Lava flows from long cracks

The outbreaks, known as fissure eruptions, are characterised by lava flows emerging from long cracks in the Earth's crust, rather than from a central crater.

The Reykjanes volcanic eruptions have, so far, not threatened Iceland's capital, Reykjavik, or released substantial ash into the stratosphere, thereby preventing disruptions to air travel.

The nearby fishing town of Grindavik, which had around 4,000 residents before a 2023 evacuation, remains largely abandoned due to ongoing risks from lava flows and frequent earthquakes.
