摘要
Earthquake early warning is defined as using the main indexes of earthquake prediction to calculate and analyze the urgency of a given-magnitude earthquake by the analytic hierarchy process(AHP) for a given region(or sub-region).We divide the North China into 3 earthquake-early-warning regions—the South,the Northwest,and the Northeast,and build early-warning models of indexes of regional seismic situations to determine 14 early-warning criterion in North China.Using AHP,and performing the calculation of indexes of seismic situations,we build an early-warning system of regional indexes and get the early warning level—Red,Orange,Yellow,and Blue for each earthquake by early-warning criterion.Finally,we check the early-warning system with the historical strong earthquake in North China and get the ideal result.
