Laguna Colorada (Salar de Uyuni) photo by Federico Dell'anese
Laguna Colorada (Red Lagoon) is a shallow salt lake in the southwest of the altiplano of Bolivia, within Eduardo Avaroa Andean Fauna National Reserve and close to the border with Chile. The lake contains borax islands, whose white color contrasts with the reddish color of its waters, which is caused by red sediments and pigmentation of some algae.

To travel across Utah Highway 24 would be a psychedelic dream. A mixture of colorful and dramatically shaped rocks will guide you to the final destination.
Collapsed dam photo by Velio Coviello
This picture shows an earth dam collapsed after an intense rainy season in the Mogtedo basin, Burkina Faso. Facing recurring drought events and encroaching desertification, Sahelian countries are currently heavily affected by climate change. In the meanwhile, extreme rainfall events and high rainfall intensity are the main cause of soil erosion and land degradation but may also have an impact on hydraulic works.

Quarry in Qaradağ, Baku, Azerbaijan. In this quarry they are mining shelly limestone for building stone. The blocks are being mined by saw. Broken or imperfect blocks are being tipped over the edge of hill in the distance. The waste material is being used for dam construction.
Val Pola Landslide panorama photo by Martin Mergili
The Val Pola Rock Avalanche occurred on July 28, 1987. A total of 40-50 million cubic metres of rock were mobilized after a period of extensive rainfall. Besides destroying a number of villages and claiming dozens of lives, the mass movement impounded a lake and reshaped part of the upper Valtellina. Pizzo Coppetto (3066 m) behind the landslide, Bergamo Alps in the left central background.

Landslides at tropical environment conditions photo by Franny G. Murillo García
In October of 2013, many landslides were triggered by intense precipitations in the south of Mexico. One small town, Tonalapa, was one of the most affected, on the picture is possible identify more than ten mass movements. The soil exposed on the landslide scars is clay texture and red color. The dark, almost purple material is possibly quartz.
Active volcano photo by Franny Murillo, 1st prize IAEG 2014 Photo Contest
With 50-80° temperature, the green lake water at Chichón volcano in Chiapas, México, make evident the state of activity of this giant (crater size: 1km diameter). The color of the water ir related with the high sulfur content. The volcano made eruption in 1982 and is an important cultural element for the indigenous population near to the volcano. Each year, Zoque indigenous people, make a caravan to the volcano crater where ritual ceremonies try to "keep calm" the volcano.
Costa Concordia covered by the snow photo by Daniele Giordan
The CNR IRPI Geohazard Monitoring Group was involved in the Costa Concordia emergency team with a monitoring network composed by two robotised total stations. On February 11, 2012 a unusual snow event covers for few hours all the Giglio Island.

Detail of a tongue of Vatnajökull glacier complex, near Skaftafell, Iceland. Monitoring the evolution of glaciers over space and time is important to analyze, model, and understand global climatic changes.
Volcanoes, salars, and tornados photo by Andrea Manconi
Llullaillaco volcano (6,723 a.s.l.) as seen from the top of the Lastarria volcano (5,697 a.s.l.). Both active volcanoes are located in the Chile-Argentina border, and more specifically in the Atacama desert, which is considered one of the driest places on Earth. When evaporation exceeds the rate of water precipitation, salt pans (also known as salars) may form. The study of these areas with extreme climate conditions is important to better understand global climatic changes.

Georadar survey of permafrost in rock wall photo by Cadet Heloise, 3rd prize IAEG 2014 Photo Contest
A georadar survey has been realized in the North face of the Aiguille du midi, Chamonix, France, by ADRGT end EDYTEM. The goal was to provide the inside fracturation structure of this rock wall, considered as a permafrost zone. These walls are very sensitive to rock fall due to the presence of both permafrost and fracturation. The survey was a technical challenge, realized in alpine technics with hard weather conditions at 3800 m high!
