Deformation during 2009 Jan 14 - 2010 Jul 28 [Subsidence; Observed by InSAR]

Start Date: 2009 Jan 14 Stop Date: 2010 Jul 28 Direction: Subsidence Method: InSAR
Magnitude: 4.000 cm Spatial Extent: Unknown Latitude: Unknown Longitude: Unknown

Remarks: Alternating pulses of uplift and subsidence may suggest interaction between the magmatic and hydrothermal systems at Alutu.
