    I continue to be amazed at the power of this explosion and the complete lack of coverage of the impact that this volcano is having on the weather patterns around the world. Perhaps it isn't totally understood or is it willful ignorance or ??? The explosion placed more water vapor int he upper atmosphere than any event ever recorded or modeled in the history of human record keeping. It is now projected that the original tsunami from this event was nearly as tall as the empire state building

    Tonga volcano sent tons of water into the stratosphere, which could warm Earth : NPR

    The violent eruption of Tonga's Hunga Tonga-Hunga Ha'apai volcano injected an unprecedented amount of water directly into the stratosphere — and the vapor will stay there for years, likely affecting the Earth's climate patterns, NASA scientists say.

    The massive amount of water vapor is roughly 10% of the normal amount of vapor found in the stratosphere, equaling more than 58,000 Olympic-size swimming pools.

    "We've never seen anything like it," said atmospheric scientist Luis Millán, who works at NASA's Jet Propulsion Laboratory. Millán led a study of the water the volcano sent into the sky; the team's research was published in Geophysical Research Letters.

    The volcano sent vapor and gases to a record height
    The Jan. 15 eruption came from a volcano that's more than 12 miles wide, with a caldera sitting roughly 500 feet below sea level. One day earlier, Tongan officials reported the volcano was in a continuous eruption, sending a 3-mile-wide plume of steam and ash into the sky. Then the big blast came, sending ash, gases and vapor as high as 35 miles — a record in the satellite era — into the atmosphere.

    The Tonga eruption may have spawned a tsunami 90 meters tall | Science News

    The massive Tonga eruption generated a set of planet-circling tsunamis that may have started out as a single mound of water roughly the height of the Statue of Liberty.

    What’s more, the explosive eruption triggered an immense atmospheric shock wave that spawned a second set of especially fast-moving tsunamis, a rare phenomenon that can complicate early warnings for these oft-destructive waves, researchers report in the October Ocean Engineering.

    As the Hunga Tonga–Hunga Ha’apai undersea volcano erupted in the South Pacific in January, it displaced a large volume of water upward, says Mohammad Heidarzadeh, a civil engineer at the University of Bath in England (SN: 1/21/22). The water in that colossal mound later “ran downhill,” as fluids tend to do, to generate the initial set of tsunamis.

    It really is amazing, and I'm kind of surprised at myself, given how much I read on volcanism and seismicity, that I have not been tracking it more closely. Thanks for sharing.

    I still obsess over Krakatoa 1883. Every time I see the name of the Yellowstone Creek well I think it's about Krakatoa

    The fact that it was out at sea makes it mainly a scientific exercise, which doesn’t draw people in.
    It is interesting stuff though.

    I wonder if the additional water spewed into the atmosphere is the cause of all these so-called once-in-a-century (now more like once-a-month) flooding events?

    Everything hangs together in a delicate balance. It doesn't take much to disrupt it, often with unpredictable consequences.

    I wondered the same. Krakatoa impacted world weather for years. But eruptions usually cause cooling and change the color of the sky. Not sure if this particular output would have the opposite effect

    more from the article on how the injection of water vapor interrupted a cycle so repetitive that it is known as the heartbeat of the atmospheric water pattern

    The normal mechanism by which water rises into the stratosphere is so reliable that researchers refer to it as a sort of tape recorder, marking annual temperature cycles through alternating bands of dry and moist air rising from the tropics.

    middle of the dry period in that seasonal cycle — but then the Tongan volcano erupted in the South Pacific Ocean, suddenly injecting a huge amount of water high in the atmosphere.

    "By short-circuiting the pathway through the cold point, [Hunga Tonga-Hunga Ha'apai] has disrupted this 'heartbeat' signal" in the planet's normal atmospheric water pattern, the researchers said.

    this will have opposite effect. normal volcano injects ash and dust which reflects light. increase inw ater vapor will trap heat

    EarthSky | New record: Tonga volcano biggest of 21st century

    Tonga was as big as Krakatoa
    The volcanic blast that destroyed the uninhabited island of Hunga Tonga Ha’apai on January 15, 2022, is now officially the largest explosive eruption of the 21st century so far. And it was the largest since the 1991 eruption of Mt. Pinatubo in the Philippines. The size of the Tonga explosion makes it the largest ever recorded by modern sensor technology. Measurements of the pressure wave the blast created – which traveled around the world four times over a six-day period – was equivalent to the 1883 eruption of the infamous Krakatoa.

    Biggest boom ever recorded
    The explosion created an event that has never been seen before in recorded history. Tonga blew ejecta well into the upper atmosphere, to the edge of space. It created a cloud that covered an area approximately half the size of France.

    Thanks. So what would that mean in terms of the weather that all of us experience, if anything? You seem to be more technically savvy on these matters.

    Thanks.

    By the way, I'm going to be a Republican and deny the science that says Tonga is as big as Krakatoa. I've been obsessed with Krakatoa since I was a child, and I'm not going to give that up and change my worldview on something as insignificant as scientific measurements. ;>

    correction, you are going to be a MAGA pub, a peculiar, specific subspecies with a unique ability to refuse to acknowledge anything that they don't want to believe to be true.

    no idea, not technically savvy, just a simple parrot that read that in one of the articles I couldn't find to quote

    I thought the same thing but the consensus in what I have read indicated that the water vapor would remain in the upper atmosphere for years.

    Which surprised me because of the temperature in the upper atmosphere. Wouldn't the water vapor freeze and as it forms larger pieces of ice, start to fall out of the sky?

    i got nuttin. One would think that the weather geeks would be all over this story.

    I also wonder if the increased water vapor would increase drag on spaceships during reentry and require a better heatshield

    Students of or those interested in Volcanology are. While I am no expert, I am interested in the subject. -Geology, Extinction Events and Climate shifts, related to Volcanology SHOULD BE, of immense concern the world over.

    The Deccan Traps, and similar mind boggling volcanic events could alter the course of human history rapidly.

    The worst recorded year in human history (Aro) 534 or so, is often theorized to have had its origins from a volcanic eruption in either Iceland or possibly Krakatoa.

    Perhaps people are unaware that the planet is in a relatively quiet mode of volcanic activity, much like the stable climatic system we humans have enjoyed since the Yonger Dryas.

    Do people know that the Hawaiian Island chain is created by a massive volcanic vent? As the tectonic plate moves and that vent erupts it creates what we know as the Hawaiian Islands.

    Then of course there is Yellowstone, but actually there are several potential VI 7 or 8 Caldera areas that could blow in various parts of the world that would change everything for humanity.

    People worry about Cosmic Impacts but Volcanic annihilation is much more likely.

    I knew about Hawaii and Yellowstone. I hiked out years and years ago and watch the lava flow into the ocean on the big island. There is a subsea vent east of the big island flowing and building another island. The slow shifting of the crust is why Kauai is the oldest and Hawaii the youngest. There is a show out there about what would happen if and when Yellowstone were to go off again. Cataclysmic level destruction and ice age

    A picture is worth a thousand words. This looks like multiple nuclear bombs going off. How about the lightning?
