Philibosian and Simon (2011) and Chaussard and Amelung (2012) identified a deformation event at Lamongan volcano that is likely linked to a magmatic intrusion at several kilometres’ depth. Both authors identified a central line-of-sight change of ~12cm between September and December 2007. The subsequent acquisitions suggest that the area was stable following the magma intrusion event. However, Philibosian and Simon (2011) highlighted the deformation event is poorly constrained due to only having two prior acquisitions before the uplift.
