the earth, relative to the body wave is the surface wave, and the other body wave is the S wave (secondary wave)) One of. P wave means (primary wave) or pressure wave (pressure wave). Among all seismic waves, P wave has the fastest transmission speed, so when an earthquake occurs, P wave is the first seismic wave to arrive at the station and be recorded by the seismograph. Therefore, in the field of earthquake early warning...
