Image of a landslide in Uganda
According the thinkhazard, Namibia has a low chance of landslides. Honestly, when you look up Namibia and landslides, you mainly get political news. Mass wasting events in Namibia is so infrequent, that it was difficult to find information about it. However, it is clear that landslides is an issue in Africa in general. There are places in Africa that are currently being inundated with rain, and the land cannot handle the water and it is causing landslides. Uganda suffered from a landslide just last month for example.
