Is Iceland’s Katla Volcano Really About To Erupt?

You may have heard that Katla, an Icelandic volcano, will shut and emerge down European airspace in such a way that would make the Eyjafjallajkull occasion in 2010 appear like absolutely nothing more than a bonfire. The amusing thing is that none of this holds true.

These claims are based upon a remarkable brand-new research study that specifically does not make any predictive claims about the volcano. The paper’s lead author, Dr Evgenia Ilyinskaya of the University of Leeds, required to Twitter to lament how the research study has actually been depicted by the press as something it’ s not.


Katla is definitely something volcanologists are keeping their eyes on. Consisted of a system of cracks not unlike those seen on Kilauea just recently, it includes a main volcano. A big ice cap, M ý rdalsjkull, fills the crater.

In the last 1,100 years, Katla has actually emerged 20 times , frequently accompanied by flash floods as the ice cap quickly melts. These occasions, called jkulhlaups , are cause for issue since they can take place extremely rapidly and clean into valleys that might have lots of individuals.

Jkulhlaups, which aren’ t special to Katla, happen from time to time . A significant eruption at Katla in the mid-18th century , nevertheless, stands apart: it caused a jkulhlaup with a circulation that, per Wired , surpassed that of the Nile, Mississippi, Amazon, and Yangtze integrated.

Katla’ s eruptions can likewise create imposing ash columns, which can impact flight. The last time this took place remained in 1918, when an eruption was effective sufficient to break through M ý rdalsjkull and produce an ash column 14 kilometers (8.7 miles) high.

Unsurprisingly, it’ s a greatly monitored volcano. Forecasting when it may emerge isn’ t yet possible, and any claims otherwise are incorrect.

Katla’ s eruptions wear ’ t follow any clear pattern, and like all volcanoes, it’s geologically distinct, so generalizations can’ t be made. All anybody can do is go over the risks, and keep an eye out for indications of lava increasing to the surface area.

The brand-new paper, released in Geophysical Research Letters , doesn’ t discuss forecast. The media typically wishes to turn significant volcano discoveries into stories of impending eruption, however typically , that’ s not the case.


This research study– which even has a plain language summary to guarantee individuals wear’ t get the incorrect concept– discovered that Katla produces plenty more CO2 into the environment than formerly believed. The group discovered that Katla alone is accountable for 5 percent of the world’ s volcanic CO 2 emissions.

That’ s extraordinary in itself, and recommends there are procedures going on underneath the surface area that we’ ve yet to completely understand. Which magmatic source, exactly, is launching this gas?

This work likewise highlights that natural sources of CO2, especially subglacial volcanoes, require more accurate measurements to enhance the precision of environment designs. Is Katla an exception to the guideline of subglacial volcanoes, or do they all drain way more CO2 than anticipated?

In case you were questioning: no, this doesn’ t mean environment designs are incorrect, and yes , volcanic CO2 emissions still fade into insignificance compared to the quantity and rate of CO2 humankind is producing.

This is a great paper, however one that has actually been misrepresented in journalism. Together with Ilyinskaya, the Icelandic Institute of Earth Sciences — not included with the research study — highlights that the paper’ s measurements “ do not forecast the size and magnitude of the next eruption, ” nor when it’ll take place. They might assist enhance eruption projections, however forecasts are not made.

There are no indications that Katla will emerge. Keep in mind the principle : if it’ s being reported that an eruption impends, or a significant quake will take place, it probably isn’ t real . Rely on researchers, not sensationalism.
