Satellite radar image from the TerraSAR-X sensor of the summit of Cleveland Volcano showing the summit crater and growth of the lava dome. The summit crater is about 200 meters across. Note that satellite radar images have some inherent topographic distortion due to the manner in which they are collected. Picture Date: August 29, 2011. Credit: Dave Schneider, Zhong Lu, AVO/USGS.

The East African Rift is one of the great tectonic features of Africa, caused by fracturing of the Earth’s crust. This astronaut photograph of the Eastern Branch of the Rift (near Kenya’s southern border) highlights the classical geologic structures associated with a tectonic rift valley.

Tinakula is a small, volcanic island in the South Pacific, located about 2,300 kilometers (1,400 miles) northeast of Brisbane, Australia. This natural-color satellite image (top) shows a plume of volcanic gas, possibly mixed with a bit of ash, rising above the island’s summit. (via NASA Earth Observatory)

Ayers Rock and the Amadeus Basin (by europeanspaceagency) This Landsat 5 image, acquired on 18 May 2011, takes us to the Amadeus Basin in the heart of the Australian outback. Two large rock formations are visible on the lower section of the image. The group of 36 domed rock formations to the west (left) is the Kata Tjuta with the tallest dome, Mount Olga, reaching 1066 m above sea level. Forty kilometres east of Kata Tjuta is Ayers Rock, known to the Aboriginals as Uluru. The white area at the top of the image is the salt-crusted Lake Amadeus. ESA supports the Landsat series as a Third Party Mission, meaning it uses its ground infrastructure and expertise to acquire, process and distribute Landsat data to users. Credit: USGS.

Dune Patterns (by Lunar and Planetary Institute) Data from NASA’s Cassini spacecraft show that the sizes and patterns of dunes on Saturn’s moon Titan vary as a function of altitude and latitude. The dunes in areas that are more elevated or are higher in latitude, such as in the Fensal region pictured at bottom left, tend to be thinner and more widely separated, with gaps that have a thinner covering of sand. Dunes in the Belet region, pictured at top left, are at a lower altitude and latitude. The dunes in Belet are wider, with thicker blankets of sand between them. The Kalahari dunes in South Africa and Namibia, located in a region with limited sediment available and pictured at bottom right, show effects similar to the Fensal dunes. The Belet dunes on Titan resemble Earth’s Oman dunes in Yemen and Saudi Arabia, where there is abundant sediment available. The Oman dunes are shown at top right.

With advances in the methods of interferometry, subsidence of entire countries can now be mapped. This image shows the average displacement rates over millions of permanent scatterers identified over Italy using data from ESA’s ERS missions (1992–2001). The project was financed by the Italian Ministry of the Environment and carried out by e-GEOS, TRE and Compulab. Credit: Tele-Rilevamento Europa (TRE). (vía ESA)

Earth from Space: Algerian sands (by europeanspaceagency) This image shows the sandy and rocky terrain of the Sahara desert in western Algeria. With the Mediterranean Sea almost 500 km away, the closest town to the area pictured here is Taghit in the Algerian province of Béchar. The commercial Ikonos-2 satellite acquired this image on 23 April 2008 at a spatial resolution of 4 m. Credit: EUSI.

The image above shows the eastern part of Grand Canyon National Park in northern Arizona, near 36 degrees north latitude and 112.1 degrees west longitude. It is a composite of two pieces: a synthetic natural color image captured on July 14, 2011, draped over a three-dimensional model of the area. The images and stereoscopic data behind the model were acquired by the Advanced Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra spacecraft. The perspective is from east to west, looking down the channel of the Colorado River. North is to the right. In this view, the canyon spans 9 miles (14.5 kilometers) at its widest point and 5,600 feet (1,707 meters) from rim to river bed. The North Rim and Walhalla Plateau stand out on the right side, while Grand Canyon Village rests on the high plateau at upper left. (vía NASA Earth Observatory)

Mount Kilimanjaro’s peak in north-eastern Tanzania captured by the US-operated GeoEye-1 satellite.

Russia’s northernmost territory, Franz Josef Land, is an archipelago of 191 islands in the northeastern Barents Sea. On August 17, 2011, clear skies allowed the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite this unobstructed view. Clouds fringe this natural-color scene, like curtains held back from a window. Around the islands, sea ice forms serpentine shapes of light gray and dull white. The glaciers that cap many of the islands are bright white. In ice-free areas, land cover is pale brown, typical of tundra. (via NASA Earth Observatory)

Earth from Space: Summer in bloom (by europeanspaceagency) The phytoplankton bloom pictured in this Envisat image stretches across the Barents Sea off the coast of mainland Europe’s most northern point, Cape Nordkinn. Although most types of phytoplankton are individually microscopic, the chlorophyll they use for photosynthesis collectively tints the colour of the surrounding ocean waters. This allows for these tiny organisms to be detected from space with dedicated ‘ocean colour’ sensors, such as Envisat’s Medium Resolution Imaging Spectrometer, which acquired this image on 17 August 2011. Credit: ESA. Yes, that bloom really is that color…

Stratigraphy of Kasimov Crater Fill (by Lunar and Planetary Institute) This image shows layered sedimentary rocks and ripples that fill and surround Kasimov crater. These layered deposits may have formed through the accumulation of sediment that was transported into this crater by blowing wind. The crater interior contains a sequence of layers that are remnants of the material that originally infilled the crater. These sediments form an extensive deposit that once covered the floor of the surrounding larger crater.
