Advances and Overview of the Study on Paleo‐earthquake Events: A Review of Seismites

AbstractThe distribution and formation mechanisms of typical identified seismites are analyzed based on various factors from plate tectonic positions, types of sedimentary basins and properties of seismogenic faults to focal mechanisms. Especially, structural styles, reserved positions, activity times, formation mechanisms and dynamics of soft‐sediment deformation structures triggered by seismic activity are systematically analyzed. According to the genetic types of seismites, we propose 5 categories, including liquefied deformation, thixotropic deformation, hydroplastic deformation, superimposed gravity driving deformation and brittle deformation. Further, based on the main genetic types, composition of sediments and deformation styles, we draw up 35 secondary classifications. To determine paleo‐seismic sequences in different times, activities of seismogenic faults, high‐resolution tectonic events in one main tectonic movement and paleo‐tectonic settings, and to understand the inducing mechanisms of paleo‐earthquakes and ecologic environment evolution, researching on seismites are of great significance. Combing multiple approaches to identify the paleoearthquake records, simulating experiments on various soft‐sediment deformation structures triggered by different magnitudes of shocking, dating precisely on paleo‐seismic events, impacting on paleogeography and biological environment and on energy and resources domain are the frontiers of paleoseismic research.
