Europe's mysterious "Little Ice Age" has been traced back to a massive volcanic eruption in Indonesia - thanks to Pink Floyd. It lasted centuries and led to the Thames Frost fairs, when the river froze over for months at a time - turning it into a skating rink. A generally warm medieval period was followed by a mostly cold spell - from the 14th to the 19th Centuries. The weather phenomenon has baffled climatologists for decades. A study - inspired by the 70s rock legends' Dark Side of the Moon - now shows it was triggered by a catastrophic eruption...

The Hayli Gubbi volcano in Ethiopia, located about 500 miles from the capital city of Addis Ababa, erupted on Sunday for the first time in about 12,000 years. The eruption was not too devastating as such events go, but it did release an enormous plume of ash, which rode the subtropical jet stream and quickly expanded to cover parts of Yemen, Oman, India, and Pakistan. Air India announced it canceled at least 11 flights on Tuesday due to concerns over the cloud. “The affected altitude is between 8.5 kilometers (5.2 miles) and 15 kilometers above the sea level,” said Mrutyunjay...

A volcano in Ethiopia erupted for the first time in at least 12,000 years on Sunday, sending a cloud of ash and smoke northeast across the Red Sea. Hayli Gubbi, a volcano in the Afar region of northern Ethiopia, erupted at around 8:30 a.m. UTC (3:30 a.m. EST) on Nov. 23. By 8 p.m. UTC (3 p.m. EST), the explosive phase of the eruption had stopped, according to the Toulouse Volcanic Ash Advisory Center (VAAC) in France. This is the first time Hayli Gubbi is known to have erupted in the Holocene — the present geological epoch that began at...

A major explosive volcanic eruption unexpectedly began this morning at Ethiopia's Hayli Gubbi volcano, leading to the generation of an ash cloud the size of Portugal. Lengthy pyroclastic flows were generated, and heavy ashfall has occurred. Today's video discusses the ongoing eruption via the knowledge and analysis of a geologist.

A massive dry fracture has just opened on Mount Etna -- and scientists are now raising the alert level. This newly discovered fissure on the southeast wall is not releasing lava, but that doesn't make it safe. In fact, this type of "silent cracking" is often a sign of deep internal pressure, structural movement, or early-stage volcanic instability. In today's Geology Watch report, we break down the footage shared by Pio Andrea Peri and the latest update from INGV, which has now issued an F1 Alert Status -- indicating a high probability of lava fountains and increased volcanic activity at...

Flights serving the eastern Sicilian city of Catania were halted on Monday after an eruption from nearby Mount Etna, local authorities said, bringing fresh travel woe to the crisis-plagued Italian airport. The 3,330 metre (10,925 ft) high volcano burst into action overnight, firing lava and ash high over the Mediterranean island. The lava flow subsided before dawn, but ash was still coming from one of the craters. Flights to and from Catania, a popular tourist destination, would be suspended until 8:00 p.m. (1800 GMT), the airport said on Twitter. Catania Mayor Enrico Trantino banned the use of motorcycles and bicycles...

MOUNT Etna has erupted sparking fear across Sicily as Europe's biggest and most powerful volcano sends an ash cloud across the holiday isle in Italy. Italy’s Mount Etna has started spewing lava in what is its second eruption of the year. Giant fountains of lava could be seen sprouting from the volcano, located on the isle of Sicily, as far away as Catania, around 30 kilometres away, and the resort town of Taormina.

A mantle plume producing almost as much heat as Yellowstone supervolcano appears to be melting part of West Antarctica from beneath. Researchers at NASA have discovered a huge upwelling of hot rock under Marie Byrd Land, which lies between the Ross Ice Shelf and the Ross Sea, is creating vast lakes and rivers under the ice sheet. The presence of a huge mantle plume could explain why the region is so unstable today, and why it collapsed so quickly at the end of the last Ice Age, 11,000 years ago.

Mount Fuji is the tallest peak in Japan, with a height of 3,776 meters (12,388 feet). Image credit: Tomáš Malík/Shutterstock.com The Tokyo Metropolitan Government has released a video containing AI-generated imagery to warn what would happen if Mount Fuji erupted in the 21st century. While there’s no suggestion the volcano is set to blow any time soon, an eruption within the next century would not be totally unexpected – and the impact on Tokyo would be significant. The video (below) was released by Japanese local authorities on August 22, 2025, as part of the newly designated Volcano Disaster Preparedness Day,...

For centuries, the waterfront resort of Baiae on the Bay of Naples was the stomping ground of Rome's rich and famous. Located around 150 miles south of the capital, many of Rome's wealthiest citizens, including several emperors, built villas there to escape the scorching city heat and take in the area's sulfurous waters. However, most of the site today lies submerged beneath the sea and is preserved as a spectacular underwater archaeological park, as seismic and volcanic activity has caused the coastline to sink as much as 30 feet. Recently, according to a report by Finestre sull'Arte, a team of...

HONOLULU (AP) — Hawaii's Kilauea volcano resumed erupting Friday by shooting an arc of lava 100 feet (30 meters) into the air and across a section of its summit crater floor. It was Kilauea's 31st display of molten rock since December, an appropriately high frequency for one of the world's most active volcanoes.

A new global study reveals that ancient carbon, once thought securely stored in soils and rocks, is leaking into the atmosphere via rivers. For the first time, researchers have confirmed that carbon trapped in landscapes for thousands of years or longer can return to the atmosphere as carbon dioxide escaping from river surfaces. The study, led by scientists from the University of Bristol and featured as the cover story in Nature, suggests that plants and upper soil layers may be absorbing about one additional gigaton of CO2 annually to balance this release. This highlights an even more critical role for...

A violent eruption under Greenland’s ice exposed a secret lake and left a crater the size of a city. Credit: ESA | The Daily Galaxy --Great Discoveries Channel A hidden lake beneath Greenland’s Harder Glacier unexpectedly erupted, unleashing a powerful surge of water that carved a massive crater in the ice. The dramatic event caught researchers off guard, as water surged upward through thick ice, creating a profound impact on the glacier. Over just ten days, the lake released 23.8 billion gallons (90 million cubic meters) of water, equivalent to nine hours of Niagara Falls’ full-force flow. A Violent Flood...

A powerful earthquake that struck off Russia's Kamchatka Peninsula on July 29 has triggered a chain reaction of volcanic eruptions along the Pacific Ring of Fire. The 8.8 magnitude quake, followed by multiple aftershocks as strong as magnitude 6, appears to have reawakened long-dormant giants. Klyuchevskaya Sopka erupted a day after the seismic event for the first time in 600 years. Several other volcanoes, Shiveluch, Bezymianny, Karymsky and Avachinsky, have also roared back to life after roughly 300 years of dormancy. Meanwhile, scientists have detected a thermal anomaly at Mutnovsky, indicating rising heat and suggesting an eruption may be imminent....

Google has for years been harnessing the power of its Android smartphones to detect and measure tens of thousands of earthquakes. In a new paper published in the journal Science, researchers from the search giant described how they used motion sensors from its two billion-strong network of phones running Android between the years 2021 and 2024 to detect and alert quakes to users in almost 100 countries around the world. Known as "Android Earthquake Alerts" (AEA), this early warning system has uses the smartphones' accelerometers to detect telltale vibrations as they happen and inform residents of quakes in their areas....
