Extended Data Fig. 3: Urban density and landslide impacts.
From: Acceleration of a large deep-seated tropical landslide due to urbanization feedbacks
a, Very-high resolution UAS-SfM orthomosaic (Oct. 2018) of a section the landslide that includes the 14-ha ‘fastest unit’ (in red). Note the very-high density of individual building (the landslide population is estimated to ~55 000 inhab./km²4). In blue is highlighted the extent of the two gullies that partially delimit the toe of the fastest unit. b, View of the landslide taken from the headscarp. Lake Kivu is visible in the background. c, and d, damages to a road at the border of the fastest unit, where velocity gradients are the highest. e, damages to a house within the landslide. Extent of a, is shown in Extended Data Fig. 4.
