The disaster at Yanawayin Lake was attributed to excessive rainfall which caused a significant landslide. This event took place in a mining area known for its rich mineral resources, where numerous workers were present, either as laborers or support staff. The mountainous topography combined with the saturated soil created a precarious situation, and the landslide unleashed a torrent of mud and debris into the lake, generating massive waves. These waves surged into the nearby Chungar mining camp, where many workers lived and worked, leading to a tragic loss of life. Remarkably, emergency response efforts began swiftly after the landslide, but the devastation was overwhelming.

In the aftermath, the Peruvian government and local authorities faced scrutiny regarding mining regulations and the safety measures in place at such vulnerable sites. The incident prompted discussions on the need for better disaster preparedness and infrastructure improvements to safeguard against similar occurrences in the future. Communities affected began rallying for more stringent regulations around mining operations to ensure safety and protect workers from environmental hazards that could arise from their workplace.

This event remains a significant chapter in the narrative of Peru's mining history, illuminating the risks faced by those who work in extractive industries, especially in geographically unstable regions. It raised awareness about the impact of weather patterns, environmental management, and the responsibility of mining companies to ensure the safety of their personnel. Furthermore, the tragedy drew attention to the need for comprehensive disaster management systems to avert further loss of life in the advent of natural disasters.
