In Turkey, the Disaster and Emergency Management Presidency (AFAD), affiliated to the Ministry of Interior, has completed the installation of 300 thousand tents in the provinces affected by the earthquakes. On Feb 16, Pléiades captured such installation on the parking of the New Hatay Stadium near Antakya. I count about 400 tents in this picture. […]
Because the first images were partly cloudy, the Pléiades 1A and 1B satellites (CNES/Airbus) continued to acquire images over Kyrgyzstan and a cloud-free 0.7-m stereoscopic pair was acquired 16 July 2022. We could also obtain a 1.5 m SPOT7 stereoscopic pair from the Airbus DS archive thanks to the Dinamis initiative. The latter was taken […]
Last week, Simon Gascoin and I spent quite some time working on the Marmolada event. Just a week-end to rest and Twitter reminded us Monday morning that this summer 2022 was special for glaciers. Not only are they out of balance with the climate and will probably suffer one of their most negative mass balance […]
The deadly Marmolada glacier collapse happened on 3 July 2022. On 6 July 2022, Pléiades 1B (CNES, Airbus DS) acquired a clear-sky stereo pair of the area. From these images we could estimate a detached volume of ice of 65’000 ± 10’000 cubic meters. First, we generated a digital elevation model (DEM) from Pléiades stereo […]
Last year, in this post, I showed the comparison of two Sentinel-2 images of Saint Barthélemy in the Caribbean before and after the powerful Hurricane Irma. A new feature in the EO Browser enables to plot the evolution of the mean NDVI within a polygon. I drew a rough polygon of Saint Barthélemy to check […]
In this post « Landslides in Kyrgyzstan captured by Sentinel-2 » I showed two landslides that I identified as the Kurbu and Ayu landslides, both featured in the AGU landslide blog. However, as pointed out by Isakbek Torgoev, the Kurbu-Tash landslide is located about 5 km farther south than the one I found on the Sentinel-2 image […]
The giant Kurbu-Tash landslide in Kyrgyzstan occurred on 23-24 April 2017 and was highlighted by Dave Petley in the landslide blog of the American Geophysical Union.
