Recent landslides in Mbonjo, located between 3°55’’–4°13’’N and 9°12’’–9°23’’E in
the coastal town of Limbe were mapped using an unmanned aerial vehicle, field mapping
and remote sensing techniques and documented in this paper. This town is susceptible to
natural hazards and in July 2018 and 2020, a swarm of landslides occurred in Mbonjo
towards the outskirt of Limbe, killing five people and injuring 10 others, obstructing the
road and destroying important properties. These landslides were studied for a better un-
derstanding and the occurrence of such natural phenomena and human threat diminution.
From the field studies, the slides were small to medium scale, characterized by low slope
gradients (15-250), short depletion zones (20-25m) and length (~31.1m). These slides cov-
ered an area of 603.5-2000.75m2 and the volume of ground debris were bracketed between
626.81 and 8757.60m3. Slope steepness and human activities such as excavation of the
slopes were the main conditioning factors, whereas intense rainfall was the main trigger
of Mbonjo landslides. It is urgent to take concrete measures to tackle this serious threat to
human life in the study area.
