On the Reykjanes Peninsula in the southwestern part of Iceland, a volcanic eruption could occur due to the likely accumulation of magma. The aviation color code has been upgraded to "yellow" for the region, including Keflavik International Airport, Iceland Review reported.
The Icelandic Meteorological Office said that while earthquakes are not uncommon in the area, "the fact that swelling occurs along with the swarm of earthquakes is cause for greater concern and closer monitoring."
Swelling by 3-4 mm occurs in the area of Torbjorn mountain, near the town of Grindavik. Most likely, it is a sign of magma accumulation at a depth of only a few kilometers. The Meteorological Service has strengthened round-the-clock monitoring of the area.
For nearly a week, a series of earthquakes shook the area around Grindavik, near the popular Blue Lagoon geothermal resort. The magnitude of the strongest earthquake was 3, 7.
In 2010, the eruption of the Eyjafjallajökull volcano in southern Iceland caused a huge cloud of smoke and ash, resulting in the cancellation of more than 100,000 flights.
