The psychedelic satellite image of Mount Etna




After ten months of what experts call a 'low simmer',  Italy’s Etna volcano boiled over on February 19th, with three massive outbursts in 36 hours.
According to the Italian Istituto Nazionale di Geofisica e Vulcanologia, each outburst (paroxysm) featured 'emission of lava flows, pyroclastic flows, lahars, and an ash cloud.'
Luckily, NASA captured the first from a passing satellite - and today revealed the picture that shows an eruption from above in unprecedented detail.

NASA'a Advanced Land Imager satellite captured Mount Etna on February 19 at 9:59am Central European Time, about 3 hours after the end of the first eruption. The false-color image combines shortwave infrared, near-infrared, and green light in the red, green, and blue channels of an RGB picture, making it easier to differentiate between lava, snow, clouds and forest.

What it shows: Nasa tweaked the image colours to make it easier to distinguish between the various parts of the eruption and surrounding area

The 'real' image of Mount Etna from space shows a far more bland version of events
