Volcanoes are wonderful forces of nature. They can be intimidating when exploding and even beautiful when seen by a safe point of the edge on Earth. Satellite images give us a very different perspective on an explosion. NASA shared a look at Italy’s Mount Etna in the middle of the dress, as seen from the landsatin satellite on February 13. The satellite caught the viewing of a wonderful “Fire River”.
Mount Etna’s latest riots began on February 8 with some stories rumors. The eruptions are not uncommon for the volcano. “But the fiery explosions, the clouds of the divisive ash, and the long lava flows that followed stayed as extremely spectacular for many Etna observers,” Nasa said.
Mount Etna from space
NASA’s land observatory, a site dedicated to public extension regarding our planet, posted satellite photo as an image of the day on February 20th. The top-down view looks at the clouds on Mount Etna. Gray snow, stained by ashes, appears under a volcanic plaque. It is a dramatic scene.
NASA with bright red beam described as a “fire stream” is not what you will see with the naked eye. “The natural color scene is lined with an infrared signal to distinguish the sealing of the lava heat on the snowy slopes of Etna,” the space agency said. The flow was measured at about 2 miles in length at the time of the figure. The lava river traces a crack at the Bocca Nuova Crater base of the volcano, according to a report from the Global Global Volcano Program of the Smithsonian institution.
Landsat 8, a cooperation between NASA and the United States geological survey, was started in 2013. The mission monitors land and water use and supports catastrophe estimates and responses. The satellites that observe the soil are useful for tracking the flows of lava and ash of air and gases from volcanoes. This information can keep people safe on the ground and in the air.

Drone view of Mount Etna
The National Institute of Geophysics and Volcanology of Italy (IngV) shared the footage of the latest Etna lava drone on February 17th. A video shows a thermal view and an optical view of the area. The molten lava looks gray in the free eye, but hot areas appear in the thermal view.
Mount Etna is one of the most active Stratovolcanot in the world. Stratovolcania have a conical shape and steep sides formed by layers of volcanic material. Mount Hood in Oregon and Mount St. Helens in Washington are well -known Stratovolcanoes in the United States.
The mood changes of a volcano can affect the world around it. Etna ash plums sometimes result in plane deviations. Inevitably boil again. “The explosion has been continuing since February 18, with poor ash emissions and declining explosive activity,” NASA said.
Mount Etna has a long record. “The explosive history of the volcano can be traced to 500,000 years and at least 2,700 years from this activity has been documented,” UNESCO’s entry for Mount Etna told the World Heritage List.
Satellites have advanced the way Mount Etna’s documentation. The images are beautiful and informative. Grace from the last explosion has been more worrying than lava, but lava makes a stunning view of space with little help from infrared data.
