Iceland's Volcanic Activity Likely to Persist for Decades
An international team of geologists and volcanologists has found that Iceland's Reykjanes Peninsula has experienced eight volcanic eruptions over the past three years, with predictions of continued activity for decades. The researchers, from institutions including the Universities of Oregon and California at San Diego, have linked these eruptions to a shared magma reservoir located 5.5 to 7.4 miles beneath the Fagradalsfjall volcanic system. This magma reservoir is also identified as the main heat source for the Svartsengi-Fagradalsfjall-Krýsuvík area.
The study, published in the journal Terra Nova, highlights significant risks to local populations and critical infrastructure, such as Iceland's only international airport, geothermal power plants, and the Blue Lagoon geothermal spa. The town of Grindavík and surrounding areas have faced repeated evacuations due to the volcanic activity. Researchers emphasize the importance of preparedness, as the ongoing eruptions could have substantial impacts on Iceland's economy and infrastructure. The study also offers unique opportunities to understand how Icelandic lava fields develop and contribute to the formation of large flood basalt areas.
