Abstract
This paper introduces the design of a portable wireless-linked seismograph used in aftershock ultra-dense seismic array observation, which features easy-to-install, low-power consumption, real-time data transmission and remote control capability. Compared to traditional instruments, such as the combination of Reftek 130s data recorder and Guralp CMG-40T seismometer for China Seismic Array Program, it integrates the seismic sensor, seismic data recording unit, GPS timing service and wireless data link into a compact sealed housing. To verify the system’s functionality, both laboratory testing and preliminary field experiments were conducted. The exceptional feature of this newly-developed portable wireless-linked seismograph makes it very suitable for aftershock seismic array observation.
