The Las Tejer\u00edas landslide disaster: Planet Labs imagery of the source of the flows<\/h4>\n

The cloud has now cleared sufficiently that Planet Labs<\/a> has been able to capture an image of the source area of the 8-9 October 2022 Las Tejer\u00edas landslide disaster in Venezuela<\/a>.\u00a0 The image below was captured by one of the PlanetScope instruments on 22 October 2022:-<\/p>\n

The main channel, which flows towards the south to the site of the town, cuts across the image from the west to the south.\u00a0 To the north of the channel there is evidence of many shallow landslides, most of which feed into tributaries of the main channel.\u00a0 In the main drainage line the evidence of high flows can be seen in the form of sediment and\/or bedrock exposed or deposited on the channel floor.<\/p>\n

For reference, the image below shows the same location on 23 September 2022, before the disaster:-<\/p>\n

In the juxtapose below I have tried to compare the two images:-<\/p>\n

The juxtapose images highlight clearly the role of the multiple shallow landslides that have become channelised mudflows \/ debris flows to cause the destruction in the town.\u00a0 These types of landslides are characteristic of extreme rainfall events.<\/p>\n

Meanwhile, heavy rainfall continues to cause extensive damage in Venezuela<\/a>, with another period of rainfall occurring yesterday<\/a>.\u00a0 This video shows flooding in Monta\u00f1a Alta:-<\/p>\n
