Iceland’s Reykjanes Volcanic Activity: Status Update for Travellers

REYKJAVÍK, 19 January 2026 – While Iceland’s famous Reykjanes Peninsula is not currently erupting, it remains in a state of significant geological unrest. The latest volcanic event, which began on 16 July 2025, concluded on 5 August, marking the twelfth eruption in the region since activity resumed in 2021. Authorities and scientists emphasise that Iceland is safe for visitors, with all international flights and the vast majority of tourist attractions operating as normal, but they continue to monitor the slow accumulation of magma that suggests further eruptions are likely in the coming months.
The Current Situation: A Pause, Not an End
As of mid-January 2026, there is no visible volcanic activity on the Reykjanes Peninsula. The Icelandic Meteorological Office (IMO) confirmed the end of the July-August 2025 eruption, which was a fissure eruption near the Sundhnúkur crater row, north of the town of Grindavík. This event was characteristic of the recent cycle: a localised lava flow with no production of the high-altitude ash clouds that disrupt aviation.
However, the IMO’s latest assessments indicate that magma continues to accumulate slowly beneath the Svartsengi area at a depth of approximately 4 kilometres. This ongoing uplift means the likelihood of a new magma intrusion and subsequent eruption remains elevated. The uncertainty regarding timing is high, with scientists stating the next event could occur within a timeframe spanning several months.
Key Facts for Travellers
| Aspect | Status as of January 2026 |
|---|---|
| Active Eruption | None. Last eruption ended 5 August 2025. |
| Flight Operations | Keflavík International Airport is open. All flights are operating on schedule. |
| General Travel Safety | Iceland is considered safe to visit. Tours across the country are running normally. |
| Blue Lagoon Access | Subject to short-notice closures if seismic activity increases. Visitors must check the official website for the latest status. |
| Grindavík Town | Largely evacuated and uninhabited due to volcanic risk. Access is restricted; guided tours may be available. |
| Scientific Outlook | Magma accumulation continues. A new eruption is possible within months, but the timing is unpredictable. |
Why This Cycle Differs from 2010
The recurrent eruptions on the Reykjanes Peninsula are fundamentally different from the highly disruptive 2010 eruption of Eyjafjallajökull, which paralysed European air travel. The current activity involves fissure eruptions, where lava flows from cracks in the ground. These events produce minimal explosive ash because there is no glacial ice interacting with the magma. Consequently, the ash plume is low and localised, posing no threat to aircraft engines at cruising altitude.
In contrast, the 2010 eruption was subglacial. The meeting of molten rock and ice caused a violent, explosive eruption that blasted fine glass-rich ash high into the jet stream, leading to widespread airspace closures.
Living with Fire: Iceland’s Preparedness
Volcanic activity is an integral part of Iceland’s geology, situated as it is on the Mid-Atlantic Ridge. The country has developed one of the world’s most sophisticated monitoring and response systems. The IMO, the Department of Civil Protection and Emergency Management, and university scientists maintain 24-hour surveillance using seismic networks, GPS stations, satellite data, and gas sensors.
This infrastructure allows for precautionary evacuations—like those of Grindavík and the Blue Lagoon—well in advance of any eruption, ensuring public safety. All critical infrastructure, including the main road to Keflavík Airport (Route 41), is built with these geological risks in mind and has remained unaffected.
Frequently Asked Questions
Should I cancel my upcoming trip to Iceland?
No. The Icelandic government and travel authorities consistently state that the country is open and safe for visitors. The volcanic activity is confined to a small, remote area of the Reykjanes Peninsula. Reykjavík, the Golden Circle, and all other regions are untouched and welcoming tourists.
Will my flight be cancelled?
Flights are operating normally. The nature of the recent eruptions does not produce the high-altitude ash clouds that necessitate flight cancellations. Passengers should always check with their airline for the most specific and up-to-date information.
Can I visit the eruption sites?
When an eruption is not ongoing, some areas may be accessible via designated hiking trails, such as those near Fagradalsfjall. However, the most recent Sundhnúkur crater area remains hazardous due to unstable ground, toxic gas pockets, and extreme heat, and is closed to the public. Access is strictly controlled by authorities, and visitors must heed all closures and advice from Safe Travel Iceland.
Where can I get reliable updates?
For official information, travellers should monitor:
- Icelandic Meteorological Office (IMO): For seismic and volcanic activity forecasts.
- Safe Travel Iceland: For safety advice and travel conditions.
- Icelandic Road Administration: For road closures and conditions.
- The Department of Civil Protection and Emergency Management: For official alerts.
