It also changed the chemistry and dynamics of the stratosphere in the year following the eruption, leading to...

Here is the late info on the Hunga Tonga volcano

On Saturday, the volcano at Hunga Tonga-Hunga Ha’apai erupted, sending ash plumes 30 kilometres into the atmosphere, kicking off a tsunami in Tonga that reached as far away as Alaska, and destroying a volcanic cone that connected the uninhabited islands of Hunga Tonga and Hunga Ha’apai. The volcano is around 65 kilometres northwest of Tongan capital, Nuku’alofa, with experts saying it was one of the most powerful eruptions since the 1990s. “The sea level gauge at Nuku’alofa, Tonga, recorded a tsunami wave of 1.19 metres before it stopped reporting,” Dr Hannah Power of the University of Newcastle said. “Waves of...

Scientists are struggling to monitor an active volcano that erupted off the South Pacific island of Tonga at the weekend, after the explosion destroyed its sea-level crater and drowned its mass, obscuring it from satellites. The eruption of Hunga-Tonga-Hunga-Ha’apai volcano, which sits on the seismically active Pacific Ring of Fire, sent tsunami waves across the Pacific Ocean and was heard some 2,300 kms (1,430 miles) away in New Zealand. “The concern at the moment is how little information we have and that’s scary,” said Janine Krippner, a New Zealand-based volcanologist with the Smithsonian Global Volcanism Program. “When the vent is...

Last week’s eruption of the volcano near the Pacific island nation of Tonga was 600 times more powerful than the nuke dropped on Hiroshima, Japan, in World War II. As a result, the eruption was so loud that many Tongans went deaf after the first explosion. “The first explosion…our ears were ringing and we couldn’t even hear each other, so all we do is pointing to our families to get up, get ready to run,” Marian Kupu, a journalist on Tonga, told Reuters. The eruption was so loud that it could be heard across the world, even thousands of miles...

The eruption of Hunga-Tonga-Hunga-Ha'apai volcano, which sits on the seismically active Pacific Ring of Fire, sent tsunami waves across the Pacific Ocean and was heard some 2,300 kms (1,430 miles) away in New Zealand. [O]n-site instruments were likely destroyed in the eruption and the volcanology community was pooling together the best available data and expertise to review the explosion and predict anticipated future activity. Saturday's eruption was so powerful that space satellites captured not only huge clouds of ash but also an atmospheric shockwave that radiated out from the volcano at close to the speed of sound. Photographs and videos...

AAP/Japan Meteorology Agency Why the volcanic eruption in Tonga was so violent, and what to expect next January 15, 2022 3.04pm EST Shane Cronin, University of Auckland Author Shane Cronin Professor of Earth Sciences, University of Auckland The Kingdom of Tonga doesn’t often attract global attention, but a violent eruption of an underwater volcano on January 15 has spread shock waves, quite literally, around half the world. The volcano is usually not much to look at. It consists of two small uninhabited islands, Hunga-Ha’apai and Hunga-Tonga, poking about 100m above sea level 65km north of Tonga’s capital Nuku‘alofa. But hiding...

Residents of the South Pacific nation of Tonga are experiencing a total Internet shutdown after an underwater cable which connects the island to the rest of the world was severed, possibly by the anchor of a large ship. It doesn't just mean that the isolated country can't access Facebook and YouTube - it's also affected email, airline bookings, university enrollment, money wires and prevented businesses from processing credit and debit cards - throwing the small country into chaos as they face up to weeks of Internet isolation. A ship from nearby Samoa will be sent out to fix the severed...

The Pacific nation of Tonga is waiting to see if it has a new island, after an underwater volcanic eruption forced a column of smoke and ash into the skies near the country's capital, Nuku'alofa. The eruption began on Monday after an earth tremor and is still sending clouds of smoke, steam and ash up to 100 metres into the air. Seismologists say the tremor was between the low-lying twin volcanic islands of Hunga Tonga and Hunga Ha'apai, an area where around 36 undersea volcanoes are situated. Kelepi Mafi from Tonga's Ministry of Lands says a marine survey will begin...

When an underwater volcano in Tonga erupted in January, it belched out more than ash and volcanic gases; it also spewed 58,000 Olympic-size swimming pools' worth of water vapor into Earth's atmosphere, a new study finds. This water vapor could end up being the most destructive part of the volcano's eruption because it could potentially exacerbate global warming and deplete the ozone layer, according to the study. When the Hunga Tonga-Hunga Ha'apai volcano erupted on Jan. 15, it became the most powerful explosion on Earth in more than 30 years, with an equivalent force of 100 Hiroshima bombs.
