Query: Common dependence on earthquake magnitudes for the trapped particles
  bursts approaching the earthquake   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.
