How to Help People During a Volcanic Eruption in Iceland

Quick answer: To help people during a volcanic eruption in Iceland, keep them out of closed eruption areas, check the Icelandic Meteorological Office and Civil Protection instructions, and call 112 for immediate danger. Help people leave an affected area early when authorities direct them, verify that roads remain open, and take harmful volcanic gases seriously. Do not enter new lava fields, drive through barriers or send volunteers into an eruption area to retrieve luggage, vehicles or photographs. The safest help is often accurate information, early accessible transport and a verified report to emergency services.

Iceland’s volcanic hazards are highly local. An eruption on the Reykjanes Peninsula near Grindavík and Svartsengi is not automatically a danger to every district or traveller on the island. Equally, an eruption may create dangerous gases and fissures outside the most dramatic visible lava front. Use the Icelandic Meteorological Office (IMO), the official SafeTravel Iceland service and 112 Iceland to find authoritative information. These are the sources to consult for current conditions; this guide does not claim that a particular site, road or town is currently safe.

The practical sequence is simple: identify the location and official instruction; remove people from danger without entering it yourself; communicate precise needs; and coordinate any later assistance through recognised responders. A person with asthma may need to avoid sulfur dioxide exposure, a visiting driver may need a verified detour, and a resident told to evacuate may need essential medication or disability-access arrangements. Each problem calls for a different action.

First 10 things to do to help another person

Make yourself safe. Do not approach fresh lava, an active fissure, a gas plume, unstable ground or a police roadblock.
Verify the correct area. Check IMO warnings, SafeTravel alerts and Civil Protection or police instructions for the exact location.
Call 112 for immediate danger. Give the place, GPS coordinates if reliably known, injury or breathing symptoms, number of people and the nature of the hazard.
Follow any evacuation order. Help people leave by the permitted route before conditions deteriorate; never advise them to stay for photographs or belongings.
Check road status. Use Iceland’s official road and traffic information, and respect every closure.
Help people avoid gas exposure. Follow official air-quality guidance; stay away from low-lying areas when volcanic gas is a concern.
Ask about access needs. A person may require mobility assistance, medication, transport or an interpreter.
Keep families informed privately. Provide a confirmed safe destination and the time last verified; protect children’s names and precise accommodation details.
Do not self-deploy. Leave searches in closed areas, hazardous gas zones and lava-field access to trained teams.
After the immediate incident, confirm needs. Offer help with safe accommodation, transport, prescriptions, essential documents and official recovery information.

Who to call and which Icelandic authorities to check

112 — emergency: Iceland’s national emergency number for police, fire, ambulance and search-and-rescue coordination; available around the clock. Use it for serious injury, entrapment, severe breathing difficulty or immediate danger.
112 Iceland app: official emergency communication and location-support options; see 112 Iceland and follow the app’s current instructions.
Icelandic Meteorological Office: scientific monitoring and hazard updates and volcanic-gas information.
SafeTravel: travel alerts, route information and emergency preparedness operated by the Icelandic Association for Search and Rescue (ICE-SAR).
Official road authority: live road notifications and restrictions; posted closures and police instructions override a navigation app.
Civil Protection, police and municipal authorities: official area restrictions, evacuation destinations, re-entry permissions and local support; obtain the active message through official channels.

The official 112 Iceland service explains that emergency coordinators receive calls continuously and dispatch the appropriate responders. If a person has a serious problem, call 112 first rather than asking a volunteer group to find the correct specialist. If the mobile network is unreliable, keep messages short, conserve power, and use alternate official communication arrangements when available.

What makes volcanic eruptions in Iceland dangerous?

1. Lava flows and newly formed ground

Fresh lava may appear spectacular and later develop a dark surface crust, but the crust does not prove that the ground beneath has cooled or can support a person’s weight. Lava fields can include hot openings, unstable edges, hidden fissures and gas release. Do not step onto lava to rescue a pet, drone or bag. An open viewpoint is safe only while the responsible authority allows access; a social-media video or commercial tour advertisement does not confer permission.

2. Sulfur dioxide and other volcanic gases

The IMO’s volcanic-gas reference identifies sulfur dioxide (SO₂), carbon dioxide (CO₂) and hydrogen sulfide (H₂S) among important gases. Sulfur dioxide can irritate eyes and airways, particularly for people with asthma. Carbon dioxide can accumulate in low ground and displace breathable air. Some gases can be dangerous even where there is little visible smoke. A common particulate face mask does not make a toxic gas plume safe.

3. Fissures, earthquakes and moving ground

In some eruptions, magma intrusion and ground movement can damage roads, pipes and buildings before lava appears. A familiar parking area, pedestrian path or road shoulder may have acquired fissures that are difficult to see. Avoid barriers and affected ground. Do not tell another person to approach a crack to measure it or film it; report the suspected hazard to the appropriate authority from a safe position.

