As many as 92,000 people were displaced when more than 25,000 homes collapsed or were left uninhabitable between late November 2016 and mid-March after persistent rainfall and flooding. In early 2017, the most damage was recorded in Ancash, Cajamarca, Huancavelica, Ica, Lambayeque, La Libertad, Lima, Loreto, Piura and Tumbes provinces, which declared states of emergency (PAHO, 22 March 2017). Since the end of January, a coastal El Niño pattern with an abrupt rise in sea surface temperature has brought heavy rains, storms, floods and strong winds (UNICEF, 21 March 2017).
