A second outburst of lava in under a year strongly suggests that the country’s Reykjanes Peninsula will become one of the most volcanically dynamic parts of the planet for several generations.
Less than a year has passed since lava stopped sputtering from Iceland’s Reykjanes Peninsula following the first major volcanic outburst from this region in almost 800 years. But now the island is once again bleeding molten rock. The start of a new eruption so soon after unrest in 2021 seems to underscore that this once quiescent peninsula has awoken from its long slumber.
