Abstract

As one of the effective ways to mitigate earthquake hazards, earthquake early warning (EEW) has been studies by many countries and regions around the world and significant mitigation effectiveness has been achieved during practical application. However, the data format for real-time data transmission in these EEW systems is organized as one packet per second which will lead to certain day when using first three seconds P wave data for c&Pd calculation. In this case, if P wave arrival of an earthquake is at the first half of a packet, the data latency will be more than 0.5 s. To address this problem, we develop a new type of seismic recorder called EDAS-24GN with low-latency real-time data output for EEW. It can transfer real-time data by one packet per 0.1 s so that the leading time can be improved with 0.8 s at maximum. This will be very useful for areas close to the epicenter.
