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
Cyclone Chido: Sentinel-1 Captures the Storm’s fury
Cyclone Chido, a powerful tropical storm, swept across Mayotte, leaving a significant impact on the affected regions. Using Sentinel-1 radar data, we analyzed its structure and dynamics through high-resolution imagery and wind field data. On 2024-12-13, Sentinel-1 captured this striking image of Cyclone Chido, showcasing its spiraling rain bands and calm eye. The radar’s ability
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
Beirut explosion before and after 8 August 2020
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
[Top view] Wuhan
The images below represent Wuhan captured with SAR Copernicus Sentinel-1 and optical Copernicus Sentinel-2. Wuhan sits at the confluence of the Han River flowing into the Yangtze River at the East of the Jianghan Plain. The metropolitan area consists of three centers (Wuchang, Hankou and Hanyang) commonly called “Three Towns of Wuhan”. The name Wuhan is obtained by combining
(44.4982°N 92.3013°W) Lake Pepin
This image was acquired by Copernicus Sentinel-1 on Lake Pepin on 01/01/2020. It is the first image of this new year and decade. The Lake Pepin was formed by the delta of the Chippewa River, which flows into the Mississippi at the southwestern edge of Wisconsin. It is a naturally border between the U.S. states
( 16°49′S 151°27′W ) Raiatea and Taha’a
This Copernicus Sentinel-1 image acquired on February 2019 takes us over Raiatea and Taha’a islands located among the western group, the Leeward Islands, of the Society Islands in French Polynesia, an overseas territory of France in the Pacific Ocean. Raiatea, is the second largest of the Society Islands, after Tahiti, in French Polynesia, and its meaning “faraway heaven” and “sky with soft light,” is considered
(23°31′5″S 68°18′42″W) Salar de Atacama
The image represent the a salt flat, or playa, named Salar de Atacama captured with SAR of the Copernicus Sentinel-1. Chile’s Atacama Desert may be the driest place on Earth it is the world’s third largest salt flat (about 3000 sq km) as well as one of the largest active sources of lithium. Some areas of the
(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,
Island of California
The land of California existed as a myth among European explorers before it was discovered. The name “California” derives from a novel written by Garcia Ordonez de Montalvo in the 16th century titled, “Las Sergas del muy esforzado caballero Esplandian, hijo del excelente rey Amandis de Gaula.” It was the fifth book in a series of
