Tonga’s underwater volcano erupts during an eruption / WION NEWS
Nation World News, kilat.com- The intense eruption of Hunga Tonga-Hunga Hapai on January 15, 2022 broke all records for direct injection of water vapor into volcanoes or vice versa in the “satellite age”. It also sends large amounts of ash into the stratosphere.
According to a study published in Geophysical Letters, the massive eruption spewed water vapor up to a height of 53 km.

According to Live Science, the Hunga Tonga-Hunga Hapai volcano erupted with a force equivalent to 100 Hiroshima bombs, making it the most powerful eruption on Earth in more than 30 years.
The explosion shook the entire world, causing the atmosphere to “ring like a bell” and a tsunami hitting the adjacent beaches.

The explosion caused more than 590,000 lightning strikes in three days. Its clouds of ash and dust rose higher into the atmosphere than any previous eruption in history.
The massive explosion released some toxic gases and a lot of water into the atmosphere, which are now damaging our planet’s stratosphere. How much water evaporates from a volcano?
According to experts from the National Aeronautics and Space Administration (NASA), the University of Edinburgh and Northwest Research Associates, the explosion dumped enough water to fill 58,000 Olympic-sized swimming pools.
The Olympic standard pool is 50 meters long, 25 meters wide and 3 meters deep. What dangers can arise from water in the atmosphere?
In general, large amounts of SO2 are released into the atmosphere during volcanic eruptions, which cools the world. Surprisingly, Tonga does not emit much HCl or SO2.

“The climate impact of these eruptions may not be due to surface cooling due to sulfate aerosols, but to surface warming due to the radiative forcing of additional stratospheric H2O,” said the study
That means that extra water could radiate heat, warming the atmosphere and greenhouse gases, the researchers warn.
The warming effect of the water is likely to cancel out the cooling effect caused by the gas because it is expected to last longer than other volcanic gases such as sulfur dioxide, which typically fall from the atmosphere in two or three years.
According to geologists, this suggests that the Tonga eruption may have been the first known eruption to have a warming effect on the world rather than a cooling effect. (N.A.)
