A. Situation Analysis
A.1 Description of the disaster
On 23 March 2015, flash floods and landslides, which are recurring events in the country, affected the central highlands in Peru. Due to the geomorphology of the area, landslides occurred and affected several homes. The following creeks experienced raised water levels and flooded surrounding areas: Pedregal, Carossio, Rayos del Sol, Quirio, San Antonio, California, La Trinchera, Buenos Aires, La Cantuta, Moyopampa, La Libertad and Mariscal Castilla. The Lurigancho-Chosica district in Lima province was the first area to be severely affected from this flooding.
At about 17:30 hours that same day, heavy storms activated the Cashahuacra,
Tres Cruces, Las Monjas, Cuculi, Rayos del Chingolay, Acopaya and Pomaticla creeks in the Santa Eulalia district, as well as the 9 de Octubre and Cupiche creeks in the Ricardo Palma district and the Buenos Aires creek in the Santa Cruz de Cocachacra district, causing landslides that affected homes and roads in the Huarochirí province, primarily in the Santa Eulalia district. On 25 March, the national government declared a 45-day state of emergency in the Lurigancho-Chosica district in Lima province.
This event caused damage to lives, health, housing and roads. The lower levels of dwellings in Carossio, Rayos del Sol, Buenos Aires and Moyopampa, the areas most affected by the landslide, were completely covered with mud, and public transport vehicles were trapped in material dragged by the landslide.
According to reports, 9 people were killed, 55 were injured, and 4,700 suffered damages to their homes in Chosica and Santa Eulalia. A total of 207 dwellings collapsed; 154 were rendered uninhabitable; and 51 suffered damages.
