Abstract
The classification of earthquake early warning (EEW) system is divided into two major approaches. One is the regional warning and the other is the onsite warning. With the dense real-time earthquake monitoring ne-twork established in Taiwan, the EEW system has a strong base to dev-elop. A remarkable progress in the past decade was that the regional EEW system with virtual subnetwork could send the real-time earthquake wa-rning messamges within 20 seconds after an event occurred the regional EEW system with a virtual subnetwork approach. Another EEW-onsite EEW approach using the first 3 sec of P waves has been developed and been under online experimentation., Integrating regional and onsite sy-stems may enable EEW messages to be issued within 10 sec after an e-vent occured in the near future. This study mainly discusses the metho-dology of determining the magnitude and ground motion of an event. In addition, this presentation will show other relevant studies to added to explain the different situation of these applications.
