Yanawayin (Quechua yana black, Ancash Quechua wayi house, "black house",[1][2] -n a suffix, other spellings Yanahuain, Yanahuin, Yanahuni, Yanahuani) is a lake in the central Peruvian Andes. It lies in the Lima Region, Huaral Province, Andamarca District, near the village of Yanawayin (Yanahuain).[3][4] The lake is situated at an altitude of about 4,900 metres (16,100 ft).


The site made world headlines in 1971 when on March 18 a rock avalanche of 100,000 cubic metres (3,500,000 cu ft)[5] fell from an outcrop of jointed limestone about 400 metres (1,300 ft) above the lake. It created a wave of 30 metres (98 ft) that destroyed the Chungar Mining Company (Cia Minera Chungar, S.A.) camp on the shore, destroyed all the mines' surface facilities,[5] and killed 200–600 miners.[3][5][6]
