The Hunga Tonga volcanic eruption that shook the South Pacific Ocean in January will not affect Earth’s climate despite sending clouds of ash dozens of miles high into the atmosphere, a new study confirmed. Powerful volcanic eruptions, such as the one that ripped apart the uninhabited Polynesian island of Hunga Tonga-Hunga Ha’apai on Jan. 15, … Read more
On Jan. 15, 2022, the Hunga Tonga-Hunga Ha’apai volcano erupted off the coast of Tonga in the South Pacific Ocean, generating a tsunami and triggering resulting wave action alerts around the world. The underwater volcanic eruption spewed ash, steam, and gas a radius of over 160 miles (260 kilometers) and more than 12 miles (19 … Read more
An underwater volcano in the South Pacific erupted last month and shattered two records simultaneously: The volcanic plume reached greater heights than any eruption ever captured in the satellite record, and the eruption generated an unparalleled number of lightning strikes — almost 590,000 over the course of three days, Reuters reported. “The combination of volcanic heat and the … Read more
When a volcano in Tonga erupted on January 15, it gave satellites their first glimpse at a plume of volcanic ash shooting into the mesosphere, the third layer of Earth’s atmosphere. According to NASA, the Tonga event was the largest volcanic eruption since satellites began monitoring our planet. As the Pacific volcano shot a burst of ash … Read more
The Hunga Tonga-Hunga Ha’apai eruption reached an explosive crescendo on Jan. 15, 2022. Its rapid release of energy powered an ocean tsunami that caused damage as far away as the U.S. West Coast, but it also generated pressure waves in the atmosphere that quickly spread around the world. The atmospheric wave pattern close to the eruption was quite complicated, but … Read more
The volcanic eruption in the South Pacific Kingdom of Tonga peaked on January 15 with more explosive force than 100 simultaneous Hiroshima bombs, NASA scientists reported on Monday 24 January. Using a combination of satellite and surface-based surveys, researchers calculated the explosive power of the volcano based on the amount of rock that was removed during the blast from the … Read more
When Hunga Tonga-Hunga Ha‘apai, a mostly submerged volcanic cauldron in the South Pacific Ocean, exploded on 15 January, it unleashed a blast perhaps as powerful as the world’s biggest nuclear bomb, and drove tsunami waves that crashed into Pacific shorelines. But 3 hours or so before their arrival in Japan, researchers detected the waves of … Read more
Scientists are starting to take the measure of the monster volcanic eruption that rocked the South Pacific kingdom of Tonga earlier this month. The undersea volcano had been burbling since late December 2021, shaking the seas near Tonga with a series of outbursts. Things kicked into higher gear this month, with powerful blasts on Jan. … Read more
A Lima zoo is racing to save dozens of seabirds, including protected penguins, left covered in oil after 6,000 barrels of crude spilled off Peru’s coast in the aftermath of the Tonga tsunami. More than 40 birds, including Humboldt penguins – listed as vulnerable by the International Union for Conservation of Nature – were brought … Read more
Astronauts on the International Space Station captured the aftermath of the massive volcanic eruption that tore up a small island in the Pacific Ocean and sent tons of ash into the atmosphere on Saturday (Jan. 15). Several weather satellites captured the eruption as it happened, revealing the massive cloud resembling a nuclear explosion that engulfed … Read more
