|Region:||Kamchatka and Mainland Asia|
|Measurement method(s):||GPS - continuous, Levelling|
|Duration of observation:||1970s to 1990s (levelling)|
|Inferred cause of deformation:||Magmatic, Uncertain|
|Characteristics of deformation:|
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 Longgang Volcanic Group, as well as the Wuclalianchi Volcanic Group and Chang-baishan Tianchi Volcano. They found that the “the Longgang volcanic area was inflating with a vertical velocity 3–4 mm/a (Figure 2), which indicates that magma or hydrothermal fluid intrusion events may occur beneath the volcano.”
