Extended Data Fig. 10: Urban development at Funu landslide.

a, Very-high resolution shaded relief of the landslide from UAS-SfM (Oct. 2017). The resolution stresses the very-high density of individual building (the population is estimated to ~55 000 inhab./km²4). b, Funu landslide fastest unit, where characteristic landslide features (such as surface discontinuities, tension cracks, marked steps in slope profile) translating important internal deformation are the most visible. Two gullies (also shown in c,) delimit a sub-unit where velocities are the highest (up to 3 m/yr). d, Historical picture showing part of Funu landslide in 1959. It highlights the low housing density at that time. e, Illustrates work on the drainage systems in Bukavu (photo taken in 1959). © Royal Museum for Central Africa.
