Damage assessment of the August 2020 Beirut explosion using Sentinel1's interferometric SAR processing

Abstract

For the Beirut explosion site in August 2020, we investigated whether damage could be identified from Sentinel1 data. We selected data from February 20 and June 7, 2020 as pre-explosion data, and data from August 6 as post-explosion data, and conducted interferometric SAR processing. We checked VH, VV and the phase changes values for the explosion site, areas heavily affected by the explosion, and areas almost unaffected by the explosion, and it was found that the VH and VV values for the explosion site showed clearer changes, while the phase changes value for the collapse of surrounding buildings were larger.
