Mining Expansion in Western Australia
These Landsat images, acquired and distributed by the U.S. Geological Survey, show the changes to the jarrah (Eucalyptus) vegetation in the Muja State Forest around the small mining town of Collie in Western Australia. Expanding coal mines, power stations, and an alumina mine surround the urban area, and changes to the land can be seen when comparing these images acquired in 1990 and 2011.
Northwest of the urban area, an alumina refinery, constructed in the early 1980s, produces over 3 million tons of alumina each year. The water body south of the alumina refinery is the location of the Wellington Dam, which pushed the Harris River back to fill Lake Ballingall (top-central part of the image). South and east of the town, numerous coal mines provide fuel for a number of power stations in the area.
Landsat imagery is used by decision makers worldwide for future planning and land change analysis.
