Kanyanza This map illustrates the lava flow extent and the related geological information north of GomaBulenggia airport, Nord-Kivu province, D.R. of the Congo as detected by satellite images acquired after the eruption of 1°36'S the on 22 May 1°36'S 2021. UNITAR-UNOSAT analysis used Sentinel-2 and SAOCOM-1A images acquired on 27 May 2021, at M 4.7 respectively 08:30 UTC and 02:21 UTC, to extract the lava flow extent. Within this map, three vents have been identified along the hillside south of Nyiragongo caldera. In addition about 10 km of fissures have been mapped and are mainly in NNE-SSW and NNW-SSE directions.

This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR-UNOSAT. 1°38'S 1°38'S Legend
