Images of the landslide site show where a large parts of mountainside had collapsed, destroying everything in its path. A local commentator suggested that rivers and creeks have been blocked by mining waste, and mountainside eroded by bush fires and drought.

Roads have been blocked by flooding and landslides, and several other communities remain isolated. Telecommunications, power and drinking water supplies have also been severely affected. The French Red Cross installed a water purification unit and drinking water and other essential relief supplies have been distributed to the affected areas.

“A depression, south of the Solomon Islands, widened and slowly headed south on Saturday 19 November, while at the same time a mass of warm tropical air of tropical descended in the region. These conditions generated torrential rains on the east of New Caledonia, accompanied by thunderstorms and gusts of wind, especially in the Houaïlou / Kouaoua areas.”
