On 28 March 2025, a powerful magnitude 7.7 earthquake struck central Myanmar, sending shockwaves through the region. While the country is still dealing with the devasting aftermath, scientists have used radar images from the Copernicus Sentinel-1 satellites to reveal a detailed picture of how the ground shifted during the quake – offering new insights into the mechanics of the Sagaing Fault and the scale of the seismic rupture.
This image, which shows the fault line running north-south, is a radar image captured by Sentinel-1C on 2 April, after the earthquake.

Shout out to all my Subs and Bros out there now!
The 1/18 scale THS1 Barracuda has a removable hull top with a 4.5" x 10" interior containing three liftable seats. A separate bow cockpit holds not one, but two figures comfortably. Accessories include a removable control console and map table for underwater strategic planning. Blue flashing lights and submarine depth noises makes this one Bad Ass Sub!

El delta del Níger, es el delta del río Níger en Nigeria, una región densamente poblada a veces denominada los ríos de aceite ya que antiguamente la misma era una gran productora de aceite de palma. Desde 1885 y hasta 1893 la zona fue el Protectorado ríos de aceite británico, luego se expandió y se convirtió en el Protectorado costa del Níger.
Es uno de los 10 lugares más contaminados del mundo, destacando el vertido de Shell en 2008.
El delta del Níger, tal como lo denomina en forma oficial el gobierno de Nigeria, abarca unos 70,000 km² y representa el 7.5% del territorio de Nigeria. Tanto desde un punto de vista histórico como cartográfico,
A diferencia de los sensores ópticos, que registran la luz del sol reflejada en la superficie terrestres, los sensores de radar como el del satélite Sentinel-1 emiten sus propias ondas y registran el reflejo de estas procedente de la superficie. Tienen la gran ventaja de funcionar de noche y de atravesar las nubes.

The new image of #MozambiqueFloods detected by #Sentinel1. Flooded areas near Beira, Mozambique 🇲🇿 amounts to ~ 3300km2.
Latest image captured by #Sentinel2 (2019-03-22) shows till all the devastating signs of #MozambiqueFloods.
Here also the comparison between optical and SAR (by #Sentinel1) images before and after the flood.

Esta es la misma imagen anterior del salar de Uyuni (www.flickr.com/photos/migmasat/53123269556/in/dateposted-...), pero ahora en color verdadero. Aquí es donde podemos ver en toda su extensión el gigantesco manto blanco de sal.

The mountains around Poli, which don’t have a name as a range that I could find. Basically this process. The image is about 100 km wide. The source data is 16 VV+VH Sentinel-1 observations. For a while I thought I was seeing a seasonality signal but now I’m not so sure.

The Aleutian Islands extend between America and Asia across 2300 kilometers (1400 miles). The Islands of the Four Mountains are located on the eastern end of the chain, between the Fox Islands and the Andreanof Islands.
Islands in the IFM include Amukta, Chagulak, Yunaska, Herbert, Carlisle, Chuginadak, Uliaga, and Kagamil. All of these islands are volcanic, with Mt Cleveland on Chuginadak Island currently the most active. The IFM project is focused on three of these islands, Herbert, Carlisle, and Chuginadak.
Herbert Island is the westernmost of these three islands. It is approximately 10 km in diameter, is ca 1300 m in height, and has a rugged shoreline with high cliffs and very few bays.
Carlisle Island is the northernmost of the three islands and is also considered an active volcano although it has not erupted in recent times. It is 6.9 km in diameter and extends to 1610 m in height. Similar to Herbert, it has a rugged coastline with cliffs and deeply cut ravines with no bays or harbors.
Chuginadak is the largest of the Islands of the Four Mountains, 23 km by 9.7 km in size, and includes two mountain masses joined by an isthmus of coalesced lava flows and volcanic debris, with a stratovolcano, Mt Cleveland, on the west side of the island that extends to 1730 m in height. This island has protective harbors and inlets as well as rugged shorelines.
Some scenes from my recent deer hunting trip on Tug Hill. Easy to see why I don't see a lot of deer-too many distractions.
