Preliminary estimates suggest the landslide on the flanks of Mount La Perouse involved 68 million metric tons (75 million short tons) of material, which would make it the largest known landslide on Earth since 2010. The Operational Land Imager on Landsat 8 acquired this image on February 23, 2014. The avalanche debris appears light brown compared to the snow-covered surroundings. The sediment slid in a southeasterly direction, stretching across 7.4 kilometers (4.6 miles) and mixing with ice and snow in the process. The slide was triggered by the collapse of a near-vertical mountain face at an elevation of 2,800 meters (9,200 feet), according to Columbi
