|Duration of observation:||2006|
|Inferred cause of deformation:|
|Characteristics of deformation:|
No deformation was detected at the Quill during an 2006-2008 ALOS survey of Latin America, however due to limited data, interferograms could only be made spanning 3 months in 2006 (Fournier et al., 2010).
