Kilauea's eruption photographed by Nasa satellites
The image taken by Aster
NASA satellites captured the devastating eruption of volcano Kilauea that has began on May 3rd (see for details AVIONEWS article connected). The photos captured by the "Earth" satellite were taken on May 6th and show from a particular point of view new cracks caused by the volcano's lava.
In the photographs it is possible to notice the areas covered with vegetation highlighted in red, the new cracks in yellow and the old lava flows in grey and black. In another shot captured on the same day you can instead identify the sulfur dioxide spills, marked in green and yellow. The dangerous gas is a real risk to health and air pollution since it can give rise to acid rain and it can change the climatic rhythms and be very harmful or lethal if breathed at high concentrations.
The images were captured by the "Earth" remote sensing satellite (Eos AM-1) thanks to Aster (Advanced spaceborne thermal emission and reflection radiometer) one of the five remote sensors active on board since February 2000. "Earth" is part of the Earth Observing System program (Eos) and was placed in geostationary orbit in 1999.
