BOGOTA, Colombia – Experts say a volcano responsible for causing one of the largest disasters in the Western Hemisphere is showing signs of increased activity, which has forced the Colombian government to issue evacuations in the potential impact zone. The Nevado del Ruiz volcano sits about 80 miles west of Bogotá, and according to Colombia’s Geological Survey, an earthquake swarm has increased to levels not seen since a disastrous eruption in the 1980s killed at least 25,000 people. Authorities have raised the alert level to orange – the second-highest on a four-stage scale. A recent update posted by the Global...

Moscow: A significant volcanic eruption in Kamchatka, a peninsula in far-eastern Russia, has prompted the Federal Agency for Air Transport, Rosaviatsiya, to issue a strong recommendation to aircraft to evaluate their flight paths. Rosaviatsiya said that the Bezymianny volcano, one of the most active in the area and located in the eastern section of the peninsula, erupted on Friday morning with a 12,000-meter column of ash that subsequently began to drift towards the southeast.

The volcano, located in Indonesia’s Yogyakarta special region, erupted at about 12pm (05:00 GMT) on Saturday and unleashed clouds of hot ash and a mixture of rock, lava and gas that travelled up to seven kilometres (4.3 miles) down its slopes. A column of hot clouds rose 100 metres into the air, said the National Disaster Management Agency’s spokesperson Abdul Muhari. There were no immediate reports of casualties. At least eight villages near the volcano have been affected by volcanic ash... Kompas TV showed ash-covered houses and roads at a village near the volcano, located on Java Island. The 2,963...

Part of the adventure in luring your friends out to the high desert terrain in Northern California, where a valley floor spills from the northern backside of Mount Shasta, is that precious moment when they look at you as though you’ve led them into danger. Having discovered Pluto’s Cave from a map, I was prepared for some sagebrush whacking. What I wasn’t prepared for was that reaching the trailhead required navigating a maze of dusty roads. The cave is considered an easy hike — no serious spelunking experience necessary — and located less than 20 minutes from Interstate 5. Pluto’s...

For decades, astronomers assumed that Mars was geodynamically dead — a planet without rumbling earthquakes and erupting volcanoes. Though remnants of towering volcanoes exist on the surface of the Red Planet today, these colossal structures have been dormant for millions of years. With little to no heat firing the planet's engine, scientists reasoned, Mars became dormant long ago. However, over the last five years, this assumption has been proven wrong. NASA's InSight mission has detected quakes and even evidence of recent volcanism around one Martian region, known as Elysium Planitia. And now, they think they know why this activity is...

deepest hole ever drilled, the Kola Deep borehole in the Russian Arctic, reaches only 0.2 percent the way to the center...even the best scientific maps didn’t look much better than your middle-school textbook cartoon showing an outer crust, an inner core and a thick layer called the mantle in between But that picture is changing. Researchers... are...seeing is full of complex detail...The mantle appears to be layered like an onion, with major transitions 250 miles and 410 miles down. At the 410-mile level, researchers recently identified a tremendous interior mountain range, with peaks perhaps even taller than Mount Everest. “...

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?...

Marine archaeologists have located a "unique" ancient temple lost beneath the seabed close to the site of what has been dubbed the "Las Vegas" of the Roman Empire.The temple, thought to date to around 2,000 years ago, is positioned on the opposite side of the Gulf of Pozzuoli to Rome's "Sin City."This ancient city, known as Baiae, was the playground of the Roman elite in its heyday. A fashionable coastal resort, Rome's rich and powerful built luxurious villas at the site—including the emperors Julius Caesar, Nero, and Hadrian—attracted by its beautiful setting and healing natural hot springs, not to mention...

