Summary of main findings: A total of 2,275 destroyed and 125 severely
damaged buildings were identified within the town of Baga (Borno
State, Nigeria) based on
a change detection analysis of two very high
resolution satellite images collected on the mornings of April 6, before
the violence, and April 26, 2013, after the violence. Damages were
widely distributed across the southern half of Baga, with multiple
clusters of near total building destruction measuring approximately 8
hectares in total area.
Virtually all identified building damages exhibit
signatures fully consistent with fire, including the presence of burn
scars, destroyed trees as well as intact load-bearing walls without a
roof. Further, damages match the spatial extent of satellite-detected
active fire zones recorded on the night of April 16 (20:55 UTC, 21:55
local time) and the afternoon of April 17, 2013 (12:15 UTC, 13:15 local
time) strongly suggesting identified building damages occurred during
this period. It is likely that a small percentage of destroyed or severely
damaged buildings have not been identified because of tree cover.
Total building damages are therefore likely to be higher.
