“…Very small variations in initial plume position with respect to the cratonic bodies (up to several tens of km only) appear to be able to change the relation between these three segments of separated plume head, which, in turn, alters the degree of development of the corresponding rift branches. We argue, thus, that the resulting rifting pattern is largely controlled by the relative position of the initial mantle plume anomaly with respect to first-order lithospheric thickness differences rather than by secondorder crustal and/or lithospheric compositional heterogeneities as commonly assumed (Corti et al, 2007;Katumwehe et al, 2015;Smets et al, 2016;Theunissen et al, 1996).…”

“…It is commonly assumed that the Cenozoic rifts have avoided the cratons and follow the mobile belts (McConnell, ; Mohr, ), which serve as the weakest pathways for rift propagation. Structural control exerted by the pre‐existing heterogeneities within the Proterozoic belts at the scale of individual faults or rifts has also been demonstrated (Corti, van Wijk, Cloetingh, & Morley, ; Katumwehe, Abdelsalam, & Atekwana, ; Morley, ; Ring, ; Smets et al., ; Theunissen, Klerkx, Melnikov, & Mruma, ; Versfelt & Rosendahl, ).…”

“…All of the stations located on volcanic strata in the VVP have null measurements and high standard deviations of ϕ, similar to those in the RVP sector. The NW and N‐S ϕ patterns parallel the two magmatic trends: active dike intrusion from reservoirs beneath Nyiragongo strike approximately N‐S (Wauthier et al, ), whereas the aligned chain of volcanoes, faults, and fissures west of the Kivu rift strike NW (Smets et al, ; Wood et al, ).…”

“…Another natural potential factor that could affect the displacement rates of active landslides is seismicity (e.g., [66][67][68][69][70]). The city of Bukavu is commonly affected by earthquakes [41,42,71,72] and the Mw 5.8 August 2015 earthquake with the epicentre located~40 km north of the centre of Bukavu ([52]- Figure 1) could have potentially affected the slope stability over the city [70,[73][74][75]. The displacement time series in Figure 7, however, show no change (anticipated it could be acceleration) in the deformation rates after this event.…”
