AB  - The eruptions of the Nyiragongo volcano documented respectively on January 10, 1977, January 10, 2002 and May 21, 2021 were all fissural on its flanks characterized by the opening of the invoices followed by the effusion of very fluid lava flows.

They are divided into three categories including the emissive fractures of the newly formed flows, the old fractures reopened or reactivated by the new eruption which are in certain places emissive and those formed by the seismicity comes after the eruption of volcano. Emissive fractures are very wide and deep, fractures and cracks resulting from seismic activity are narrow and non-emissive.
The old fractures (formed by the eruptions before 1977) were mapped by Thonnard, those of 2002 by Jean Christophe Komorowky of IPGP France and the Deformation service currently Department of Geodesy and the map of new fractures which has been updated by the team of the Department of Geodesy of volcanological observatory of goma.
These open fractures further north on the flank of the volcano enter a volcanic cone through a single wide and deep opening exiting it on the other side through a network of parallel fractures, which emit lava and are in some places covered by lava flows that come upstream.
The post-eruptive activity of the 2021 eruption, like the other two previous ones, was accompanied by strong seismicity, the epicentres of which were located in the east of the city of Goma and the western part of the city of Gisenyi (Rwanda) then in Lake Kivu. The fractures opened during this activity are oriented North-South like most of the others open to the North on the southern flank of Nyiragongo but have many branches, especially at the epicentres of the earthquakes.

Abstract

The eruptions of the Nyiragongo volcano documented respectively on January 10, 1977, January 10, 2002 and May 21, 2021 were all fissural on its flanks characterized by the opening of the invoices followed by the effusion of very fluid lava flows. hese fractures are more important on its southern flank. They are divided into three categories including the emissive fractures of the newly formed flows, the old fractures reopened or reactivated by the new eruption which are in certain places emissive and those formed by the seismicity comes after the eruption of volcano. Emissive fractures are very wide and deep, fractures and cracks resulting from seismic activity are narrow and non-emissive. The old fractures (formed by the eruptions before 1977) were mapped by Thonnard, those of 2002 by Jean Christophe Komorowky of IPGP France and the Deformation service currently Department of Geodesy and the map of new fractures which has been updated by the team of the Department of Geodesy of volcanological observatory of goma. These open fractures further north on the flank of the volcano enter a volcanic cone through a single wide and deep opening exiting it on the other side through a network of parallel fractures, which emit lava and are in some places covered by lava flows that come upstream. The post-eruptive activity of the 2021 eruption, like the other two previous ones, was accompanied by strong seismicity, the epicentres of which were located in the east of the city of Goma and the western part of the city of Gisenyi (Rwanda) then in Lake Kivu. The fractures opened during this activity are oriented North-South like most of the others open to the North on the southern flank of Nyiragongo but have many branches, especially at the epicentres of the earthquakes.

Abstract: (french)

Les éruptions du volcan Nyiragongo documentées respectivement du 10 Janvier 1977, du 10 Janvier 2002 et du 21 mai 2021 ont été toutes fissurales sur ses flancs caractérisés par l’ouverture des factures suivie de l’épanchement des coulées de laves très fluides. Ces fractures sont plus importantes sur son flanc Sud. Elles sont réparties en trois catégories dont les fractures émissives des coulées nouvellement formées, les fractures anciennes réouvertes ou réactivées par la nouvelle éruption qui sont en certains endroits émissives et celles formées par la séismicité vient après l’éruption de ce volcan. Les fractures émissives sont très larges et profondes, les fractures et fissures issues de l’activité séismiques sont étroites et non émissives. Les anciennes fractures (formées par les éruptions d’avant 1977) ont été cartographiées par Thonnard, celles de 2002 par Jean Christophe Komorowky de l’IPGP France et le service de Déformation actuellement département de Géodésie et la carte des nouvelles fractures qui a été actualisée par l’équipe du Département de Géodésie. Ces fractures ouvertes plus au Nord sur le flanc du volcan entrent dans un cône volcanique par une seule ouverture large et profonde y sortent de l’autre côté par un réseau de fractures parallèles, qui émettent de la lave et sont à certains endroits recouvertes par des coulées de lave qui viennent en amont. L’activité post éruptive de l’éruption de 2021 comme les deux autres précédentes était accompagnée par une forte séismicité dont les épicentres étaient localisés dans l’Est de la ville de Goma et la partie Ouest de la ville de Gisenyi (Rwanda) puis dans le lac Kivu. Les fractures ouvertes lors de cette activité sont orientées Nord-Sud comme la plupart des autres ouvertes au Nord sur le flanc Sud du Nyiragongo mais ont beaucoup de branches surtout aux épicentres des séisme.
