The Volcanic Eruption at Geldingadalir, Iceland
When one takes an international flight to Iceland, one usually lands at Keflavík Airport on the Reykjanes Peninsula. From there, it is a From there it is 30 miles (50 km) to Reykjavík. Those 30 miles contain some of the most desolate volcanic badlands that I have ever seen. It is south of that road, on the way to Grindavík that a fissure in the earth started belching out lava on March 19, 2021. It is still going strong, and it looks like it will destroy the road to Grindavík, forcing the locals to take a more roundabout route to the capital.
The area of the eruption is part of the Krýsuvík-Trölladyngja volcanic system on the Reykjanes Peninsula, a scene of active rifting between two major tectonic plates: the Eurasian and North American. The boundary between these two plates cuts north/south right through the west of Iceland. This is the first eruption on the Peninsula in over 800 years. You can read about the eruption at Hit Iceland and Wikipedia.
The Desolate Reykjanes Peninsula Terrain Seen from the Airport Bus to Reykjavík
I took the above picture from my bus to Reykjavík in June 2013. It amazed me on both my trips to Iceland that the road to the capital was so desolate, so uninhabited, for so many miles. At places, one could see geyser activity marked with little steam clouds. I can only speculate that the Icelanders knew this place was going to blow at some point, so they decided to stay away in droves.
Now, of course, tourists are flocking to the scene of the eruption, but they are warned that things can get ugly fast. In 1783, there was a major eruption along a 27 km fissure called Laki, killing some 9,000 Icelanders with the lava and poison gases associated with the event. You can read about it on the Scientific American website.
No one knows how long the eruption at Geldingadalir will continue, and how much the Peninsula will change as the result of the massive amounts of lava being pumped out.
