Litli-Hrútur's Volcanic Eruption: What You Need to Know

Heed this warning: the area around the ongoing eruption at Litli-Hrútur on the Reykjanes Peninsula is off-limits due to the high risk of exposure to poisonous volcanic gases leaking from fissures beneath the Earth's surface. That's the firm stand of geophysics professor and volcano expert Magnús Tumi Guðmundson, who's offering advice to the National Police.

The eruption, which started at 4.40pm GMT today, is far larger than any previous ones in the area, pumping out at least thrice as much lava as the 2021 eruption and an immense volume of gases.

Earlier, the Civil Protection and Emergency Management Department of the National Police had urged the general public to steer clear of the eruption site due to its unpredictability and ever-evolving nature.

Right now, the area is grappling with severe gas pollution. Experts say this eruption, which broke out this afternoon, dwarfs recent eruptions in scale.

Specialists from the Icelandic Meteorological Office are analyzing the concentration of gases released from the eruption. The findings will be available only tomorrow morning.

Unfortunate truth: the existing weather conditions intensify the risk of toxic gas accumulation. This odorless gas is highly hazardous when inhaled.

Behind the Scenes

  • The volcano has been associated with massive volumes of toxic gases, posing serious health risks to those in the vicinity of the eruption site[1][3][5].
  • Gases such as sulfur dioxide (SO₂)—typical in Icelandic volcanic eruptions and known to cause respiratory problems, acid rain, and adverse impacts on ecosystems[1][4]—are to blame.
  • Authorities have repeatedly warned that exposure to these gases can be fatal, particularly in areas close to or downwind of the eruption site[1][3][5].
  • Visual and monitoring reports indicate that the volcanic activity persists, with ongoing emissions of toxic gases and ash into the atmosphere[1][4].
  • Similar eruptions around the globe have shown that volcanic plumes can travel great distances, affecting air quality over extensive regions and endangering local communities and air traffic[2].
  • Local wildlife mortality events have been recorded in affected areas, linked to the toxic gas pollution from the eruption[3].
  • As long as the eruption continues, toxic gas emissions are expected to persist, with variations depending on eruption intensity and weather conditions[1][4].
  • Wind direction and speed will dictate the areas most vulnerable to gas dispersion. Swings in wind patterns could abruptly expose new regions to hazardous conditions.
  • Authorities and volcanologists forecast that the toxic gas threat will continue until the eruption subsides, underscoring the necessity of ongoing monitoring and safety alerts[1][5].
  • The eruption has led to evacuations, road closures, and warnings to the public to avoid the area due to the risk of toxic gas poisoning[1][4].
  • Agricultural lands, livestock, and natural habitats in the path of gas plumes are at risk, with potential long-term ecological repercussions[3].

  1. The ongoing volcanic eruption at Litli-Hrútur is associated with massive volumes of toxic gases, which pose serious health risks to those in the vicinity of the eruption site.
  2. An assessment of the health-and-wellness impacts of the eruption should include the potential risks posed by gases such as sulfur dioxide (SO₂), known to cause respiratory problems, acid rain, and adverse impacts on ecosystems.
  3. The Icelandic Meteorological Office's scientists are currently analyzing the concentration of gases released from the eruption, with findings expected tomorrow morning, which will be crucial in assessing the extent of the health risks.
  4. The environmental-science community should closely monitor the eruption's ongoing emissions of toxic gases and ash into the atmosphere, as changes in weather conditions can alter the areas most vulnerable to gas dispersion.
  5. In light of the ongoing eruption and associated toxic gas emissions, it's essential for authorities and volcanologists to continue issuing safety alerts and monitoring the eruption site to limit the potential harm to the local community and environment.
  6. This eruption's environmental impact extends beyond human health, as local wildlife mortality events have been recorded in affected areas, linked to the toxic gas pollution from the eruption.