Pele’s Hair, a byproduct of volcano eruptions, are thin glass fibers “named after the volcanic deity Pele,” according to the National Park Service. Piles of the long, hair-like fibers can be found near volcanic summits in Hawaii. The fibers resemble “golden mats of hair,” the park service says on a page about the phenomena. Strands of Pele’s Hair can stretch up to 2 feet in length but are less than a micron, or .001 millimeters, wide. They are light enough to be picked up and carried by the wind. Pele’s Hair can form mats up to several inches deep. The...

The world's largest active volcano has erupted in Hawaii for the first time in nearly four decades, officials said. Mauna Loa erupted at 11:30 p.m. local time Sunday (4:30 a.m. ET Monday), the U.S. Geological Survey said. It was the first eruption since 1984, according to its Hawaii Volcano Observatory daily update. The eruption began in Moku‘āweoweo, the summit caldera of Mauna Loa, inside Hawaii Volcanoes National Park, the agency said, as it upgraded the volcano's alert level from an "advisory" to a "warning." "At this time, lava flows are contained within the summit area and are not threatening downslope...

...Last spring, Manning realized he could solve the problem by looking elsewhere -- hundreds of kilometers away from Thera -- to regions of the Aegean Sea that experienced the tsunami effects caused by the eruption. Manning incorporated dates obtained for these episodes into his model to test for, and discount, the volcanic carbon dioxide caveat. On Thera itself, he also spotted the importance of a short but clearly observed gap in time between the abandonment of the town at Akrotiri and the huge eruption, and he incorporated this previously overlooked constraint into the modeling....

The powerful earthquake that hit Indonesia was just the latest display of violent seismic activity on the archipelago, which stretches across one of the most unstable parts of the Earth's surface. The country's position on the planet's crust means it will continue to experience such catastrophes, just as it has done for the past 50 million years or so, according to seismologists. "The problem with Indonesia is that you have an area of intense seismic activity coinciding with a very densely populated part of the world," said Gary Gibson, professor of seismology at the RMIT University in Melbourne, Australia. "It...

Photos taken by astronauts on the International Space Station show a giant black streak created by a lava flow thousands of years ago. The photos, taken in June but not released until late September, have been put together by NASA in order to create a larger photo showcasing the streak in its entirety. In total, the streak, located in New Mexico, measures 50 miles (75 kilometers) in length across the Chihuahuan Desert, according to the NASA Earth Observatory.

Recent Icelandic rifting events have illuminated the roles of centralized crustal magma reservoirs and lateral magma transport, important characteristics of mid-ocean ridge magmatism. A consequence of such shallow crustal processing of magmas is the overprinting of signatures that trace the origin, evolution and transport of melts in the uppermost mantle and lowermost crust. Here we present unique insights into processes occurring in this zone from integrated petrologic and geochemical studies of the 2021 Fagradalsfjall eruption on the Reykjanes Peninsula in Iceland. Geochemical analyses of basalts erupted during the first 50 days of the eruption, combined with associated gas emissions, reveal...

The initial tsunami wave created by the eruption of the underwater Hunga Tonga Ha'apai volcano in Tonga in January 2022 reached 90 meters in height, around nine times taller than that from the highly destructive 2011 Japan tsunami, new research has found. An international research team says the eruption should serve as a wake-up call for international groups looking to protect people from similar events in future, claiming that detection and monitoring systems for volcano-based tsunamis are '30 years behind' comparable tools used to detect earthquake-based events. Dr. Mohammad Heidarzadeh, Secretary-General of the International Tsunami Commission and a senior lecturer...

A young Brit has died in a tragic accident at the "volcano from hell" in Ecuador. Gil Banks, 25, was attempting to climb up the Rucu Pichincha volcano near Quito on Sunday, August 14, when he fell to his death. Banks was originally born in London and grew up in Newton Mearns before he emigrated with his family to Israel, Glasgow Live reported. He leaves behind his Glaswegian father and English mother following the sad accident. His horror death was confirmed by the Israeli Embassy in Ecuador. The Times of Israel reported Banks had recently finished serving in an elite...

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...

Here is the late info on the Hunga Tonga volcano

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...
