A hiker takes video of the lava flows on March 25. VOLCANO ERUPTION 2021 There is a volcanic eruption in Iceland every 4-6 years on average. “I think a couple of their boots also melted.”. As is typical for this sort of eruption, both on Earth and on Mars, a second fissure—perhaps one of many to come—opened up just north of the first on April 5, creating its own fountains and rivers of lava. There, they would have been periodically cooked by sterilizing lava flows, which is exactly what’s happening at Geldingadalur today. Magma may be profoundly lethal to humans, but the microbes under Geldingadalur are “probably loving it,” Moreras Marti says. But perhaps most important, the researchers will be able to trace the evolution of underground ecologies from the very moment a new habitat appears. April 6, 2021. Yet little is concretely understood about the origins, evolution, and behavior of Mars’s volcanism, which is one reason why researchers are excited to use the Geldingadalur eruption as an analogue. A recent volcanic eruption has people flocking to see it in Iceland — and some have even gotten close enough to roast hot dogs on it. This pint-size paroxysm was made possible by the peninsula’s location: It sits atop the Mid-Atlantic Ridge, the volcanic rift that pushes the Americas away from Europe and Africa. The eruption of a fissure near Mount Fagradalsfjall, which began late Friday, was the first in the same volcanic system in about 900 years.. On March 19, lava roared out of the ground in the uninhabited valley of Geldingadalur, marking the first time in 800 years that this strip of land has been rocked by an eruption. Mars is an unquestionably volcanic planet. Martian eruptions often involved an exceedingly fluid version of basalt, suggesting that its volcanoes may sometimes have had Icelandic-style plumbing. Read: What happens if a ‘big one’ strikes during the pandemic? It may even be volcanically active today, with magma still gurgling below ground, perhaps gearing up for a future eruption. It’s a Martian eruption in miniature. Published April 16, 2021. If so, this site will become a draw for planetary scientists and astrobiologists alike: a long-lived, safe and easily accessible natural laboratory in which to better understand two planets for the price of one eruption. Hikers make their way to and from the site on March 28. (Samples may need to be taken from people’s boots too, Hamilton says, to try and spot any stowaways—a distinctly earthly, not Martian, issue. — Katrín Jakobsdóttir (@katrinjak) March 19, 2021 The Fagradals Mountain volcano had been dormant for 6,000 years, and the Reykjanes Peninsula hadn't seen an eruption of any volcano in … The Geldingadalur eruption also began along a fissure. Conversely, it could continue for years, perhaps decades, much like the 35-year Pu‘u ‘Ō‘ō eruption on the flanks of Hawaii’s Kīlauea volcano. The … Being shielded from the deadly radiation bombarding its surface, these subsurface hideaways would be relatively habitable environments. Tweet. There is one crucial difference, however: the scale of the events. Located between the second and third eruption site, the new fissure vent started to erupt another basaltic lava flow. Emily Buder/Quanta Magazine. It followed thousands of small earthquakes in recent weeks and was the first on the peninsula since the 12th century. The new volcanic fissures are more otherworldly than they first appear. The reason for the volcano activities is that the country is located on the Mid Atlantic Ridge, the one that separates the North American and Eurasian tectonic plates. Basalt is common to plenty of volcanoes, but the Geldingadalur eruption’s basaltic magma has an especially runny consistency; it’s coming up straight from the mantle and speeding right through the crust. An eruption could be imminent ... 2021 shows the lighthouse and the geothermal energy plant near … Updated 1834 GMT (0234 HKT) April 6, 2021. The last eruption is actually still ongoing at the time of writing this article and began on March 19, 2021. A person watches the volcano on March 29. If the conduit to the magma below remains open, the Geldingadalur eruption could end up building a small shield volcano, an extremely broad magmatic mound with a very low-angle slope. It came after weeks of increased seismic activity on the peninsula, with tens of thousands of earthquakes disturbing the magma underground. As in 2014, this is also a more peaceful lava flow eruption, occurring in the Fagradalsfjall volcanic … Mars’s lava flows were jaw-droppingly prolific, many with enough lava to bury a landmass the size of the U.K. in a matter of weeks. The lava is killing off preexisting microbial life in the soil. The eruption came after weeks of increased seismic activity on the peninsula. Mere weeks after Iceland’s Eyjafjallajökull eruption in 2010, scientists found not only that microbes had colonized the surrounding soil, but that they were living on the new lava flows themselves. And in places where the crust split, Martian magma erupted out of fissures. Mount Fagradalsfjall – a volcano on Iceland’s Reykjanes peninsula – began to erupt on the evening of March 19, 2021, the Icelandic Meteorological Office reported. In its earliest eras, it built volcanoes so immense that their formation deformed its surface. Humanitarian Crisis Unfolding On St. Vincent After Volcano Eruption A volcano erupted last week on the Caribbean island of St. Vincent, and the volcano is still active. “Iceland is an incredible place and one of the best analogues for Mars we have on Earth,” says Arola Moreras Marti, a researcher at the University of St. Andrews. But perhaps the most exciting correlation between Mars and Iceland is how their volcanic activity may influence