New Delhi, (PTI) The Tongan volcanic eruption of 2022 caused large, rapid depletion of ozone by injecting huge amounts of water vapour into the stratosphere, a new research in the journal Science said.
The eruption notably injected an unprecedented amount of water vapour – about 10 per cent of the total global mean stratospheric burden – to very high altitudes of up to 55 kilometres, an international team of researchers from the US and Europe said in their study.
In just the one week following the eruption, the stratospheric ozone above the tropical southwestern Pacific and Indian Ocean region decreased by five per cent. The Antarctic ozone hole depletes up to 60 per cent of ozone from September to November, they said.
