"The Hunga Tonga-Hunga Ha’apai volcano — which violently erupted in January 2022 and blasted an enormous plume of water vapor into the stratosphere – likely contributed to this year’s ozone depletion. That water vapor likely enhanced ozone-depletion reactions over the Antarctic early in the season.
“If Hunga Tonga hadn’t gone off, the ozone hole would likely be smaller this year,” Newman said. “We know the eruption got into the Antarctic stratosphere, but we cannot yet quantify its ozone hole impact.”
I mean there is still a massive hole in the ozone so I’m sot sure what you’re on about.

From a volcano, per the source you linked:

Not to make light of the situation, but Hunga Tonga makes me laugh.
I love the rhythm of this language. “Honga Tonga Honga Ha’apai” is so much fun to say.