biology. Compared to other volcanic eruptions in Iceland, Geldingadalsgos can be considered quite small – the fissure is only about 500-700 meters long. Read Later. These sorts of compounds are also being transported around Geldingadalur’s soggy subsurface, setting up chemical imbalances that microbes thrive on. The eruption of a fissure near Mount Fagradalsfjall, which began late on Friday, was the first in the Krysuvik volcanic … That makes the subsurface shenanigans at Geldingadalur a rare and nearly ideal biological simulacrum of what may have once happened, or may still be happening, on Mars. The volcano erupted nine days earlier. Such an edifice would be comparable to those found all over Mars, Hamilton says, which means this eruption could allow scientists to watch one grow on Earth in real time. A Quarter Of The Population Have Visited The Volcanic Eruption. The eruption of a long-dormant volcano that sent streams of lava flowing across a small valley in southwestern Iceland is easing and shouldn't interfere with air travel, the Icelandic Meteorological Office said Saturday. A few weeks ago we shared these dramatic photographs of Iceland’s Fagradalsfjall volcano as spews molten rock into the air, and a new short film by French director Stéphane Ridard hovers over the Geldingadalur landform to capture the eruption, which is the first in 6,000 years, in incredible detail. Iceland, Volcano. This is a close-up shot of hardened lava at the site. Mars was also considerably wetter when it was young, with a thicker radiation-blocking atmosphere. Volcano Country Eruption Start Date Eruption Stop Date Max VEI WVAR; Veniaminof: United States: 2021 Feb 28: 2021 Mar 12 (continuing) – Yes: Raung: Indonesia: 2021 Jan 21: 2021 Mar 12 (continuing) – Yes: Merapi: Indonesia: 2020 Dec 31: 2021 Mar 12 (continuing) – Yes: Soufriere St. Vincent: Saint Vincent and the Grenadines: 2020 Dec 27: 2021 Mar 12 (continuing) – Yes: Kilauea Hikers gather to watch the volcano on March 21. On March 19, lava roared out of the ground in the uninhabited valley of Geldingadalur, marking the first time in 800 years that this strip of land has been rocked by … “As soon as we saw the first earthquake swarms, we basically went out sampling all of the different areas to get an idea of what the baseline microbial ecology would be,” he says. The eruption produced a … Hamilton and others will continue to take microbial samples from the soil and also from the air, as invading microbes may prefer gliding as opposed to swimming. Art Bicnick. The eruption could fizzle out in the coming days or weeks. Lava has been bubbling out of an oddly shaped cone, slowly filling up the valley. ), Scientists will also sample the lava itself. There is no explosive activity, no ash fall and limited lava flow. Photos of Iceland’s Fagradalsfjall Volcano, Up Close With Iceland’s Fagradalsfjall Volcano. Scientists are using the current eruptions in Iceland to understand the possible history of life on Mars. Swarms of small earthquakes in February 2021 on Iceland’s Reykjanes peninsula had experts warning that magma was moving beneath Geldingadalur valley and could soon erupt. This happened all the time in Mars’s past—it may even be happening now—when magma cooked rocks and released hydrogen, carbon dioxide, methane, iron, sulfates, and other compounds that microbes can use to sustain themselves. Volcanic tremor has appeared recently as well, indicating that magma movements underneath are likely accompanying and/or causing the seismic swarm. A hiker walks past the volcano on March 26. A strong seismic crisis has been occurring on the Reykjanes peninsula near Fagradalsfjall mountain since mid Feb 2021, involving several magnitude 5+ and thousands of smaller ones. REYKJAVIK, Iceland (AP) — The eruption of a long-dormant volcano that sent streams of lava flowing across a small valley in southwestern Iceland is … A volcano just 40 kilometers from Iceland's city of Reykjavik, has been drawing crowds keen to witness it erupting after 900 years of inactivity.

As we speak, there is a volcanic eruption taking place in Fagradalsfjall, Iceland. REYKJAVIK, Iceland -- A long-dormant volcano on the Reykjanes Peninsula in southwestern Iceland flared to life Friday night, spilling lava down two sides in … A volcano erupting on the island is a living replica of what once happened on Mars. And if you’re interested in what happens when magma meets ice, Iceland is the place to be. Crowds of people have been flocking to the site to witness the lava flows. Golli/Iceland Review/EPA-EFE/Shutterstock. Late on March 19, an eruption officially began as lava broke through the surface near Fagradalsfjall, one of several shield volcanoes on the peninsula. Lava spews out of a volcano on Iceland's Reykjanes peninsula on March 28. That makes the Geldingadalur eruption a “model-scale lava field,” says Tobias Dürig, a volcanologist at the University of Iceland. People walk near the volcano on March 21. A recent volcanic eruption has people flocking to see it in Iceland — and some have even gotten close enough to roast hot dogs on it. Mezeul II said he was able to make the Iceland trip because the country has its borders open to vaccinated United States citizens. Words by. “The lava was still hot,” says Mario Toubes-Rodrigo, a microbiologist at the Open University, in the United Kingdom, who explained that the visiting scientists had to be extremely careful. “It formed, and then it had places to go and things to do.”. It “didn’t really stall too much on its way to the surface,” says Tracy Gregg, a planetary volcanologist at the University at Buffalo. AP Magma inside these volcanoes powers hot hydrothermal pools at the surface, where Moreras Marti goes looking for microbial life.
