Planet Labs images of landslides triggered by the 2019 Cotabato earthquakes in the Philippines
Planet Labs satellite images have now become available showing at least some of the landslides triggered by the 2019 Cotabato earthquakes sequence in the Philippines, which I highlighted last week. Cloud is still affecting some of the area, so the picture is not yet fully clear, but there is sufficient detail to see at least two large clusters of landslides. Below is an overview image, based on an image collected on 8 November 2019, of one of the clusters (located at 6.960, 125.200). I’ll call this group of landslides the Barangay Buhay cluster; the other cluster I have found is at Barangay Bato (located at 6.84, 125.16). I will endeavour to feature the other later this week.
There are two features of note here. One is the c. 1 km long landslide at Barangay Buhay in Makilala, North Cotabato, which is shown in a photograph in an article about survivors of the earthquake, published in Minda News. The article details the survival of an agricultural worker, who was buried up to his neck by one of the landslides, but I think this was probably at Barangay Bato.
To the east is a large cluster of landslides, the extent of which is not fully covered by the imagery. This cluster, which extends for at least 5 km from east to west and 3 km from north to south, contains a large number of landslides triggered by the Cotabato earthquakes.:-
The Barangay Bato cluster of landslides, triggered by the Cotabato earthquakes, is also large, so watch this space…
