Longgang Group

Volcano number:305050
Region:Kamchatka and Mainland Asia
Country:China
Geodetic measurements?Yes
Deformation observation?Yes
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.”
