The migration of seismicity refers to the sequential occurrence of earthquakes in a certain direction, which is the ordered structure in the local area in the overall disorder of seismicity. Through the systematic analysis of the typical seismic migration phenomena in the region, it can be found that the migrations can be divided into three categories:longitudinal migration along the fault strike, transverse migration along the vertical fault strike and deep source migration on the lithosphere scale. Combined with the analysis of specific examples, the main characteristics of vertical migration (including one-way, two-way, repeated and jumping migration), horizontal migration and deep source earthquake migration can be preliminarily summarized, and the velocity values of different types of migrations can be preliminarily estimated, among which the average velocity of vertical migration along the global plate boundary is about 569 km/a, the average velocity along the sub plate boundary is about 120 km/a, and the average velocity along the continental internal fault zone is about 34 km/a. The horizontal migration is relatively complex. It is found that there are two kinds of migration phenomena in East Asia, one is about 20 km/a, the other is about 50 km/a. The global average migration velocity of deep source earthquakes is about 360 km/a. There are different levels and grades of vertical and horizontal migration of earthquakes, and there are also many kinds of deformation waves and migration phenomena with different frequencies, energy and velocities, which may be the result of the interaction of interruption layers in the process of large earthquake clustering activity, the triggering of seismic stress and the propagation of deformation waves on the scale of lithosphere, and it is obvious that the existence and regularity of this kind of earthquake migration phenomenon on the scale of large space can provide new ideas and method reference for regional seismic risk analysis.
