UNITAR- UNOSAT analysis used a TerraSAR- 1°35'S X image acquired on 24 May 2021, 1°35'S ≈ 4,000 at 16:13 UTC, to observe the lava Kanyanza flow. Within the analysis extent, about 1,600 structures are potentially affected by the lava flow. This is a preliminary analysis and 10 has not yet been validated in the k m field.
