L 'Etna in Italy is infamous throughout history and timesmodern for its eruptions. The very active volcano sparked another eruption last week and a European Space Agency satellite returned extraordinary views from space.
The Copernicus Sentinel-2 mission followed Etna 's latest explosion. The dramatic images released by ESA highlight the lava flow in the infrared, causing it to appear in fiery colors. Science

Sunday's ESA view of Etna is a detailed top-to-bottom view showing a late ash cloud, two main lava flows and fluffy white clouds nearby. The volcano spat ash onr the neighboring city of Catania.

In a statement from Friday , ESA described the eruption of the volcano on February 16 as a "mighty " with lava fountains bursting into the night sky and reaching heights of 700 meters.
The initial eruption sent lava towards the sky. is at the bottom of the mountain, while a second major explosion a few days later generated a southern lava flow. Both stretches are visible in satellite images.
The satellites have become valuable tools for monitoring volcanoes and the impact of large eruptions. "Once an eruption begins, optics and radar instruments can capture the phenomena associated with it, including lava flows, mud , ground cracks and earthquakes, ”said esa.
The views from the ground were also revealing. A US Navy group in Europe Volcano Discovery has tracked Etna and the seismic activity associated with the volcano. The data suggests that that may not yet be done with this series of spectacular eruptions and lava fountains.
