'One day it will just go off': are Naples' volcanic craters at Campi Flegrei about to blow?

Campi Flegrei
© Roberto Salomone/The GuardianSmall hills dot the landscape of Campi Flegrei. Campi Flegrei, a constellation of ancient craters in the south of Italy, is more active than Vesuvius, and residents live with daily tremors.
To the right is the Gulf of Pozzuoli, where the Mediterranean Sea laps the distant islands of Procida and Ischia. Directly in front is Solfatara, a shallow volcanic crater whose sulphurous vapours are known for their therapeutic benefits.

But for Cammarota, who has lived in the apartment for more than 30 years, the view is a constant reminder of the menace bubbling beneath the surface.

Solfatara is located in Campi Flegrei, a constellation of ancient volcanic craters near the southern Italian city of Naples, parts of which were described in a study this month as edging towards "breaking point".

Tonga's Hunga eruption produced the highest-altitude lightning flashes ever

The eruption produced 2,600 flashes per minute.

The 15 January 2022 eruption of Tonga’s Hunga Volcano produced a “supercharged” storm in the plume that had the most intense lightning ever recorded in a storm, according to a new study in AGU’s journal Geophysical Research Letters.

The Hunga Tonga - Hunga Haʻapai volcano in the South Pacific Ocean erupted on January 15, 2022, continuing to break records. The eruption generated a plume of ash, water, and magmatic gas at least 58 kilometers (36 miles) high. Despite blocking satellite views of the vent and making it more challenging to monitor changes in the eruption as it progressed, the towering plume provided scientists with vital information about the eruption's size.

A new study revealed that the eruption created a "supercharged" thunderstorm that recorded the most intense lightning ever. During the eruption, there were approximately 200,000 lightning strikes in the volcanic plume, with the rate reaching a maximum of over 2,600 strikes per minute, according to the experts.

Scientists have now been able to gaze into that plume, plucking out new stages of the eruption's life cycle and obtaining insight into the strange weather it caused thanks to high-resolution lightning data from four sources previously never used together.

Eruption of the Klyuchevskaya Sopka volcano in Kamchatka, Russia

,,,,,,,,,,,,,
An eruption has begun on the Klyuchevskaya Sopka volcano, Olga Girina, head of the Kamchatka Volcanic Eruption Response Group at the Institute of Volcanology and Seismology of the Far Eastern Branch of the Russian Academy of Sciences, told RIA Novosti.

"An eruption of the Strombolian type began on the Klyuchevskaya volcano tonight. Satellite images show a bright thermal anomaly, a spasmodic tremor is recorded. There are no ash emissions yet," Girina said.

At night, there was a glow from the lava, which had already appeared in the western part of the summit crater. This was recorded by CCTV cameras installed at the observatory in the village of Klyuchi.

The volcano has so far been assigned a "yellow" increased hazard code for aviation, since there are no ash emissions. If the activity increases significantly, emissions may pose a danger to air vehicles.

Philippines evacuates people near Mayon Volcano, where more unrest indicates an eruption is coming

Philippine troops, police and rescue workers began forcibly evacuating residents near Mayon Volcano on Friday as its increasing unrest indicated a violent eruption of one of the country's most active volcanoes is possible within weeks or days.

The area within a 6-kilometer (3.7-mile) radius of Mayon's crater is supposed to be off-limits due to possible volcanic emissions, lava flows, rockfalls and other hazards. But many poor villagers have built houses and tended farms in Mayon's danger zone over the years.

President Ferdinand Marcos Jr. said an evacuation of residents from the permanent danger zone was underway and promised to provide aid to the displaced until the crisis ended.

"Right now, what we are doing is preparing and moving people away from the area so that, should the time come, I hope it doesn't happen...we're ready," Marcos told reporters. "But unfortunately science tells us that may happen because the lid or the cap on top of the lava is slowly rising."

Stunning footage from Hawaii shows an active volcano erupting and spewing molten hot lava.

Kilauea volcano in the Halemaumau Crater is erupting again and began at around 4.45am today, the US Geological Survey (USGS) said.

Scientists discover rare methane-spewing underwater volcano in Norwegian waters

Scientists have discovered a submarine volcano near Norway's Bear Island, or Bjørnøya, in the Barents Sea, which continuously spews methane and mud.

The scientists also revealed that the volcano was located inside a giant crater, which probably formed following a large explosion at the end of the last ice age.

The volcano has been named Borealis Mud Volcano, and it is only the second of its kind ever discovered in Norwegian waters.

Powerful eruption rocks Costa Rica's Rincón de la Vieja Volcano

There was no impact on people and infrastructure due to the volcano.
The Rincón de la Vieja volcano, in northern Costa Rica, registered yesterday a "powerful" eruption with no reported effects to people or infrastructure, one month after the last notable eruptive event, authorities reported.

"Today at 14H34 (local time, 20H34 GMT) the Rincón de la Vieja volcano has made a powerful eruption," said in a video Cyrill Müller, volcanologist of the Vulcanological and Seismological Observatory of Costa Rica (Ovsicori) of the National University (UNA).

"The plume composed of water vapor and volcanic material reached a height of 3,000 meters above crater level," he added.

This eruption was "phreatic", and occurs when there is interaction between hot magma and water, which vaporizes and increases 1,000 times its volume in seconds, producing an explosion.

Italy's Mount Etna volcano spewing smoke and ash in new eruption

mmmmmm
Mount Etna, Europe's most active volcano, has started erupting, spewing ash on Catania, eastern Sicily's largest city, and forcing a suspension of flights at that city's airport.

Italy's National Institute of Geophysics and Volcanology, or INGV, which closely monitors Etna with instrumentation on the slopes, noted that cloud cover on a rainy day was impeding views of the eruption, which often serves up a spectacular display of flaming lava during the volcano's not infrequent eruptions.

The institute said that ash had fallen on Catania and at least one town on Mount Etna's inhabited slopes. No injures were reported.

New volcano discovered in the Barents Sea

A unique new volcano has been discovered at 400 meters depth in the Barents Sea. The volcano erupts mud, fluids and gas from the planets interior, giving new insight to Earth science.

Scientists from UiT, The Arctic University of Norway, in partnership with REV Ocean, have discovered the second ever mud volcano found within Norwegian waters. This unusual geological phenomenon was discovered onboard the research vessel Kronprins Haakon with the piloted submersible vehicle ROV Aurora in the Southwestern Barents Sea at the outer part of Bjørnøyrenna (Outer Bear Island Trough). It lies at approximately 70 nautical miles south of Bear Island and at 400m depth.

"Seeing an underwater mud eruption in real time reminded me how "alive" our planet is," says Professor Giuliana Panieri, expedition leader and Principal Investigator of the AKMA project.

The volcano has been named The Borealis Mud Volcano.
