The 2014 Eruption in Holuhraun

As the eruption by Fagradalsfjall in the Reykjanes peninsula began, many feared that air traffic would halt as it did during the 2010 Eyjafjallajökull eruption. Lucky for us (and the rest of Europe) the Fagradalsfjall eruption is a fissure eruption that isn't coming up under the ocean, a lake, or a glacier. Instead, it produces slow-flowing lava that sputters up from a long fissure before lazily sliding down the valley until it cools from a bright red or yellow to a dull, craggy black. Only the steam rising from the fresh rock indicates the enormous heat that lies below. In fact, the eruption has a lot more in common with the 2014 eruption in Holuhraun, albeit on a much smaller scale.
