Iceland’s Reykjanes Peninsula Erupts Again: Seventh Volcano Event Since December
A volcano near Reykjavik, Iceland erupted on Wednesday night. This event marks the seventh eruption in the area since December. The fissure length is about 3 kilometers (1.9 miles), according to the Icelandic Met Office.
The eruption began shortly after 11 p.m. local time. A Met Office update about three hours later indicated that the fissure had stopped expanding. Air traffic to and from Iceland continued normally on Thursday. The eruption was smaller than the previous one on August 22, which opened a 4-kilometer (2.5-mile) fissure.
Nearby, a geothermal power plant and hotels at the Blue Lagoon were evacuated. The Blue Lagoon has faced multiple closures due to volcanic activity over the last year.
What are the main geological factors contributing to the frequent volcanic eruptions on the Reykjanes Peninsula?
Interview with Dr. Sigurdur Bjornsson, Geologist at the Icelandic Meteorological Office
NewsDirectory3: Thank you, Dr. Bjornsson, for taking the time to speak with us today. Can you provide an overview of the recent eruption near Reykjavik?
Dr. Bjornsson: Certainly. The eruption on Wednesday night marked the seventh event in the Reykjanes Peninsula since our monitoring began last December. The fissure measures approximately 3 kilometers in length. It began just after 11 p.m. local time and has been characterized as relatively small compared to earlier eruptions, such as the one on August 22, which had a 4-kilometer fissure.
NewsDirectory3: What can you tell us about the impact of this eruption?
Dr. Bjornsson: The impact has been significant in terms of local evacuations. Authorities evacuated around 60 people from the nearby town, including staff and guests from the Blue Lagoon Hotel and personnel at the Svartsengi Power Plant. Thankfully, the Blue Lagoon was empty at the time of the eruption as it occurred after hours. Fortunately, air traffic remained unaffected, allowing flights to and from Iceland to continue normally.
NewsDirectory3: Why have the residents of this region experienced multiple eruptions since January 2020?
Dr. Bjornsson: The Reykjanes Peninsula sits on the boundary between the North American and Eurasian tectonic plates, making it one of the most volcanically active regions in Iceland. Since January 2020, we have documented a total of 10 eruptions. The activity is generally driven by the movements of magma and the underlying tectonic processes, which create the conditions for such eruptions. Last year alone, we recorded over 1,000 earthquakes in a single day, a clear indication of the underlying geological activity.
NewsDirectory3: What precautions are being taken to manage the situation and protect residents?
Dr. Bjornsson: The authorities have been proactive in their response to the volcanic activity. Real-time monitoring of seismic activity and gas emissions is underway, and we provide regular updates to local communities. Evacuations are performed as necessary, especially in areas deemed at risk. Safety and preparedness training for residents is also critical, given the frequency of eruptions in this region.
NewsDirectory3: Given the patterns we’ve seen, what can we expect moving forward?
Dr. Bjornsson: While we cannot predict the exact timing or nature of future eruptions, we expect that activity will likely continue in the region. Our focus will remain on closely monitoring geological developments and ensuring the safety and well-being of local residents.
NewsDirectory3: Thank you for your insights, Dr. Bjornsson. It’s crucial for the public to stay informed during these times.
Dr. Bjornsson: Thank you for having me. It’s essential to spread awareness and ensure we remain vigilant of our natural surroundings.
Authorities evacuated approximately 60 people from the nearby town. The evacuation included the Svartsengi Power Plant and the Blue Lagoon Hotel. The hotel was empty since the eruption started after hours.
Since January 2020, Iceland’s Reykjanes Peninsula has seen 10 eruptions. Iceland, with nearly 400,000 residents, is in a volcanic region. It lies on the active boundary between North America and Europe, experiencing over 1,000 earthquakes in a single day last year.
