Geldingadalur Volcano, Iceland

[thepastisalreadywritten]

For centuries, the country’s western volcanic peninsula has been dormant, but a new era of volcanic activity could be on the horizon.

The Fagradalsfjall Volcano, a raised crater of bubbling lava — glowing bright yellow in an expanse of dark gray — is the latest eruption heralding Iceland’s new period of volcanic activity.

The eruption announced its approach on July 4 of this year, when southwest Iceland was rocked by more than 2,000 earthquakes in just 24 hours.

Not long after, seismic activity dropped off as magma rose to shallow depths and ultimately gave way to oozing molten rock on July 10.

Located next to the small mountain of Litli-Hrútur, this eruption is taking place on Reykjanes, a volcanically active peninsula that has become a popular destination among tourists looking to see lava fountaining above and pouring onto the surface.

However, the site of the new eruption is potentially hazardous — new fissures may open nearby without warning, rivers of lava can form at a quick pace, and toxic gas can quickly fill the air, according to the Iceland Met Office.

This eruption is the peninsula’s third volcanic paroxysm in a row, following on from similar lava-spewing eruptions in 2021 and 2022 — and it’s unlikely to be the last.

After an eruption last summer, Dave McGarvie, a volcanologist at Lancaster University, told National Geographic that the recent uptick in volcanic activity, “... could herald the start of decades of occasional eruptions.”

Iceland’s volcanic geology

The Reykjanes Peninsula lies about 17 miles southwest of Iceland’s capital city Reykjavik.

It sits atop the continually spreading Mid-Atlantic Ridge, where the North American plate to the west and the Eurasian plate to the east are gradually pulling apart.

Superhot, gassy magma, which is less dense than the surrounding rock, can sometimes rise into the shallow crust from buoyancy alone, but all that regional stretching also creates cracks where molten rock can infiltrate.

The peninsula’s subterranean bedlam seems to manifest as periodic busts of volcanism.

Historical accounts and studies of ancient volcanic rocks show that times of volcanic repose transition into loud seismic and eruptive awakenings in a cycle that’s transpired several times in the past few millennia.

Although the region had been volcanically dormant for centuries, the tectonic sundering happening in the depths meant that the latest eruptions have long been in the works.

A fiery new beginning

And in recent years, several sheets of magma ascended toward the surface, indicated by the changing shape of the ground and swarms of earthquakes, says Tobias Dürig, a volcanologist at the University of Iceland.

But for some time, these magmatic serpents failed to see sunlight — their escape was stymied either from the loss of their own upward momentum or because the resilient crust didn’t offer an escape hatch.

Nevertheless, as earthquakes began to crescendo in both frequency and strength from late 2019 onwards, scientists suspected that an eruption sometime in the future seemed inevitable.

That was confirmed in dramatic fashion on 19 March 2021, when lava began gushing from a 1,650-foot-long fissure in a valley of the Geldingadalur region.

These ferocious fires are gifting scientists with an unparalleled look at the connective tissue between the igneous abyss below and the lava-licked landscape above.

Their efforts help improve our understanding of Earth’s viscera, of Iceland’s volcanic cadence, and of this peninsula’s volcanic dangers.

People advised against volcano path today

The Geldingadalir volcanic eruption site was quiet last night, according to police officer Guðmundur Eyjólfsson. People started arriving early this morning to hike to the volcano, but the wind today is expected to blow gases over the new hiking trail.

Yesterday I took a trip to the ongoing volcanic eruption in Geldingadalur, and we stuck around for a while, from daylight to dark. It was pretty fascinating!

L’éruption du volcan Geldingadalur : La "vallée des castrés" (Geldingadalur) se transforme petit à petit en "champ de lave des castrés" (Geldingahraun). La lave sort au rythme estimé de 5 m3/s, de quoi remplir la vallée en moins de 15 jours. Le débordement se fera ensuite vers le "pâturage de nuit" (Nátthagi). La route vers l'océan sera ensuite encore très longue et il faudrait de nombreux mois d'activité avant que cela se produise.

Spaceweather.com Time Machine - March 25, 2021

CME IMPACT: A CME hit Earth's magnetic field on March 24th (20:16 UT). The glancing blow sparked a G1-class geomagnetic storm and caused electrical currents to flow through the soil of Norway. Arctic skies were mostly cloudy, but some auroras shone through anyway. The storm is subsiding now. Aurora alerts: SMS Text AURORAS OVER AN ERUPTING VOLCANO: The last time a volcano erupted on Iceland's Reykjanes peninsula was almost 800 years ago. So consider this a 1-in-800-year shot: "On March 24th, I photographed the Geldingadalur volcano with auroras dancing overhead," reports Christopher Mathews.

Breaking 8 centuries of quiet, the volcano erupted last week on March 19th. Lava oozing through the ground was bright enough to see from Earth orbit as incandescent fountains illuminated the dark landscape.

Mathews immediately began planning his photo shoot. "The night the Geldingadalur volcano erupted, I began scouting locations for this shot," he says. "There were good auroras over the weekend, but cloud cover blocked them--a huge disappointment. Last night an unexpected snow squall appeared, blotting out the sky and even the eruption itself--another heart-breaker. But then, around midnight, the skies cleared and auroras promptly lit off over the volcano."

We won't have to wait 800 years for the next shot. Historical accounts and ancient lava flows show that whenever Geldingadalur has experienced a significant uptick in seismic activity, intermittent eruptions follow for 100 years or so. This eruption could signal a re-awakening.

"It was a magical sight," says Mathews, "one I took especially to heart because it happened to be my birthday!" Talk about birthday candles...

    There's even a shooting star on the left!
