Lingyun et al. (2014) present “a broad view of present-day 3D deformation field around the Northeast China region was derived from GPS and leveling observations”. 
The authors analyzed the vertical deformation surrounding the Wuclalianchi Volcanic Group using specifically levelling data, as well as the Longgang Volcanic Group, and Chang-baishan Tianchi Volcano. They found that the “Wudalianchi Volcanic Group was subsiding with a large velocity, which is consistent with its surrounding areas” (Figures 1 and 2; levelling results).
