An aerial view shows a sinkhole 3.5 km (2 miles) to the east of Solikamsk-2 mine in Perm region, November 20, 2014. Shares in Russia's Uralkali, the world's top potash producer, fell sharply for a second day on Wednesday after a mine accident that could reduce global supplies and push up prices of the crop nutrient worldwide. Uralkali shares have fallen 28 percent since Tuesday when it suspended work at its Solikamsk-2 mine, which accounts for a fifth of the company's output and 3.5 percent of global capacity, following an inflow of water. A sinkhole, stretching 30 by 40 metres (yards), found at an abandoned mine 3.5 km (2 miles) to the east, increased concern about the future of the mine because an inflow of water and the resulting sinkhole in 2006 forced another Uralkali operation to shut permanently.

Jenny Odell repurposes online imagery mostly from Google Maps, but also from YouTube, Craigslist, and other sites. In her “Satellite Collections”, for example, she incorporated aerial views of swimming pools, basketball courts, parking lots, and other recognizable structures, seen from space. Her more recent series, “Satellite Landscapes”, includes painstakingly isolated Google Maps imagery of oil refineries, wastewater treatment plants, solar farms, etc. This work is meant as a reminder of our physically determined and vulnerable existence, since we depend on many of these things for survival and maintenance of our way of life.

Tens of thousands of vehicles damaged by super storm Sandy are being temporarily stored on runways and taxiways at Calverton Executive Airpark in Calverton, New York, on January 9, 2013 in this aerial view. Insurance Auto Auctions Inc, a salvage auto auction company specializing in total-loss vehicles, acquired the cars and trucks that were damaged, destroyed or flooded by the storm and needed a place to store them. The company made a deal with the Town of Riverhead to lease the airport land and then the vehicles are auctioned online. (Photo by Stan Honda/AFP Photo)
