Context: Iceland is currently experiencing a significant increase in seismic activity, with around 1,400 earthquakes measured in the past 24 hours and over 24,000 recorded in the Reykjanes Peninsula since late October.
What are the reasons for the seismic activity in Iceland?
The seismic activity in Iceland is primarily due to its location on the Mid-Atlantic Ridge, where the Eurasian and North American tectonic plates meet. This geological setting makes Iceland prone to frequent earthquakes. The recent earthquake swarm is believed to be a result of movement and pressure changes associated with magma activity beneath the Earth’s surface, indicating a potential precursor to a volcanic eruption.
- Fagradalsfjall lies about 40 km to the southwest of Reykjavík and is the “world’s newest baby volcano.” It had been dormant for eight centuries before erupting in 2021, 2022 and 2023.
What is the Mid-Atlantic Ridge?
The Mid-Atlantic Ridge is a mid-ocean ridge (a divergent or constructive plate boundary) located along the floor of the Atlantic Ocean and part of the longest mountain range in the world. In the North Atlantic, the ridge separates the North American from the Eurasian Plate and the African Plate, north and south of the Azores Triple Junction.
