Abstract
Semeru volcano is one of the most active volcanoes in Indonesia. It has been continuously active in the last
several years. In early December 2021, the Semeru volcano erupted and ejected materials into the surrounding area. Such
volcanic activities may lead to surface deformation in the volcanic edifice. This study investigates the Semeru volcano
surface deformation from August 2020 to March 2022. InSAR observations from Sentinel-1 were used in the analysis. The
time series displacement shows changes in the surface topography during the observation period. In the summit area, we
observe about ~2-3 cm/year inflation rate. However, a southeastern slope from the summit seems to be deflated about ~ 6
cm/yr. From the time series of displacement, we suggest the inflation/deflation period occurred before December 2021
eruption.