4. Wild weather and isolated roads

An Icelandic volcanic event may coincide with wind, cold, snow or limited daylight. A detour can take far longer than a traveller expects, and fuel or communications may be limited. Check weather and road conditions before arranging transport, rather than promising a quick pickup by a route that is actually closed.

The difference between an eruption alert and an evacuation order

Scientific monitoring assesses whether volcanic unrest, magma movement or eruption activity is possible. Police and Civil Protection authorities decide which areas are closed, who must leave and when re-entry may be allowed. These two kinds of information are connected, but they are not interchangeable. A scientific alert cannot be interpreted as permission to cross a cordon. Equally, a traveller might encounter a road closure or evacuation order even when there is no lava visible at that location.

For the Reykjanes–Svartsengi system, the IMO publishes detailed hazard assessments. Its monitoring updates explain that magma can accumulate between eruptions and that the timing of a new intrusion can remain uncertain. Don’t publish an exact predicted eruption hour, claim an eruption is over because several quiet days passed, or promise that a closed site will reopen by a fixed date.

How to assist someone when evacuation is announced

Ask whether the person has received the official order and understands which streets or districts it covers.
Confirm the permitted route and destination through Civil Protection, local police or authorised reception staff.
Offer a specific task such as making a family call, checking a medical appointment, finding accessible transport or carrying an essential item if safe.
Help gather critical medication, glasses, mobility equipment, a phone, charger, documents and necessary infant supplies only if this does not delay departure.
Keep families together where feasible and decide who will receive a private check-in message.
Do not obstruct a road closure or evacuation convoy with private vehicles.
Never go back into a restricted zone for property or to find a pet without an authorised response plan.
After arrival, confirm whether the destination actually provides accommodation, medical care or another service; an assembly point is not automatically an overnight shelter.

What if someone says, ‘I only need five minutes to get my things’?

In a rapidly changing volcanic emergency, five minutes is not guaranteed to remain available. Explain that the direction to evacuate is about avoiding hazards such as fissure opening, gas accumulation and road loss. Help identify a safe method to obtain essential care later, using authorised municipal or emergency services. Do not make yourself responsible for a dangerous return journey.

What if the person has reduced mobility?

Ask how the person ordinarily transfers and travels, which devices and medical support are essential, and what the destination must provide. Request authorised accessible transport early. Do not carry a person or wheelchair across damaged pavement, hot ground or an unstable roadside without proper assistance. If a person cannot evacuate safely under their own power, tell 112 or the coordinating authority their exact location and the support required.

If the person may be exposed to volcanic gas

From a safe location, ask about symptoms such as serious breathlessness, wheezing, chest pain, dizziness, confusion or collapse. For severe symptoms or immediate danger, call 112 and follow the emergency operator. Move away from a suspected gas area when that can be done safely and in accordance with official directions. Do not send an untrained neighbour into a low-lying area to check on an unresponsive person.

Official guidance may direct residents away from an area or recommend temporary indoor exposure reduction depending on the hazard. If indoor shelter is advised, close windows and adjust ventilation as directed by public-health authorities. But closing windows is not a substitute for evacuation where an order applies. A cloth, surgical mask or N95 respirator filters particles to varying degrees; none is suitable protection against all hazardous volcanic gases.

Why low-lying places deserve special attention

The IMO explains that carbon dioxide is denser than air and may collect in depressions. This means a ditch, valley floor or sheltered low spot may be dangerous even when a nearby hill seems clearer. Never direct a person to hide in a low ditch from a volcanic gas cloud. If gas is suspected, move along the official safe route and let trained teams assess conditions.

People with asthma or other respiratory illness

Ask whether they have their prescribed medication and a clinician’s action plan. If symptoms worsen, seek medical advice early. If a person struggles to speak or breathe, collapses, or shows serious distress, call 112. Do not prescribe somebody else’s inhaler or recommend an improvised dosage.

Visitors, tourists and people unfamiliar with Iceland

A traveller may see an eruption image online and think that an official closure is only a suggestion. It is not. SafeTravel Iceland provides visitor-focused warnings and planning advice, while the road service shows closures and traffic notices. Hotels, guides and tour operators can help interpret local instructions but cannot overrule police restrictions.

A visitor has no rented car or local friends

Help them identify a lawful transport option and safe accommodation outside the restricted zone. Ask whether they require medical assistance, travel-document support or accessible transport. Avoid promising a route without checking road closures. Emergency evacuation arrangements must be confirmed with official coordinators.

A friend wants to walk across a closed trail to see the lava

Explain that a closed eruption area may contain hot fissures, gas and ground collapse risk unrelated to how dramatic the surface looks. Share the official closure and offer a permitted viewpoint or activity only if authorities have designated one. Do not post directions for bypassing gates, ropes, police vehicles or warning signs.

Should travellers leave Iceland entirely?

Do not infer a nationwide travel emergency from one local volcanic event. The relevant decision depends on official travel advisories, road and airport conditions, the visitor’s specific destination and health needs. Contact the carrier and accommodation provider for verified changes; help the person follow local restrictions without unnecessarily alarming people elsewhere on the island.

