After weeks of anticipation, a volcanic eruption in Iceland’s most populated area sent lava spewing into the night sky late Monday and pushed the authorities into action mode Tuesday. The eruption, which was larger than volcanologists had predicted, happened not far from an evacuated town and a power plant.
Iceland is no stranger to volcanic eruptions, and the authorities quickly moved to reassure the public that there was no immediate threat to life. “We are prepared and remain vigilant,” President Gudni Johannesson, wrote on the social platform X.
They also stressed that travel was not affected — a clear attempt to fend off concerns of a repeat of 2010, when an ash cloud from another eruption in Iceland snarled flights across Europe.
Here’s what to know about the eruption.
What happened?
The eruption began late Monday, with fountains of lava pouring from a fissure on the Reykjanes Peninsula, the most populated region in Iceland and home to its capital, Reykjavik. Helicopter video shared by Iceland’s Civil Defense showed steam rising from a glowing, snaking river of lava.
Volcanologists initially said that the eruption had occurred in one of the worst possible locations. The fissure, which is about 2.5 miles long, is not far from the Svartsengi power plant, a geothermal facility. And it is just under two miles from Grindavik, a town of more than 3,500 that was evacuated last month after heightened seismic activity prompted concerns that an eruption was likely.
But after flying over the eruption site, volcanologists said that the immediate situation appeared less dire than initially feared.
Are people at risk?
Volcanologists noted that the direction of the lava’s flow was unpredictable. And although the Icelandic Meteorological Office said on Tuesday morning that the eruption’s “intensity” was decreasing, it was not immediately clear how long it would go on.
“The fact that the activity is decreasing already is not an indication of how long the eruption will last, but rather that the eruption is reaching a state of equilibrium,” the Meteorological Office said in a statement.
Yet because the affected area had previously been evacuated, the eruption “does not pose immediate threat to people,” Iceland’s tourist board said in a statement on Tuesday morning.
The area was closed to traffic, and the risk to nearby energy infrastructure was being assessed, Iceland’s government added in a statement.
The authorities nevertheless warned against getting too close, with Hjordis Gudmundsdottir, a spokeswoman for the Department of Civil Protection, emphasizing that this was “no tourist volcano.”
Is it affecting travel and tourism?
Iceland’s authorities had raised the aviation alert to orange, because ash from a volcanic eruption could pose a risk to aircraft flying in the North Atlantic.
But as of Tuesday morning, all flights to and from the country were operating on schedule, according to a statement from Iceland’s tourist board. It also noted that previous eruptions in the area had not affected air travel.
The eruption did catch some in Iceland by surprise, given that concerns of an imminent eruption had diminished in recent days. The nearby tourist meeca, the Blue Lagoon, which had closed in November because of earthquake activity associated with potential volcanic eruptions, had just reopened for guests on Sunday.
On Tuesday morning, the site issued a statement saying that it would again temporarily shut down.
Overall, Sigurdur Ingi Johannsson, the country’s infrastructure minister, told RUV, the national broadcaster, “We seem to have been quite lucky,” adding, “We hope that will continue.”
How often do volcanic eruptions occur in Iceland?
Volcanic eruptions are not uncommon in Iceland, which has fewer than 400,000 residents and about 130 volcanoes. In just the past two years, there have been four eruptions on the Reykjanes Peninsula, the scene of the latest lava flow.
One of Iceland’s most memorable eruptions involved the Eyjafjallajokull volcano in 2010. Although it was relatively small and caused no fatalities, the impact was widespread because a resulting ash cloud grounded much of Europe’s air travel for more than a week.
Iceland straddles two tectonic plates, which are themselves divided by an undersea mountain chain that oozes molten hot rock.
Earthquakes occur when the magma pushes through the plates, and starting in late October, a rise in seismic activity was detected, with tens of thousands of earthquakes reported in the Reykjanes Peninsula. At one point there were as many as 1,400 in a single 24-hour period.
That raised concerns that a significant eruption would soon occur. But when Grindavik was ordered evacuated on Nov. 11, the authorities said in a statement that the country was “highly prepared for such events.”
“Iceland has one of the world’s most effective volcanic preparedness measures,” Iceland’s Department of Civil Protection and Emergency Management said on its website.
