Iceland, known for its stunning landscapes and geothermal wonders, is currently on high alert due to thousands of minor earthquakes that indicate a possible volcanic eruption. The Icelandic Met Office (IMO) has reported over 20,000 tremors since late October, with 1,400 occurring within a 24-hour period leading up to Thursday midday. The increased geological activity has prompted the closure of the famous Blue Lagoon, as a precautionary measure. The tremors are concentrated in the Reykjanes Peninsula, which was dormant for 800 years before an eruption in 2021.
According to the IMO, magma (molten rock) is accumulating at a depth of approximately 5km northwest of Thorbjorn mountain. The Blue Lagoon, a popular tourist attraction and therapeutic hot spring, is situated within close proximity to the mountain. To ensure the safety and well-being of their employees, the Blue Lagoon’s owners have decided to close the site until November 16th. This temporary closure reflects the concern surrounding the escalating geological activity.
The Met Office has reported the detection of a 5.0 magnitude earthquake, the most significant since the increased activity began, in the Fagradalsfjall volcanic area, approximately 30km from the capital city Reykjavik. In anticipation of a potential evacuation, Lilta Omarsdottir from the Icelandic Civil Protection Agency has been stationed in the nearby town of Grindavik. However, she emphasized that there is currently no immediate need for evacuation, but local authorities are prepared in case magma starts rising to the surface.
Volcanic eruptions occur when lighter magma rises to the earth’s surface from beneath the solid rock. However, Ms. Lilta assured the BBC that there is no risk of a massive explosion comparable to the 2010 Eyjafjallajokull eruption, which caused widespread air travel disruptions across northern Europe. The residents of Grindavik would receive approximately 36 hours’ notice before an imminent eruption occurs.
Iceland is renowned for its geological activity, being one of the most geographically active regions globally. The island nation boasts around 30 active volcanic sites. In July, the Fagradalsfjall area witnessed the eruption of the “world’s newest baby volcano” called Litli-Hrutur or Little Ram. Tourists flocked to witness this spectacle as it had been dormant for eight centuries until recent eruptions in 2021, 2022, and 2023.
While the current seismic events pose concerns for Iceland, it is crucial to understand that precautions and measures are in place to mitigate any potential risks. Authorities are closely monitoring the situation, and public safety remains a top priority. Visitors and locals should stay informed and follow instructions from local authorities to ensure their well-being in this dynamic natural environment.
