Cyclone Yaku was a large-scale weather phenomenon that affected the northern provinces of Peru. Torrential rains and mudslides were widespread in the regions of Tumbes, Piura, and Lambayeque. Lima, the capital of Peru, was not spared this natural disaster. Human settlements in the northern cone, such as the districts of Puente Piedra and Carabayllo, as well as the province of Canta, were devastated by massive mudslides, which left thousands homeless, injured, and dead in their wake. The inhabitants of these areas never imagined such a weather phenomenon would occur; it seemed almost impossible. Nature was cruel to them. Cyclone Yaku caused damage to infrastructure and loss of life. As a consequence of the rains, price increases were observed, and cases of dengue fever surged in Peru, triggering an epidemic. Cyclone Yaku was a large-scale natural disaster and an enemy that affected all aspects of Peruvian society.
