The 2017 Queensland floods

The Google Earth Blog spotted the recent Queensland floods in Sentinel-2 imagery.

The Sentinels provide systematic coverage of the land areas, which facilitates the detection of changes due to natural hazards. Hence we can compare this Sentinel-2A image with another one that was captured last year during the same season to better highlight the extent of the flooded areas.

As always, it has been a long journey from the idea, at the beginning of the century, to the selection in 2013 as the seventh Earth Explorer Mission by ESA, to the […]

Sentinel-2 reveals the surface deformation after the 2025 Myanmar earthquake

Sentinel-2 captured several clear-sky images of Myanmar before and after the 28 March 2025 earthquake. The animation below shows a 5-day apart sequence of images captured by Sentinel-2B and Sentinel-2C (10 m resolution) near the epicenter located close to Mandalay. The surface slip due to the earthquake follows the Sagaing Fault, a major fault in […]

Evolution de l’altitude de la ligne de neige au cours des 41 dernières années dans le bassin versant du Vénéon (Oisans)

Pour contribuer à caractériser les conditions hydrométéorologiques lors de la crue torrentielle qui a frappé la Bérarde en juin, j’ai analysé une nouvelle série de cartes d’enneigement qui couvre la période 1984-2024 [1]. Grâce à la profondeur temporelle de cette série, on constate que l’altitude de la ligne de neige dans le bassin versant du […]
