Current Volcanic Situation in Reykjanes

Currently, no eruption is ongoing in the Reykjanes Peninsula. However, Icelandic authorities report an increased possibility of volcanic activity in the coming weeks. This region, known for its exceptional geothermal activity that you can admire at the Blue Lagoon, is currently experiencing land uplift and magma accumulation beneath Svartsengi.

Seismic activity in the Sundhnúksgígaröðin region remains relatively stable, with approximately five earthquakes per day in February. These tremors are generally of low intensity and are part of everyday life in Iceland. If you visit the Katla Geopark, you can learn more about this incredible, constantly evolving geology.

Areas to Watch Particularly

According to experts, the areas most likely to experience an eruption are located between Sundhnúkur and Stóra-Skógfell, as was the case for six of the last seven eruptions since late 2023. The eruptive fissure could then propagate towards the northeast and/or southwest over several kilometers.

There is also a possibility of an eruption near or south of Hagafell, as was the case in January 2024. This scenario would offer a longer warning time of about 1 to 5 hours, unlike eruptions between Sundhnúkur and Stóra-Skögfell which could occur with very little or no warning.

Evacuation Routes in Iceland: Main Hazards in Case of Eruption 🚨

If you’re visiting the Reykjanes Peninsula, it’s essential to know the main volcanic risks and corresponding evacuation routes. This information is not meant to frighten you but to allow you to travel with confidence and responsibility.

Potential Risks

In case of an eruption, several phenomena could occur:

• Opening of eruptive fissures: This process can be very rapid, reaching several kilometers in less than an hour. During previous events, eruptive fissures continued to propagate between 40 minutes and 7 hours and reached lengths between 1.7 and 6 km.
• Lava flows: Lava could reach Grindavíkurvegur or Svartsengi in less than 1.5 hours. If you’ve planned to observe whales in Iceland in winter, make sure to regularly check updates regarding road accessibility.
• Gas pollution: A strong initial phase in an unfavorable wind direction could pose a danger due to gas pollution within a radius of up to 1 km.
• Explosive activity: This could occur if lava flows over ponds or comes into contact with groundwater.

In case of an eruption near or south of Hagafell, additional hazards should be considered:

• Lava flows toward roads: Lava could reach Nesvegur and Suðurstrandavegur within 1.5 hours and potentially block all evacuation routes from Grindavík in about 6 hours.
• Lava reaching the sea: Lava could reach the sea east of Grindavík in 1.5 to 3 hours, creating extremely dangerous conditions within a 200-meter radius of the point where lava enters the sea.

Reykjanes Evacuation Routes Map: Volcanic Risk Zones

The current hazard map, valid until March 18, 2025 (unless there are new developments), divides the region into several zones with different danger levels. Each zone has clearly marked evacuation routes that you should identify as soon as you arrive.

The colors on the map represent the overall hazard level in each zone:

• 🔴 Red zone: Extreme danger, access forbidden
• 🟠 Orange zone: High danger, immediate evacuation in case of alert
• 🟡 Yellow zone: Moderate danger, stay vigilant and ready to evacuate
• 🟢 Green zone: Relative safety zone

Evacuation Routes in Reykjanes, Iceland: Detailed Guide by Zone

Zone 4: The Town of Grindavík

The town of Grindavík is currently open to visitors, but authorities advise against going there due to its proximity to potential eruption sites. The town has been heavily affected by earthquakes and recent volcanic activity.

Grindavík evacuation routes:

• North route: Follow the main road (Grindavíkurvegur/Route 43) towards Reykjavík
• East route: Use Suðurstrandavegur (Route 427) towards Þorlákshöfn
• Assembly points: Gathering areas are clearly identified in the town by green signs

⚠️ In case of an eruption, an alarm will sound in the town to signal evacuation. Note upon your arrival the closest and quickest way out of town. Evacuation routes are clearly marked.

If you want to discover the Solheimasandur plane wreck, know that this attraction is located east of the peninsula and is generally less affected by current volcanic activity.

Zone 3: Sundhnúkagígar Eruption Site

This area has an increased possibility of volcanic eruption. Scientists state that an eruption could occur without any prior warning. Therefore, hiking to the eruption site is strongly discouraged.

Sundhnúkagígar evacuation routes:

• Evacuation to the west: Follow the marked trails towards Route 43
• Evacuation to the north: Use the marked paths towards Route 41
• Exit points: Clearly visible evacuation signs indicate the fastest exits

⚠️ In this area, the ground is unstable with cracks and holes that may not be visible. Never venture off the marked trails.

If you’re interested in volcanic phenomena while staying safe, I instead recommend visiting Geysir, which offers an impressive geothermal spectacle without the immediate dangers of an active eruption zone.

Mt. Fagradalsfjall (2021-2023 Eruption Site)

Mount Fagradalsfjall, site of the 2021-2023 eruptions, remains accessible but could be temporarily closed in case of an eruption at Sundhnúkagígar. If you visit this area, stay alert for any signs of eruption and be ready to evacuate the area immediately if necessary.

Recommended routes and evacuation points:

• P1: Recommended parking point, with a well-marked hiking trail to the viewpoint of the eruption site (red trail on the map)
• P2: Another parking option for a shorter hike to one of the lava flows at Nátthagi
• Evacuation routes: Yellow signs indicate the fastest evacuation paths

⚠️ Disable airplane mode on your phones during your visit, as information regarding an eruption may be transmitted via SMS. This area features mountainous terrain, dress according to the weather.
