The risk of a volcanic eruption on Iceland's Reykjanes Peninsula is still very high, with ground deformation and earthquakes continuing along the magma dike — a near-vertical underground tunnel running from a magma chamber towards Earth's surface.
The 9.3-mile (15 kilometers) magma dike is located between Sundhnúk in the northeast to the town of Grindavík and into the sea. It formed after thousands of earthquakes hit the region in October and November. On Nov. 10, residents of Grindavík were evacuated, and authorities warned of an imminent eruption — potentially within just days.
