Observations of Deformation
|Duration of observation:||January 2003 to September 2010, 1992- 1999 (ref2)|
|Inferred cause(s) of deformation:||Magmatic|
|Characteristics of deformation:|
At least two sources are considered to represent permanent zones of magma storage given their persistent or recurrent activity. Elastic deformation models indicate the presence of a flat-topped magma reservoir at ∼1.1 km below sea level and an oblate-spheroid cavity at ∼4.9 km b.s.l. The two reservoirs are hydraulically connected. Ref 1.
