Japan’s Mount Sakurajima volcano makes largest eruption in 3 years

Japan’s Mount Sakurajima volcano makes largest eruption in 3 years

World
Nov. 8 (UPI) -- Japan's Mount Sakurajima volcano erupted again Friday -- only this time sending out its largest plume in three years, officials said. The eruption ejected smoke and debris more than 3 miles into the air, the Japan Meteorological Agency said. The explosions in the mountain's Minamidake crater, at 3,412 feet in elevation, darkened skies over Kyushu island in southwest Japan and formed the largest ash cloud since 2016. Kagoshima Prefecture officials said there were no immediate reports of damage or injuries. "Explosive activity continues," the weather agency's Volcanic Ash Advisory Center warned on Thursday. It referred to an ash plume that rose to 7,000 feet, threatening planes flying nearby. Pulverized rock in volcanic ash can get stuck inside jet engines and stall airline...
Anak Krakatau volcano collapse: ‘Warning signs were there’

Anak Krakatau volcano collapse: ‘Warning signs were there’

Science
Anak Krakatau, the Indonesian island volcano that collapsed last December triggering a huge tsunami, did produce clear warning signals before the event.That's the assessment of a German-led team which has reviewed all the data.The scientists say satellites in the months leading up to the catastrophe had observed increased temperatures and ground movement on the volcano.Earthquake and infrasound activity was also detected two minutes prior to the collapse of Anak's southwestern flank.When this mass slid into the sea, it sent a wall of water, up to 4m high, around the Sunda Strait.More than 400 people died in the 22 December tragedy; a further 7,000 were injured and nearly 47,000 were displaced from their homes. ...
Scientists consider ‘human-made volcano’ to slow global warming

Scientists consider ‘human-made volcano’ to slow global warming

Science
Aug. 5 (UPI) -- Throughout Earth's history, volcanic eruptions have periodically cooled Earth. Though most eruptions aren't big enough to influence global climate patterns, especially large eruptions can have a global impact. When a large amount of ash is spewed into the atmosphere, the particles reflect the sun's rays back toward space, lowering the temperature on Earth. In a new paper, published this week in the journal Geophysical Research Letters, scientists considered the possibility of replicating the cooling effects of a volcanic eruption -- a "human-made volcano" to combat climate change. "Nobody likes the idea of intentionally tinkering with our climate system at global scale," Ken Caldeira, researcher at the Carnegie Institution for Science, said in a news release. "Even if we ...

Etna volcano wakes up in Italy producing quakes, column of ash

Etna volcano wakes up in Italy producing quakes, column of ash

Science
Dec. 24 (UPI) -- The Mount Etna volcano, the highest in activity in Europe and one of the most active in the world, woke up Monday morning producing intense seismic activity and producing a cloud of ash visible from several miles away. The activity started at 8:50 a.m. local time and just in the first three hours there were nearly 130 earthquakes, according to a statement from the Italian Institute of Geophysics and Vulcanology. The earthquakes were accompanied by the emission of a dark cloud of ash, it added. Authorities have issued a yellow alert but are monitoring the activity, Italian newspaper Il Corriere della Sera reported. The nearby airport of Catania functioned throughout the day without problems other than one hour of flight interruptions, during the afternoon, the newspaper re...
