Massive Gas Cloud from Iceland’s Volcanic Eruption
A massive cloud of toxic gas, containing sulfur dioxide, has been released from Iceland’s ongoing volcanic eruption and is now moving across northern Europe. Scientists tracking the cloud have raised concerns about its potential impact on the ozone layer above the Arctic.
Volcanic Eruption in Iceland
An underground volcano erupted for the fourth time in Iceland’s Reykjanes Peninsula on March 16, opening up the largest fissure of the current eruption cycle. The eruption resulted in a massive lava flow that narrowly avoided reaching the evacuated town of Grindavík.
Release of Sulfur Dioxide
Despite the lava not reaching the sea, the eruption released significant amounts of sulfur dioxide, a toxic and colorless gas that can be hazardous in high concentrations. On March 17, the volcano emitted 110 pounds of sulfur dioxide per second, leading to evacuations at the Svartsengi power plant and advisories for locals to stay indoors.
Movement of the Gas Cloud
While sulfur dioxide emissions have since decreased, data from the Copernicus Atmosphere Monitoring Service (CAMS) revealed a concentrated column of gas reaching 3 miles in height and drifting towards other nations in northern Europe. The cloud has already passed the United Kingdom and is heading towards Scandinavia.
Monitoring and Impact Assessment
CAMS, part of the European Union’s Copernicus programme, continues to track the gas plume. Senior CAMS scientist Mark Parrington stated that they do not anticipate any significant impact on surface air quality or climate. However, monitoring the situation remains crucial to assess any potential developments.
