Deformation during 2006 May 29 - 2007 Mar 05 [Uplift; Observed by InSAR]

Start Date: 2006 May 29 Stop Date: 2007 Mar 05 Direction: Uplift Method: InSAR
Magnitude: 21.000 cm Spatial Extent: Unknown Latitude: Unknown Longitude: Unknown

Remarks: An inflation episode at Paka volcano results in 21 cm of uplift.

Figure (see Caption)

Inflation episode at Paka, 2006?2007. A: Stack of interferograms spanning the entire event showing the total 21 cm of uplift. B: Interferograms covering short timer periods showing precursor uplift and subsidence at a second source located ~4 km south of the main event. Uplift of the main source occurred in two consecutive interferograms. Source locations are marked by white circles; red (+)?uplift; blue (?)?subsidence. C: Best-fitting source models. Two candidate source geometries are used for each event: a Mogi (point source), or horizontal penny-shaped crack. In all cases, the penny- shaped crack model provides a better fit to data, both qualitatively and quantitatively. Each color cycle (fringe) represents 2.8 cm of displacement in the satellite line of sight. rms?root mean square residual betweeen model and data. Each subplot has the same extent.
