L’éruption du Hunga Tonga a envoyé des quantités d’eau colossales dans l’atmosphère : « Nous n’avons jamais rien vu de tel ! »

When a volcano erupts, there are lava flows and plumes of smoke. But when said volcano is a submarine volcano, there may also be ejection of water vapor into the atmosphere. And in the case of the Hunga Tonga-Hunga Ha’Apai volcano, which erupted last January, it involved colossal amounts of water vapor.

The eruption of the Hunga Tonga-Hunga Ha’Apai volcano produced very violent explosions and columns of ash 20 to 30 kilometers high.

Enough to fill almost 60,000 Olympic swimming pools!

“We’ve never seen anything like it”comments Luis Millán, a JPL researcher, in a release. According to their figures, they are nothing less than 146 teragrams, or 146 billion kilograms of water vapor that the Hunga Tonga volcano sent directly to the stratosphere — and even slightly higher — the layer of the atmosphere that is between 15 and 50 kilometers above the ground. This is almost four times more than what was expelled by the eruption of Mount Pinatubo (Philippines) in 1991. And no less than 10% of the total amount of water vapor already present at this level of the atmosphere.

This is all the more remarkable as it remains rare in several categories of volcanic eruptions.
There are three main categories of eruptions…” data-image=”https://cdn.futura-sciences.com/buildsv6/images/midioriginal/e/6/d/e6d4dc734e_124536_eruption-volcan-01.jpg” data – url =”https://news.google.com/planet/definitions/structure-earth-volcanic-eruption-455/” data-more=”Read more”>Volcanic eruptions inject steam into the stratosphere. Almost 20 years since the POT take readings. And that had only happened twice before. During the Kasatochi event (Alaska) in 2008 and during the Calbuco eruption (Chile) in 2015. In proportions far from being comparable, moreover. The excess water vapor had rapidly dissipated. This time, it could persist for up to ten years.

Consequences for life on Earth?

The problem is that the presence of water steam in the environment it is not as neutral and innocent as it might seem at first glance. Because in the stratosphere, water vapor tends to produce radicals that carry electrons “individual”. What makes them highly rated:
1. The reactant is not necessarily the species that reacts; thus, in the nitration of benzene, HNO3 is the reactant and the NO2+ cation is the reacting species.
2. The term “reagent” is also used as…” data-url=”https://news.google.com/sciences/definitions/chimie-reactif-4105/” data-more=”Read More”>reagents. They tend to destroyozone.

Water vapor also plays a fairly direct role in thegreenhouse effect. It is even a fairly effective greenhouse gas. Because it can absorb radiation. infrared emitted by our Earth in a wide range of frequencies. Therefore, the Hunga Tonga volcano eruption and the massive injection of water vapor that followed should have at least a one-time effect, potentially several years anyway, once the dioxide from General
