[ABSTRACT]Since 2010, Mount Bromo has erupted at least two times with high intensity has recorded. Regarding to CVGHM reported, Mount Bromo activity increased on 1 November 2015 and started erupting with lava on Tuesday morning, 26 January 2016. Based on the eruption evidences Mount Bromo is Strombolian Volcano, relatively mildly explosive at discrete but fairly regular intervals of seconds to minutes. Recently, remote sensing has played as an important role to observe volcano behaviour. We investigated ground deformation by interferometric SAR method related to ground structure before and after eruption. We expect the Time Series-InSAR deformation field to infer volume changes, geometries and locations of sources of deformation involved in the future eruption. Ground displacement in the radar line-of-sight (LOS) direction is obtained from the phase difference of synthetic aperture radar (SAR) pairs of the same area acquired at different times (interferograms) then be flattened by removing the topographic phase an inflating volcano (or any other landform) produces a pattern of concentric fringes in a radar interferogram from which the effects of viewing geometry and topography have been removed. InSAR studied in Mount Bromo has observed by e.g. Arliandy and Wataru (2016) the results are shown the displacement changes around Mount Bromo area up to 26 Cm, where is the higher shifted in 2015 eruption. The results are allowed us to understand evidences of disaster in the field and could implemented to urban plan engineering in particular civil engineering work and mitigation assessment to reduce number of damages and fatalities.
