Planet Labs imagery of the Pasir Panjang landslide in Indonesia<\/h4>\n

Planet Labs have now managed to capture good quality satellite imagery of the Pasir Panjang landslide<\/a> in Brebes, Indonesia, which killed 18 people last week<\/a>.\u00a0 Drone footage had indicated that the landslide had a channelised component, but the source was unclear.\u00a0 This Planet Labs image<\/a> was captured at 02:29 UTC on 27th February.\u00a0 It includes the entirety of the landslide:<\/p>\n

The source of the landslide appear to be quite a large slide – the length is about 200 m and the width about 100 m.\u00a0 There is a long channelised component – well over 1 km – before the landslide emerged into open topography and spread across the fields.\u00a0 There is perhaps a hint of bedrock in the north west corner of the source area, perhaps suggesting a dipslope failure or one that has occurred on the bedrock regolith interface.<\/p>\n

For comparison, this is a Planet Labs image of the same area before the landslide:-<\/p>\n

These images serve to illustrate how difficult it is to determine the likely impact of landslides in upland, forested areas.\u00a0 Note that in this case the landslide was not associated with deforestation or a change in land use, as was noted by the local authorities.\u00a0 Landslides are the dominant erosive process in this type of landscape, and they occur naturally.\u00a0 In this case the town was located away from the path of the flow, which reduced the losses.\u00a0 The images suggest that there are other communities that are located in the path of potential flows down other gullies.<\/p>\n
