A four-week earth science mission to Guatemala brought back research on ground deformation in this active region — and a gorgeous shot of volcanoes upon volcanoes.
The stunning volcano image was taken from NASA's C20-A aircraft during an ongoing mission to 10 locations, including the volcanoes of Central and South America. The modified Gulfstream III is carrying an instrument called the Uninhabited Aerial Vehicle Synthetic Aperture Radar, according to NASA.
The radar-imaging mission is hitting several research hotspots, including the Gulf Coast of the United States. The goal is to provide data on everything from land deformation near volcanoes, which can indicate imminent activity, to vegetation data in forested areas. Other features under scrutiny are levees and glaciers. [Amazing Images of Volcanoes from Space]
All of the volcanoes in this image are active. The conical volcano in the middle of this image is Volcán de Agua, a 11,500-foot-tall (3,500 meters) mountain that sits a few miles from Antigua, Guatemala, a city of about 35,000 people and a UNESCO World Heritage site. The volcano gets its name from a lahar, or mudflow, that occurred in 1541, because of the watery flood associated with this event.
Behind Volcán de Agua are two peaks. The one on the right is Volcán de Fuego — the Volcano of Fire, which smolders at a low level almost daily. The last large belch from the volcano occurred in September 2012, leading to the evacuation of more than 30,000 people from nearby villages.
Next to Volcán de Fuego is Acatenango, which erupted in the 1920s and again in 1972, though those eruptions did not involve explosive ejections of ash and lava. The last explosive eruption of the volcano was about 1,900 years ago.
Finally, the stocky-looking volcano in the foreground is Volcán de Pacaya, which sent ash flying nearly 2 miles (3 kilometers) into the atmosphere on March 2, according to the Eruptions blog on Wired.com. The slopes of the volcano are home to Pacaya National Park, a popular tourist attraction.
