Lascar

Volcano number: 355100
Region: South America
Country: Chile
Geodetic measurements? Yes
Deformation observation? Yes
Measurement method(s): InSAR
Duration of observation: 1992-2000
Inferred cause 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.
