Doom Plume

Short answer: Volcanologists call these eruption columns or ash plumes. In an explosive eruption, gas-charged magma shatters into ash, tiny fragments of rock and volcanic glass less than 2 mm across, which shoots out with steam and gases.

The jet first rises on its own momentum. It then keeps climbing because it is hotter and lighter than the surrounding air. Heights vary a lot. Iceland's Eyjafjallajökull plume in April-May 2010 mostly reached about 5-10 km, yet its fine ash drifting over Europe led to more than 100,000 cancelled flights. Mount Pinatubo's column in the Philippines on June 15, 1991, rose more than 35 km. The January 15, 2022, eruption of Hunga Tonga-Hunga Ha'apai reached about 57 km, into the mesosphere, the highest volcanic plume recorded in the satellite era. Ash is dangerous to aircraft because it can damage engines, instruments and windscreens, and it can stop jet engines. Health agencies such as the USGS and IVHHN list short-term effects including coughing, sore throats, eye irritation and worsening asthma or bronchitis. People with heart or lung conditions are most at risk. The footage shows a towering orange-lit ash cloud, but the Reel doesn't say which volcano.

Video transcript: Doom Plume: Ash That Climbs Into the Stratosphere

DID YOU KNOW? Volcanic debris plumes are enormous clouds composed of ash, rock fragments, and volcanic gases expelled violently during eruptions. Driven by explosive energy and heated gases, these plumes can soar tens of kilometers into the atmosphere, dispersing fine ash particles over vast areas. The debris within the plume can disrupt air travel, damage respiratory health, and impact ecosystems by coating land and water surfaces. NOW YOU KNOW!

The write-up

Ash that climbs into the stratosphere. Big eruptions loft ash plumes tens of kilometers high.

  1. Exhibit A

    What ash is

    Volcanic ash is shattered rock and volcanic glass, not soot. It forms when gas-charged magma blows apart.

  2. Exhibit B

    How high

    Pinatubo's 1991 column rose more than 35 km, and Hunga Tonga's 2022 plume reached about 57 km.

  3. Exhibit C

    Not always high

    Eyjafjallajökull's 2010 plume mostly stayed at 5-10 km, yet it still grounded more than 100,000 flights.

  4. Exhibit D

    Danger to jets

    Ash can damage engines, instruments and windscreens, and it can stop jet engines.

  5. Exhibit E

    Health

    Short-term effects include coughing, eye irritation and worsening asthma, especially for people with heart or lung disease.
