Tibet Earthquake: Mapping Ground Deformation with Sentinel-1
On January 7, a magnitude 7.1 earthquake struck Tibet, triggering significant ground displacement. To analyze the surface deformation, I processed Sentinel-1 SLC data from January 5 and January 17 using SNAP, generating an interferogram that reveals how the earthquake reshaped the landscape. (Figure 1).Each fringe (the variation in color in the interferogram) represents a specific
Mapping the Valencia Floods with Sentinel-1
The recent floods in Valencia have caused extensive damage. To create a map of the affected areas, Sentinel-1A SAR (Synthetic Aperture Radar) imagery was utilized, offering reliable data to map and identify flooded zones, even under challenging weather conditions and cloud cover. For this analysis, two SAR images from Sentinel-1A were chosen: a pre-event image

A devastating explosion in Beirut on 4 August has killed at least 200 people and injured around 5,000 others. The disaster was preceded by a large fire at the Port of Beirut, on the city’s northern Mediterranean coast, later there was a colossal explosion that sent a mushroom cloud into the air and a supersonic blast
(43°N 142°E) Hokkaido: lattice structure
One of the more unusual features of Hokkaido, as seen from space, is a lattice-shaped windbreak forest found in the Konsen Plateau. This pattern is created by trees (primarily larch) planted in a lattice structure to protect farmland and livestock from bitterly cold, blowing winds. There is about 3 km (1.9 mi) between the lattices,
Flooding in Madagascar, a first assessment from Satellite
Madagascar is the world’s fourth largest island, and due to its position in the middle of Indian Ocean is regularly hit by cyclones between the months of November and April. The last tropical cyclone “Ava” hit the island country off the southeastern coast of Africa between the 5th and the 7th of January, killing at least 36
