LOS LLANOS DE ARIDANE, Canary Islands (AP) — A river of fresh lava from the volcano on the Spanish island of La Palma threatened on Wednesday to engulf a parish church that has so far survived the eruption that shows no signs of relaxation after 10 weeks. The lava flow closest to Los Llanos de […]
With widespread flooding in the Fraser Valley and critical mountain roads to the rest of the province and Canada cut off by washouts and landslides, November 2021 has been a tough month for British Columbia, but a reminder brutal that this corner of the world is prone to a number of natural disaster risks. Although […]
A team of astronauts, engineers and geologists travel to Spain’s Canary Islands, one of Europe’s volcanic hotspots, to learn how to best explore the Moon and Mars during the Pangea de ESA.

Hotspot volcanoes, those in which magma from mantle plumes reaches the surface, have long been considered clues to mantle mysteries. Spain’s hot volcanoes the Canary Islands, however, are a magmatic mystery in themselves. The magma from these volcanoes can have very different chemical compositions despite being part of the same volcanic system and in some […]

The USGS continues to closely monitor volcanoes around the United States, with four now at Orange / Watch elevated due to noted activity on all four of them. The Great Sitkin, Pavlof, Semisopochnoi and Kilauea are the four volcanoes showing signs of trouble. With the exception of Hawaii’s Mauna Loa, which remains yellow / advisory, […]
The Spanish Costa Brava is rightly coveted for its stunning beaches and beautiful coastline. But visitors to the area should get away from the sands and sangria and add a diversion a short distance inland to their itinerary – to the beautiful La Garrotxa Volcanic Zone Natural Park. It is about an hour’s drive from […]
The incandescent lava spurting from the Cumbre Vieja volcano continues to wreak havoc on the Spanish island of La Palma, destroying buildings and forcing massive evacuations. The volcanic eruption of La Palma which began on September 19 is one of more than 50 in the world that are marked as “continuous” as of October 12, […]
Last week, we discussed the first results of analysis of lunar samples reported by the Chinese Chang’e-5 mission, which revealed that about 10% of these rocks did not come from the landing site of Oceanus Procellarum. This landing site is primarily known to be solidified lava near an ancient volcanic eruption. But while these so-called […]
There is nothing we can do about flank collapses except have a good early warning system. Don’t worry about it â€, the mainstream media are running the risk that the volcanic eruption in La Palma, in the Canary Islands, turns into a mega-tsunami. The media definitely overstated this risk when it was first suggested twenty […]

Cumbre Vieja volcano, located on the Spanish island of La Palma, has been erupting since mid-September. In addition to the destructive lava flows and airport closures, the volcano produced a fascinating cloud formation when it erupted on October 4. On Thursday, La Palma airport was closed for the second time in about two weeks due […]

The volcanoes we see on the Earth’s surface are just the tip of the iceberg. Below the surface, they are fed by a complex network of conduits and reservoirs that bring molten rock, called magma, back to the surface. When the magma erupts, it can generate lava flows that cool down to become volcanic rocks. […]

For hard evidence of nature’s ability to degenerate into catastrophic disaster, look no further than the volcano. These metaphorical portals to hell, which currently number around 1,500 worldwide, not only spew volcanic ash and lava, but can dramatically alter the climate and course of world events. Most are stratovolcanoes, cone-shaped elevations built over time from […]

This Jurassic-like island landscape is one of the most fascinating in the world, and there is plenty to do for interested travelers. Reunion Island is a French island off the coast of Madagascar and is a lush, volcanic tropical paradise that seems straight out of Jurassic Park. Unlike many other legacies of the old empires […]
Volcanoes that have erupted for millennia in a certain way have the capacity to undergo unexpected changes We all know the basics of volcanoes. These are spots on the earth’s crust from which molten rock, volcanic ash and some gases can escape from an underground chamber. Molten rock is called magma when it is below […]

According to the traditions of the Australian Gunditjamara people, the mainland’s Budj Bim volcano formed when a giant crouched on the earth for so long that its body became a volcanic mountain and its teeth turned into lava that the volcano spat out. But as the science of geology explains, the 60 to 80 the […]
In March, a volcano in southwest Iceland, on the Reykjanes peninsula, began to erupt. Thousands of visitors have since been drawn to the Geldinga Valley to watch lava flows from what geologists call a “minor” eruption. “But for Icelanders, it’s a rare opportunity to see their volcanic landscape take shape,” Egill Bjarnason told the Financial […]

This week has seen two major volcanic eruptions, so now is the perfect time to try to understand why these spectacular events are happening. Dr Siobhán Power of Geological Survey of Ireland answers a few questions, but let’s catch up with the news first … Earlier in the week, Etna in Italy exploded. Read the […]
Mountains are formed by movement within the earth’s crust. The crust itself is made up of several large plates, called tectonic plates, which float freely. These huge pieces of the earth’s crust move through molten rock called magma, allowing them to move and collide over time. Even though humans live on the crust, they don’t […]
Venus is our toxic twin. Its chemical composition, size and density are similar to those of our world, although its hellish temperatures can melt lead and its atmosphere is full of sulfuric acid. But it may be even more Earth-like than we knew. A paper published last week in Science Advances demonstrates that Venus could […]
THE VOLCANOES are the geological architects of the Earth. They created over 80 percent of our planet’s surface, laying the foundation that allowed life to thrive. Their explosive force makes mountains as well as craters. Rivers of lava spread across dark landscapes. But as time passes, the elements break down these volcanic rocks, releasing nutrients […]
A supervolcano is classified as a volcano with an eruption magnitude of 8, the largest Volcanic Explosivity Index (VEI) value where the volume of deposits for that eruption is greater than 1,000 cubic kilometers (240 cubic miles) . Supervolcanoes occur when mantle magma rises in the crust and is unable to break through a fissure […]
Based on records of volcanic history, geologists calculate the probability of an eruption in California within the next 30 years at 16%. For comparison, scientists put the 30-year probability of a major Bay Area earthquake along the San Andreas Fault at around 22%.
