While neither study was focused on this volcano, Slamet was included in both the 2006-2009 ALOS study of West Sunda, and the 2007-2008 PALSAR interferometric study of the island of Java performed by Chaussard & Amelung and Philibosian & Simons, respectively.
Both surveys noted significant deformation at the volcano during the study periods; over the three years of observation, Chaussard & Amelung recorded a total uplift of 12.2cm at the volcanic edifice, at the relatively constant rate of 6.8cm/yr. However, the rate of deformation tapered significantly between early-mid June 2009, during which time Slamet experienced a series of small explosive eruptions.
Philibosian & Simons’ results corroborate these observations, though their measurement of net uplift at the volcano is slightly smaller than that of Chaussard & Amelung – approximately 5cm of displacement over the two year period (2007-2008), at a greatly reduced rate of 3cm/yr.
Both studies agree that the deformation at Slamet was magmatic in origin, and almost certainly linked to the 2009 eruptions. Philibosian & Simons estimate that their observed deformation signals are most accurately modelled by an injection of magma into a shallow source of approximately 1.5km depth, amounting to a volume increase of 5 × 105 m3.
