As one important part of seismic data acquisition system, on-site digitalrecording system not only can monitor and process field seismic data in time but also can control recording quality.
Before several M5.0 earthquakes from 2001, the wave recording data of the deformation digital observation show the clear changes in seismic station of Houma, Shanxi Province.
