UNITAR-UNOSAT analysis used a TerraSAR-X image acquired on 24 May 2021, at 16:13 UTC, to observe the lava flow. Within the analysis extent, about 1,600 structures are potentially affected by the lava flow.This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR-UNOSAT.Important Note: Lava flow analysis from radar images may overestimate the presence of the lava tract due to the backscattering properties of the radar signal. https://unitar.org/unosat/node/44/3289 https://www.gdacs.org/contentdata/maps/unosat/VO/1000023/UNOSAT_A3_Natural_Portrait_VO20210523COD_DamageAssessment_MountNyiragongo_DRCongo.jpg guid_2 Tue, 25 May 2021 14:15:26 Cette carte illustre les structures et bâtiments potentiellement impactées par la coulée de lave dans le district de Nyiragongo, province du Nord-Kivu en République Démocratique du Congo suite à l'éruption du volcan Nyiragongo du 22 mai 2021. A partir de l'analyse d'une image radar TerraSAR-X acquise le 24 mai 2021 à 16:13 UTC, UNITAR-UNOSAT a observé une coulée de lave qui s'est arrêtée à 700m des installations aéroportuaires. Sur l'étendue de l'analyse, environ 1,600 structures sont potentiellement impactées par la coulée de lave à la date d'acquisition de l'image radar.Ceci est une analyse préliminaire et n'a pas encore été validée sur le terrain. Veuillez d'envoyer vos commentaires à UNITAR-UNOSAT.Note: L'analyse de coulée de lave à partir d'une image radar peut surestimer la trace de la coulée de lave à cause du coefficient de rétrodiffusion du signal radar. https://unitar.org/unosat/node/44/3290 https://www.gdacs.org/contentdata/maps/unosat/VO/1000023/UNOSAT_A3_Natural_Portrait_VO20210523COD_DamageAssessment_MountNyiragongo_DRCongo_FR.jpg guid_3 Tue, 25 May 2021 15:51:54 This map illustrates potentially affected structures and buildings in Nyiragongo district, Nord-Kivu province, DR Congo as detected by satellite image acquired after the 22 May 2021 Nyiragongo volcanic eruption.

UNITAR-UNOSAT analysis used a Sentinel-1 image acquired on 25 May 2021, at 16:21 UTC, to extract the lava flow extent. Within this map extent, 1,540 structures and 9 km of roads appear to be affected by the lava. This is a preliminary analysis and has not yet been validated in the field.
