Factbox: What’s known about the Russian volcano that may be about to erupt?

Scientists believe that the Shiveluch volcano in Russia’s far east Kamchatka peninsula may be preparing for its first significant eruption in 15 years.

In the vast region of the Earth known as the “Ring of Fire,” which circles the Pacific Ocean and is subject to eruptions and frequent earthquakes, Kamchatka is home to 29 active volcanoes.The majority of the volcanoes on the peninsula are surrounded by sparsely populated woodland and tundra, so they don’t represent much of a hazard to the local population. However, large eruptions can shoot glass, rock, and ash into the air, endangering airplanes.
These eruptions, which need the rerouting of air traffic, often occur three or four times a year in Kamchatka, according to the United States Geological Survey (USGS).

SHIVELUCH
Shiveluch, one of the peninsula’s most active volcanoes with a top elevation of 3,283 meters (10,771 feet), is thought to have erupted 60 times in the preceding 10,000 years.The Kamchatka Volcanic Eruption Response Team said on Sunday that it has become extremely active and poses a threat of a large eruption.

The observatory reported that the lava dome’s expansion is continuing, along with severe fumarole activity, incandescence of the lava dome, explosions, and hot avalanches.

Fumaroles are openings through which hot sulphurous gases emerge, and domes are mounds created by lava that has accumulated.

According to KVERT, an eruption that may endanger international flights has been given an “Orange” threat level, indicating that it is likely to erupt.According to NASA, the volcano’s most recent and strong eruption occurred in 2007. The Far East Branch of the Russian Academy of Sciences’ Institute of Volcanology and Seismology director, Alexei Ozerov, stated on Sunday that the volcano’s dome was extremely hot.

“The dome shines almost completely throughout its surface at night. Pyroclastic flows drop as hot avalanches with temperatures of 1,000 degrees Celsius (1,832 degrees Fahrenheit) slide down the hillsides. Typically, the dome is in this state prior to a strong paroxysmal eruption “said he.
