Seismogeodesy is a developing discipline jointing the seismology and tectonics with its ability of determining the geophysical field associated with earthquake-cycle,in which the measured deformation ranging in 10²a～10^-2s fills-up the gap between seismology and tectonics. The Crustal Movement Observation Network of China(CMONOC)composed with the multiple space geodesy technologies that are capable of broadband observations not only depicts the image of crustal deformation in China,but also plays an important role in measuring the displacement associated with the large earthquake,such as the 2008 Wenchuan earthquake,2013 Lushan earthquake,2015 Gorkha earthquake and 2017 Jiuzhaigou earthquake. For these above earthquakes the geodetic measurements from static/high rate GNSS,InSAR and Leveling construct the coseismic displacement field,and contribute to the studies of source kinematics,intraplate earthquake mechanism,and earthquake early warming. However,the limited resolution of CMONOC at present is not sufficient enough to develop demands of seismogeodesy,and the farther enhancement is needed.
