Mount Etna Lava is spewed across Sicily for weeks during a series of volcanic eruptions captured by a large number of satellites orbiting the Earth.
Etna, the most active volcano in all of Europe, has been in an eruption since 2011. The latest series has started On February 16, the volcano erupted that day, again on February 18 and then again between February 20 and 23. During these eruptions, lava fountains shot high into the night sky, reaching an altitude of 0.4 miles (0.7 km) earlier in the month and getting 0.9 miles (1.5 km) above the volcano’s summit later in the month.
The most recent volcanic eruptions were “among the fiercest in the young history of the southeastern crater”, Marco Neri, a volcanologist at the Italian National Institute of Geophysics and Volcanology, He said in a NASA statement.
Earth observation satellites were eager to check smoke, ash and lava emitted from volcano. On February 18, the Operational Ground Imaging (OLI) instrument on the NASA / US Geological Survey Landsat 8 satellite captured a natural color display of the volcano, which was covered with infrared data to show warm areas (or spots where the lava has penetrated).
Also on February 18, the European Space Agency’s Copernicus Sentinel-2 mission, consisting of two satellites, observed the eruption of the volcano. European satellites captured a moment that, using infrared imaging, showed the lava in a bright orange and red color.
A few days later, as Etna was erupting again on February 23, the US National Oceanic and Atmospheric Administration’s NOAA-20 satellite captured an image with the VIIRS instrument (Visible Infrared Radiometer array) highlighting the plumes coming from the volcano.

Landsat 8 observed the volcano again on February 25, this time at night. Using thermal infrared and short wavelength ranges, he was able to show the lava below based on the heat emitted from it.
While these recent eruptions were impressive, they caused minor disturbances rather than massive damage to the surrounding area, according to a NASA statement. Ash from Etna temporarily closed the airport in Catania and was deposited across Sicily, for example, and locals had to deal with falling ash and rocks.
