Observations of Deformation

Volcano number:355100
Geodetic measurements?Yes
Deformation observation?Yes
Measurement method(s):InSAR
Duration of observation:1992-2000
Inferred cause(s) of deformation:Uncertain
Characteristics of deformation:

The deformation has spatial dimension of 500 by 400 m and relates to a subsidence of crater floor up to 17 mm. Interpreted to be due of change at crater pressure. Ref 2
Pritchard et at. 2002 published that there was no deformation observed at this volcano.
