Common dependence on earthquake magnitudes for the trapped particles bursts approaching the earthquake

TL;DR

This study investigates the relationship between earthquake magnitudes and trapped particle bursts, showing consistent dependence and decay patterns that support their potential as earthquake precursors.

Contribution

It provides the first systematic analysis of particle burst frequency distribution and decay behavior across different earthquake magnitudes.

Findings

Particle burst frequency correlates with earthquake magnitude.

Particle bursts exhibit characteristic time decay.

Findings support particle bursts as earthquake precursors.

Abstract

Trapped particles bursts have long been observed to be frequently occurred several hours before earthquakes, especially for strong earthquakes, from several space experiments during past decades. However, the validity of earthquake origin of particles bursts events is still unsolved. In this paper, we firstly reported the frequency distribution and time evolution of particles bursts within different time windows centered around earthquakes for various magnitudes. The results showed nearly the same systematic dependence of particle bursts frequency on earthquake magnitude and characteristic time decay behavior of average number of particles bursts for various magnitudes. These findings should strengthen the validity of earthquake origin of particles bursts and further understanding of particles bursts as possible precursor of earthquake.
