This event is a spectacular show of the earth's powers. Iceland, known as the land of fire and ice, sits on a volcanic hotspot in the North Atlantic, making it one of the world's best places to observe the phenomenon. Tourists, scientists, and volcano watchers will no doubt find it hard to stay away — especially as there are currently no threats to people or infrastructure.
While the volcano doesn't presently pose a risk to life — in part because of the government's pre-emptive and well-planned evacuation orders — there's no indication of how long the lava will flow. It's also unknown if this rapidly changing situation will deteriorate. This isn't a tourist attraction and emergency officials are absolutely correct to express caution about potential dangers in the future.
