Downstream impacts of the Salkantay rock avalanche and debris flow<\/h4>\n

On 8 March 2020 Planet Labs<\/a> captured an image showing the downstream impacts of the Salkantay rock avalanche and debris flow<\/a>.\u00a0 Cloud-free days are rare in this part of the world are rare, so this is a good catch.\u00a0 Unfortunately the area of the actual failure is just off the edge of the image, but the downstream effects of the debris flow are clear.<\/p>\n

This is an image of the area captured before the landslide on 7 January 2020 with the Planet Labs<\/a> Planetscope system:<\/p>\n

This is an image collected with the same system on 8 March 2020 showing the aftermath of the debris flow:-<\/p>\n

The impact of the landslide is clear.\u00a0 On the east side of the image a small proportion of what is presumably the landslide deposit can be see, before the channelisation occurred.\u00a0 The debris flow has eroded the channel flowing initially towards the west, and then towards the north. In some places erosion of the banks appears to have triggered failures on the hillsides.\u00a0 In this example, a new landslide has been triggered, and an existing one has been reactivated.\u00a0 In the latter case, a road across the landslide appears to have been destroyed:-<\/p>\n

Hopefully images will be captured in the next few days showing the failure itself, although this is of course dependent on cloud cover.<\/p>\n
