Despite a recent decline in earthquakes, Ubinas Volcano erupted another ash plume on April 28, 2014. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) collected this false-color view of the area on the same day. Red in the image indicates vegetation.
Located in the Andes, Ubinas is considered the most active volcano in Peru, with intermittent small to moderate eruptions recorded since 1550. It had been showing signs of an impending eruption since mid-2013, highlighted by the appearance of a fresh lava dome in March 2014. Explosive activity began in mid-April, sending an ash cloud at least 4,000 meters (13,000 feet) into the air. Smaller explosions persisted through the end of April.
The recent eruption lead Peruvian officials to declare a state of emergency and to evacuate thousands of people and livestock (mostly llamas and alpacas). Ubinas’s frequent ash emissions are irritating the eyes and throats of thousands of local residents, especially children, according to El Economista, Peru.
