Determination of seismic notification to reduce seismic notification time of earthquake early warning system for artificial earthquake and natural earthquake

摘要

The present invention relates to an earthquake notification determination method performed in an earthquake early warning system for artificial earthquakes and natural earthquakes, which collects earthquake information measured in real time at each earthquake observatory through an integrated earthquake observation network, which comprises: a step of receiving new earthquake information renewed when a combination of new Assoc. observatories is added while a trigger observatory increases as a P-wave phase propagates from an epicenter (S100); and a step of quickly notifying an earthquake when the new earthquake information has a noticeable reliability and is determined as a quick earthquake notification by a logical condition considering spatial characteristics of the earthquake observatory and the magnitude of energy of P waves and S waves.
