The Hunga Tonga-Hunga Ha’apai eruption lasted less than a day, but it unleashed the most water vapor into the atmosphere by a volcano on record. Researchers say the blast may temporarily warm surface temperatures in years to come and also deplete stratospheric ozone.

On Jan. 15, the underwater volcano erupted and sent a shock wave that reverberated around the world. The powerful blast ejected aerosols, gas, steam and ash 36 miles high, probably the highest volcanic plume in satellite records. The blast damaged more than 100 homes and took at least three lives on the island of Tonga. A new study also shows the volcano released an unprecedented amount of water vapor, a strong greenhouse gas that traps heat on Earth.

The study stated the amount released is equivalent to 10 percent of the water already in the stratosphere.

How many nuclear weapons detonations would be required to offset the heating effect of the water vapor?
