Sentinel-2A captures a giant ice avalanche in Tibet

The Nature News website reported yesterday on a massive ice avalanche that happened in Rutog, Tibet, on 17 July 2016. This ice avalanche killed 9 people and may be one the largest ever observed. The ice and rock mixture spread over 6 km from the collapse point up to the Aru Co lake shoreline.

Sentinel-2A image of the Rutog ice avalanche acquired on 21-Jul-2016 (4 days after the event). Click on the image to see at full resolution (1 pixel = 10m).

Nothing escapes from Sentinels! I used the Sentinel-2A image above to digitalize the avalanche extent and found that the avalanche covered a total area of 8.8 km², close to the value that was indicated in several news websites (10 km²).

A closer view of the avalanche site is available here: http://english.cri.cn/12394/2016/07/20/3441s934928.htm

[edit] The second episode about this avalanche is here.

The missing link to valorize CESBIO’s applicative research works

=>  My colleagues at CESBIO are extremely creative! Over the past ten years, they have developed a wide range of new products and methods for extracting information from Copernicus data. They don’t just develop and validate the method on a few sites; they continue their work until they have produced data for the whole of […]

Le chaînon manquant dans la valorisation des travaux de recherche en télédétection

=> Mes collègues du CESBIO sont très créatifs ! Ils ont mis au point, au cours des dix dernières années, un grand nombre de nouveaux produits et de méthodes d’extraction de l’information à partir des données Copernicus (Sentinel-1 et 2). Et bien souvent, ils ne s’arrêtent pas à la mise au point de la méthode […]

Sentinel-2 overtakes Landsat in scientific litterature

OpenAlex is a new, yet already very useful, open database for exploring scientific literature. For an upcoming blog post on the CNES Datacampus website, I analysed the proportion of papers that used only one of the Sentinel-2 or Landsat missions, as well as those that used both, in 2025. What struck me was that Sentinel-2 […]
