Hainan Dao

Observations of Deformation

Volcano number:275001
Geodetic measurements?Yes
Deformation observation?Yes
Measurement method(s):InSAR
Duration of observation:2007-2011
Inferred cause(s) of deformation:Magmatic
Characteristics of deformation:

Ji et al. (2015) propose that the observed surface deformation pattern is due to a magma-fed dyke. This dyke is modeled to by approximately 54 km long, 1 km wide, dipping 71° to the west and 25 km beneath Hainan Island.
