On Sunday March 4th 2012, an ammunition depot exploded in the capital of the Republic of Congo, Brazzaville. The explosion affected an estimated 125,000 people and caused significant human losses and physical damage, leading to a high level of internal displacement.
In the aftermath of the disaster, REACH teams were deployed to Brazzaville in March 2012 to carry out a rapid assessments on displacement (with for example, this map illustrating the number of people hosted by neighbourhood as of April 2012) and damage (with for example this map from April 2012 illustrating the difficult access to water after the explosion), collecting information through field interviews and by analysing images derived from remote sensing. Indeed, the use of remote sensing enabled assessment of areas that were not accessible by the field teams.
Deployment ended in April 2012.
