Planet satellite image of the urban landslides in the Alto da Serra area of Petr\u00f3polis, Brazil<\/h4>\n

Planet have very kindly captured a new high resolution satellite image of the 15 February 2022 landslides in Petr\u00f3polis in Brazil<\/a>.\u00a0 These are 50 cm resolution images, providing very high level of detail.\u00a0 The first of the two images was taken in the area of Alto da Serra – the centre of the image is at about -21.516, -43.169:-<\/p>\n

In the centre of the image are multiple shallow landslides, starting on the hillsides but descending into the inhabited areas.\u00a0 There are also several landslides on the western side of the image.\u00a0 The landslides in the centre of the image are worth examining in more detail:-<\/p>\n

In most cases these are smallish, shallow slips that have entrained debris along the track to form channelised flows.\u00a0 The long landslide in the lower eastern corner is interesting – it appears to have damaged buildings and to have deposited debris on the road.<\/p>\n

Planet has also captured an image to the south of the above image, close to Morro da Oficina<\/a>:-<\/p>\n

The lower portion of the large landslide at Morro da Oficina is just visible in the northeast corner of the image.\u00a0 But note the multiple landslides in the centre of the image and towards the upper part.\u00a0 Again, these slides have started in unpopulated areas but the debris has flowed into the inhabited regions.\u00a0 As the image below shows, there is evidence of serious structural damage in places:-<\/p>\n

These multiple landslides are extremely hazardous for the local population and are difficult to manage in an emergency situation.<\/p>\n

The latest news from the city makes grim reading.\u00a0 There are now 117 confirmed deaths, with a further 140 reported to be missing<\/a>.\u00a0 Some reports indicate that the number missing may be as high as 700 people<\/a>, although it is not unusual for the number missing to be far too high at this stage of an emergency.\u00a0 It is not clear how many of these died in the landslide at Morro da Oficina, but the toll there is undoubtedly substantial given that 80 houses were destroyed.\u00a0 So far, 269 landslides have been identified, and a further 56 “landslides and falls of trees” have been recorded<\/a>.<\/p>\n
