    Ancient rhinos in Nebraska lived in large local herds and died slowly from volcanic ashfall, not sudden disaster. Credit: John Haxby/The University of Nebraska State Museum ************************************************************************* Volcanic eruption from 12 million years ago preserves a snapshot of extinct animal life. Rhinos that once roamed much of North America 12 million years ago likely lived in large herds, according to a new study by the University of Cincinnati. Researchers examined isotopes in the teeth of rhinos found in what is now northeast Nebraska. At this site, more than 100 rhinos died at a single water hole and were buried in...

    This week, an unusually strong earthquake swarm occurred at an Azores volcano which last erupted a little over 300 years ago. Meanwhile, in Japan, the alert level was raised at the Kirishima volcano, suggesting an increased risk that it may soon erupt. And, in Indonesia, it appears that a new batch of magma has intruded underneath the highly potentially dangerous Mount Awu volcano. This video will discuss these stories and list the 47 actively erupting volcanoes around the planet via the analysis of a geologist. This video's thumbnail image displays the erupting Santiaguito lava dome (Santa Maria volcano) in Guatemala....

    Are two of the most dangerous volcanoes in the entire world starting to wake up? We live at a time when seismic activity is on the rise all over the planet. More than three dozen volcanoes have recently erupted, and there have been more than 850 earthquakes in California and Nevada within the past seven days. Unfortunately, most people are not taking the threat that we are facing seriously. (snip) Thankfully, seismologists do not expect Yellowstone to erupt right now. (snip) In the shadow of Mount Vesuvius, a much larger and potentially catastrophic threat looms beneath the ground—Campi Flegrei, the...

    Bronze Age footprints, both from animals and from humans, were initially identified as work was conducted on the Diramazione Nocera-Cava dei Tirreni methane pipeline in the municipalities of Nocera Superiore, Nocera Inferiore, Roccapiemonte, and Castel San Giorgio. This prompted a two-year-long archaeological investigation.SoGEarch, an Italian archaeological society, oversaw the excavations through the Superintendence of Archaeology, Fine Arts and Landscape for the provinces of Salerno and Avellino.The footprints found near the Casarzano stream in Salerno, roughly 20 miles away from Pompeii, contained rock fragments from the eruption of Mount Vesuvius. Experts believe the people who left behind these prints were trying...

    A state of emergency has been declared on the Greek island of Santorini after days of consecutive earthquakes. It comes after a magnitude 5.2 tremor was recorded at 21:09 local time (19:09 GMT) on Wednesday between the Greek islands of Amorgos and Santorini, making it the strongest in recent days. It is estimated to have occurred at a depth of 5km (3.1 miles). The decree will be in effect until 3 March to "address the emergency needs and manage the consequences", officials said. More than 11,000 people have already left Santorini, with around 7,000 departing by ferry and 4,000 by...

    The Debrief ^ | January 30, 2025 | Christopher Plain
    Scientists studying six North American volcanoes situated along the continent’s Cascade Range have found active magma underneath both active and dormant volcanic sites. Previous research has suggested that volcanoes lose significant magma volume when they erupt, and any remaining magma dissipates over time. The scientists behind the discovery argue that a better understanding of the conditions underneath volcanoes could answer several enduring questions about their lifecycles, including whether or not all dormant volcanoes contain pools of magma underneath. The researchers also believe a better understanding of these magma-filled chambers could help inform efforts to prepare for potential volcanic eruptions. Even...

    The first sign of an impending cataclysm in the summer of 1831 was an eerie dimming of the Sun, which for days appeared bluish green across the Northern Hemisphere. In the ensuing weeks, foul weather and a long cold snap triggered crop failures and famines in India and Japan. The instigator was long presumed to be a climate-altering plume from a major eruption, but the volcano’s identity had been one of the great unsolved mysteries of volcanology. “It’s like a whodunit,” says Clive Oppenheimer, a volcanologist at the University of Cambridge. At long last, the culprit has been unmasked in...

    Shortly after the devastating eruption, some gophers went on a very confusing day trip. A member of the gopher recovery team getting to work. Image credit: Mike Allen/UCR When Mount St Helens erupted in 1980, the resulting lava, ash, and debris turned the landscape barren for miles around. It was clear the land would take a long time to recover from the eruption. But one team of scientists had an idea about how they could help speed up the process; sending a few gophers there on a day trip. Plant life struggled to return to the area around Mount St...

    I'm in one of the world's volcanic hotspots, northeast Iceland, near the Krafla volcano. A short distance away I can see the rim of the volcano's crater lake, while to the south steam vents and mud pools bubble away. Krafla has erupted around 30 times in the last 1,000 years, and most recently in the mid-1980s. Bjorn Guðmundsson leads me to a grassy hillside. He is running a team of international scientists who plan to drill into Krafla's magma. “We’re standing on the spot where we are going to drill,” he says. The Krafla Magma Testbed (KMT) intends to advance...

    Should we be concerned by all of the volcanic activity that we are witnessing all over the planet right now? According to Volcano Discovery, 27 different volcanoes are erupting at this moment and many others are showing signs of waking up. Of course, this comes at a time when we are also seeing lots of unusual earthquakes around the globe. I have been regularly warning my readers about the instability of our planet, and it appears that seismic activity is beginning to spike as we approach the end of 2022. So will this trend continue once we get into 2023?...

    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...
