Real-time Monitoring of Co-seismic Deformation with RTNet

Real-time GNSS network can be used to monitor seismic waves. The advantage of GNSS observation is that GNSS solution is not acceleration but positions of GNSS antenna, and GNSS works even in strong earthquake cases, as shown in the case of 2011 Tohoku earthquake in Japan.
