‘Dukono erupts every second’: Local guides warn of risks on volcano hike

‘Dukono erupts every second’: Local guides warn of risks on volcano hike

Published by Sam Flores

Volcanologists CNA spoke to said Mount Dukono has highly intense eruptive activity. It erupts every day, though eruptions generally occur in the crater area. Since 2008, eruptions plumes have ranged from 50m to as high as 10km. “However, under certain conditions when pressure increases, larger explosive eruptions can occur, such as today,” said Heruningtyas Desi Purnamasari, head of the volcano team at the geological agency in Indonesia’s Ministry of Energy and Mineral Resources. “Today’s eruption reached a height of 10km, with incandescent material projected up to an estimated distance of 2km to 3km”. Mount Dukono has been at Level II (Alert) in Indonesia’s four-tier alert system since 2008. Mount Ibu, also on Halmahera island, is at Level II, while Mount Semeru, the highest volcano on Java and which can erupt every five minutes, is at Level III. Level IV indicates the highest level of volcanic activity. “If asked whether it can be predicted, Mount Dukono does erupt every day. Its activity has been considered elevated or abnormal since 2008,” Heruningtyas said. “Our recommendation at Level …

My helicopter went into freefall – inside an active volcano | Helicopter crashes

My helicopter went into freefall – inside an active volcano | Helicopter crashes

Published by Sam Flores

The 1993 erotic thriller Sliver should have ended differently: Zeke, played by William Baldwin, was scripted to fly a helicopter towards an active volcano, after Sharon Stone’s character, Carly, reveals she’s the killer. The pilot, Craig Hosking, had been tasked with flying low over Hawaii’s Kīlauea volcano, accompanied by the director of photography, Mike Benson, and his assistant Christopher Duddy, to film the bubbling lava and white plumes of smoke escaping from the Puʻu ʻŌʻō vent. It was a clear day on the Big Island when Duddy watched a corkscrew trail form in the smoke behind the helicopter, and he remembers thinking: “I can’t believe I’m getting paid to do this.” It was November 1992, and a big storm was due to hit the area, so they were shooting as much footage as they could along the coast, capturing the rainforest and brilliant blue ocean shimmering against the black lava of the volcano, before the weather disrupted production. But as they dipped over Puʻu ʻŌʻō for a second time, the helicopter’s engine failed. Their visibility …

Central and South America collided much earlier than previously thought

Central and South America collided much earlier than previously thought

Published by Jenni Sidey

The ground beneath northern South America holds memories far older than any city or road. Locked inside ancient volcanic rocks is a record of when continents collided, mountains rose, and the shape of the Americas began to change. A new scientific study suggests that one of the most important tectonic events in this region happened earlier than scientists once believed. Research shows that the collision between Central America and South America was largely complete before about 10 million years ago. That timing challenges long-standing ideas about how and when the northern Andes were formed. The study was led by Victor Piedrahita and J. Li, working with an international team of geoscientists. Their work focuses on Colombia’s Northern Andes, where layers of volcanic rock act like a geological diary. By reading those layers in a new way, the researchers uncovered evidence that major crustal deformation had already slowed by the late Miocene. Geological framework of the northwestern Andes, including major tectonic plates, faults, and cordilleras. (CREDIT: Earth and Planetary Physics) Reading the Past Written in Rock …

Ancient Ocean Volcanoes Linked to Repeated Triassic Extinctions

Ancient Ocean Volcanoes Linked to Repeated Triassic Extinctions

Published by Jenni Sidey

Mass extinction events throughout Earth’s history are characterized as significant disruptions to life on the planet. There have been five major extinction events that have fundamentally changed how life exists on Earth; however, many smaller but equally significant extinction events also occurred. The primary focus of scientists regarding mass extinction events has been on identifying what caused the five major extinction events. There has not been nearly as much work done to determine what caused the many lower-level extinction events that occurred repeatedly, especially during the Triassic Period, when life experienced repeated failures to recover. Research conducted by Jian-Jun Fan and his co-authors from the College of Earth Sciences at Jilin University, provides insight into the mystery of what triggered these lower-level extinctions. They studied volcanic deposits formed along the Tibetan Plateau, a region that was once part of a large ocean. Their findings, published last month in the journal Geology, provide evidence that repeated volcanic eruptions at the ocean floor were responsible for causing at least four extinction events in marine organisms during the …

Black hole space volcano erupts after 100 million year nap

Black hole space volcano erupts after 100 million year nap

Get the Popular Science daily newsletter💡 Breakthroughs, discoveries, and DIY tips sent six days a week. A supermassive black hole is reawakening inside a distant galaxy cluster—and after almost 100 million years of slumber, astronomers now say it’s making up for lost time. According to a study published today in Monthly Notices of the Royal Astronomical Society, J1007+3540 is erupting like a volcano and spewing plasma across interstellar space. A black hole isn’t constantly devouring its unfortunate galactic neighbors. In fact, it can lay dormant for eons. But when one of these gargantuan entities finally reawakens, the resulting display isn’t only impressive—it illustrates the chaotic battle between its own cosmic forces and the pressures of the universe around it. One of the most striking glimpses of such an event was recently captured by a team led by Shobha Kumari at India’s Midnapore City College. Supermassive black holes rarely emit magnetized, radio-emitting plasma, but according to Kumari, J1007+3540 is especially unique. After analyzing data collected by the Low Frequency Array (LOFAR) in the Netherlands and India’s …

Russian volcano spews ash miles into the air as major eruption begins | World | News

Russian volcano spews ash miles into the air as major eruption begins | World | News

Published by Sam Flores

A new volcano eruption shook Russia today. The Bezymyanny volcano in Kamchatka, a peninsula in the country’s far eastern area, threw a column of ash over three miles into the air, local media reports. The huge ash plume extends a whopping 33.5 miles northeast, according to scientists. This could disrupt air travel in and around the surrounding areas. A orange aviation hazard code is now in force, only yesterday scientists warned of a possible explosive eruption. Bezymyanny, which had been considered extinct until 1955, last erupted on April 7 2023, with strong explosive activity and an ash plume rising to around 7.4 miles. At its peak, the ash cloud was visible over a wide area, with satellite images showing it extending hundreds of kilometers. Explosions were loud enough to be heard up to 12 miles away, and the sounds persisted for around 90 minutes. The volcano is a lava-dome stratovolcano, this means its eruptive behavior often involves the growth of a dome, followed by collapse of hot dome material, which can trigger a explosive ash-producing …
