Mount Cameroon is an active volcano in Cameroon near the Gulf of Guinea. It is one of Africa's largest volcanoes, rising over 4,000 meters, with more than 100 small cinder cones. Mt. Cameroon has the most frequent eruptions of any West African volcano, having erupted most recently in 2012. It is part of the Cameroon Volcanic Line that also includes Lake Nyos, the site of a disaster in 1986. The image was acquired January 12, 2007, covers an area of 26.5 by 32 km, and is located at 4.2 degrees north, 9.1 degrees east.

With its 14 spectral bands from the visible to the thermal infrared wavelength region and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched Dec. 18, 1999, on Terra. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and data products.

The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.

The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate, Washington, D.C.