How to communicate clearly when the situation changes

A useful message has four parts: place, authority, time and action. For example: “According to the police update issued at [time], access to [named road] is closed. Do not drive there. Check the official road page before travelling.” If you cannot verify the update, mark it unconfirmed and do not circulate a route as safe.

Give exact Icelandic place names when possible; Reykjanes is a peninsula, Grindavík a town, Svartsengi an area, and Reykjanes–Svartsengi refers to volcanic-system activity. They are not all interchangeable locations. An alert about a fissure row is not automatically an instruction that every business in a region has closed.

What to do if someone is injured or missing

Call 112 for immediate danger or serious injury; give the last confirmed location and nature of the hazard.
Provide GPS coordinates if you have them from a reliable device, along with an understandable road or landmark.
Say what is known and what is uncertain: ‘last seen at 13:20 near the gate’ is different from ‘confirmed trapped in lava’.
Identify mobility, medication or communication needs only as relevant to responders.
Do not enter a closed site, active lava field or gas area to search.
Keep access routes clear and avoid publishing sensitive information about the missing person or children.
Follow the emergency service’s instructions on how to contact the family and when to provide updates.

After evacuation: how to help families recover

Once immediate danger has passed, affected households may still need accommodation, employment information, school continuity, transport, insurance documents and healthcare. A family forced out of its home needs a different form of assistance from a tourist whose booked road is closed for a day. Ask what the person wants, then help with one manageable task.

Safe accommodation: check authorised temporary housing or a verified hotel; confirm that it is reachable and appropriate for mobility and medical needs.
Health and prescriptions: help arrange contact with a pharmacy, clinic or ongoing care provider, especially if medication or medical equipment is missing.
Family contact: facilitate private messages and avoid publishing someone’s medical condition or temporary address.
Work, school and travel: help obtain official closure notices or documentation without guessing reopening dates.
Property and insurance: refer to authorities, insurers and recognised support centres for records and next steps; do not encourage unauthorised entry.
Long-term contact: call again after a few days. Recovery and displacement may last much longer than public attention.

How to volunteer or donate responsibly

Iceland’s search-and-rescue association, ICE-SAR, operates SafeTravel and coordinates trained rescue work. Interested supporters can use verified official channels and ask about structured volunteer opportunities. Do not interpret willingness to help as authorisation to conduct technical rescue, enter a gas-affected site or drive past police. Recognised responders may need safe communications and logistics support more than extra vehicles near a closure.

If an appeal seeks funds or supplies, check the organisation, destination and what the donation supports. Displaced people may be better served by accommodation, transport or administrative help than by piles of unrequested clothes. A short, concrete offer—“I can help call the insurer or pick up essential medicine from an open pharmacy”—is often more useful than a general promise.

Four real situations and the safer response

A relative is inside a town receiving an evacuation order

Check the authority’s instructions, assist with safe transport and essential medication, and confirm the permitted destination. Do not advise the relative to wait because there is no visible lava yet. If access is lost or medical help is required, tell 112 precisely where they are.

A visitor is standing near a recently cooled lava field

Ask them to return to the legal marked area and avoid stepping onto the lava. Share the official closure notice. Do not approach the field yourself to bring them a camera or help take photographs.

A driver says their navigation app shows a shortcut past a barrier

Tell the driver to respect the closure and check official road notifications. Apps may retain stale route geometry and cannot verify gas exposure or ground safety. Provide the road name and location to authorities if someone is stuck.

An older person has breathing difficulty while volcanic gas is reported

Seek urgent medical assistance if breathing is severe or worsening. From safety, help reduce exposure as directed and ensure they have their prescribed medication. Do not send a family member into low ground or suggest that a dust mask makes the area safe.

Frequently asked questions

What emergency number should I use in Iceland?

112 is Iceland’s national emergency number, available day and night. It coordinates police, ambulance, fire and rescue responses.

Is a road safe if the lava has stopped moving?

Not necessarily. Heat, gas, fissures, damaged roadbeds and police restrictions can remain. A road is usable only when authorities reopen it.

Can an N95 mask protect me from volcanic gas?

No. A particulate respirator is not a reliable protection against dangerous concentrations of sulfur dioxide, carbon dioxide or other volcanic gases. Leave the affected area or follow the official shelter/evacuation instruction.

Do all eruptions mean Iceland’s airport is closed?

No. Travel disruptions depend on the location, type of eruption and official aviation decisions. Check the current airport and carrier notices, not a general headline.

How can I help if I am far from the eruption area?

Contact loved ones privately, help verify official instructions and travel alternatives, support recognised relief or rescue organisations, and avoid driving into restricted areas.

What if the science page says activity has decreased?

That does not itself reopen a closed road or prove an eruption period has ended. Use the official Civil Protection or police decision for restrictions and the IMO for scientific updates.
