Huge eruption of Bizymani volcano in Russia injects huge amount of ash into the atmosphere

Arab weather - Yesterday, Saturday 28-5-2022, a huge explosion was recorded for the Bezymyani-Kamchatka volcano in Russia, accompanied by lava flows and a huge column of smoke that reached a height of 15 km in the atmosphere, until the cloud of smoke extended horizontally to a distance of 365 km and moved towards Southeast, as a result of which the danger level for aviation was raised to red.

Satellite images have detected ash plumes and their large extension southeast of the volcano.

How does the eruption of the volcano affect the planes?

The explosive eruption of volcanoes is considered the most dangerous for aircraft because it produces several cubic kilometers of volcanic ash and aerosols that spread into the atmosphere and stratosphere within a few hours or days. It is able to retain an electrostatic charge and absorb water droplets and corrosive acids. The melting temperature of small ash particles is lower than the operating temperature of jet engines, and this poses a danger to aircraft engines and can cause scratches on the windows and windshields of the cockpit and impair visibility.

Ash plumes and clouds of smoke can travel thousands of kilometers and remain dangerous to aircraft, lasting for several days depending on the strength of the eruption and the intensity of the winds.

To reduce the risk of aircraft colliding with ash clouds to the Kamchatkan volcanoes, the international KVERT project was established, which provides an early warning service to aircraft about volcanic danger. Timely and avoid potential hazards to aircraft.

Effect of a volcano eruption on the climate

A volcanic eruption also has an impact on weather and climate. After an eruption, winds can carry fine ash from a volcanic eruption in the stratosphere to all parts of the world, and sulfur dioxide from volcanoes reacts in the atmosphere to form sulfate aerosols (aerosols are particles small suspended in the air), ash and aerosols scatter, or partially block, sunlight.

When the Tambora volcano in Indonesia erupted in 1816, one of the most powerful eruptions in recorded history, it released over 60 million tons of sulfur dioxide particles and aerosols that penetrated the upper layers of the atmosphere. The result was that the year 1816 was known as the year without summer, when a massive climate change occurred for a period of three years after the temperature of the planet decreased and weather disturbances prevailed, storms, snow, drought, diseases (cholera), revolutions of the hungry in Europe (famines), agricultural crop failures and economic depression, and he died as a result of That's millions.
