Mount Etna is erupting and astronauts are watching it from space

The majestic Mount Etna is erupting so strongly in the Mediterranean that it's
catching the attention of the International Space Station crew.

Members of Expedition 66 currently in orbit shared some views of space of the
highly active volcano, which has erupted dozens of times in the past year
alone. 

On the Russian side of the space station, cosmonaut Anton Shkaplerov of
Roscosmos, the Russian space agency, also sent a report down from orbit.
"Red-hot lava flows out of the crater, and clouds of ash and smoke are in the
sky over Sicily. The activity of the volcano then stops, then resumes with a
series of powerful explosions 🌋."

Not a very clean shot since there is way too much humidity in Europe’s air at the moment but @astro_luca's home volcano #Etna is clearly smoking (and spitting lava as I learnt from the news) 🌋 pic.twitter.com/gL5uNOkZUy

Mount Etna was so active in 2021 that it grew by 100 feet (30 meters) in half
a year. Astronauts can assist with satellite observations of natural phenomena
such as volcanoes and hurricanes snapping their own photographs from the ISS.

Volcanic plumes can reach very high altitudes and can potentially impact air
traffic, while sulfur dioxide closer to the ground can irritate the human
respiratory system and trigger asthma or other respiratory conditions.

Mount Etna is believed to be a submarine volcano that popped above sea level
after several eruptions, due to solidified lava, according to NASA's Earth
Observatory. The mountain has lava flows over its surface that date to as far
back as 300,000 years ago.
