摘要：Emergent events and the chain reaction caused by them usually result in
   significant casualties and property losses.Herein,different emergency
   evolution models were studied from the systematic perspective to find
   out common characters and correlations of four various emergency
   events.An academic framework with four hierarchies,i.e.single
   event,event chain,event network,and event super-network,were
   proposed.Corresponding detail analysis was conducted.The effectiveness
   of the framework was verified through a real case.This paper can provide
   a reference to disaster prevention and early warning.
