A geologically young land, Iceland is located on both the Iceland hotspot and the Mid-Atlantic Ridge, which runs right through it. This location means that the island is highly geologically active with earthquakes and volcanoes, notably Hekla, Eldgjá, Herðubreið and Eldfell. Eyjafjallajökull (1,666 m) erupted in 2010, disrupting European air traffic. To demonstrate the geothermal activity, the Icelandic Meteorological Office said that during a single week in February 2021, around 17,000 earthquakes have hit the southwestern region of Reykjanes.
