Steps to Take if a Natural Disaster Warning Is Issued While Abroad

A natural disaster warning issued while you are overseas confronts you with a compressed timeline, incomplete information, and decisions that have direct consequences for your survival and that of anyone travelling with you. The fundamental error most travellers make is treating a warning as an invitation to gather more information before acting. Every government emergency guidance framework reviewed for this article — from the FCDO’s own overseas crisis guidance to the detailed disaster response protocols published by the UK’s Prepare Campaign and Australia’s Smartraveller — is built on a single shared principle: time is the resource you cannot recover. Act while you have it.

What follows is a reported breakdown of the specific steps governments advise, in the sequence they advise them, covering the full arc from the moment a warning is received through the period of immediate danger and into the critical hours and days that follow.

Before the Warning: The Preparation That Makes the Difference

It is impossible to cover natural disaster response without acknowledging that the travellers who fare best in these situations are those who did their preparation before the crisis materialised. The FCDO’s guidance at gov.uk/guidance/extreme-weather-and-natural-hazards makes the case for pre-departure research plainly: extreme weather occurs and natural hazards exist across the world and may affect travellers or those living overseas, including events that could trigger other risks such as landslides after heavy rains or earthquakes, and aftershocks or outbreaks of diseases. GOV.UK

Before travelling to any destination where natural hazard risk is elevated — and destinations such as Japan, Indonesia, the Philippines, the Caribbean, Central America, and large parts of South and Southeast Asia carry significant year-round risk — the FCDO recommends that travellers sign up to receive email alerts when FCDO travel advice is updated, keep in touch with their travel or tour operator and hotel, be familiar with advice that is specific for hazards such as “drop, cover, hold” in an earthquake, and be prepared in case they need to move to a safe place at short notice — keeping essential items and supplies such as travel documents and essential medication together. GOV.UK

Travel Warning Check includes natural hazard risk as one of its assessed categories in the full trip report, providing an advance indication of whether a destination carries elevated exposure to earthquakes, floods, cyclones, or volcanic activity. Identifying that risk before departure allows travellers to complete the pre-trip preparation that governments recommend — researching local emergency warning systems, locating the nearest British embassy or consulate, identifying evacuation routes, and ensuring travel insurance explicitly covers natural disaster events.

Travellers should check the FCDO country-specific advice for travelling abroad, including the latest information on travel warnings, safety and security, health and entry requirements, and can also check this while away for any updates. Travel advice is kept under constant review to ensure it reflects the latest assessment of risks to British nationals overseas and how to get help in an emergency. Prepare

Step One: Act on the Warning Immediately

When a natural disaster warning is issued — whether delivered via local emergency services, a hotel manager, a tour guide, a government alert system, or an FCDO email alert that reaches your phone — the first step is to act on it immediately, not to assess its severity before deciding whether to respond.

When a natural disaster warning is issued, travellers should find out what is happening, where and when, and do so quickly. Natural disasters can affect phone lines, mobile towers, and the internet, meaning it may become impossible to access information later or act on any new information received. Smartraveller

The window between warning and impact varies dramatically by disaster type. A hurricane warning may give travellers 24 to 48 hours. A tsunami warning may give minutes. An earthquake, by definition, gives no warning at all. The behaviour that saves lives in all of these scenarios is identical: act on the warning as if it is accurate, as if the impact is imminent, and as if the precautionary steps are not optional.

Travellers should find out where the nearest emergency shelter is, have a back-up plan if they cannot get to where they planned to shelter, prepare an emergency supply kit including essential items, charge all devices and battery packs before power is cut off, wear practical clothing and sturdy shoes, and contact family and friends to let them know what is happening. Smartraveller

Step Two: Follow Local Authorities — Not Social Media

Every government emergency framework reviewed for this article — FCDO, Smartraveller, the US ready.gov platform — converges on a single instruction that travellers frequently ignore in practice: follow the guidance of local authorities, not secondary sources. In the information environment of a developing crisis, social media fills rapidly with speculation, misinformation, and unverified reports that can actively direct travellers towards danger rather than away from it.

Travellers in a crisis should take immediate action to stay safe, and if already safe where they are, should not go out or travel until the threat has passed. Local first responders should be followed unless the FCDO specifically advises otherwise. Smartraveller

Travellers are responsible for their own personal safety. They should follow the advice provided by the UK government and local authorities. The FCDO does not have a general duty of care to British nationals abroad. GOV.UK

The FCDO’s If you’re affected by a crisis abroad page is explicit that while the FCDO can provide assistance in large-scale crises, the scale of what is possible depends heavily on the situation. The help the FCDO can provide in a crisis may be limited, particularly in a country where the FCDO already advises against travel, as the FCDO has a duty of care to its own staff and will not send them into a situation where their safety could be seriously at risk. GOV.UK

Step Three: Earthquake-Specific Protocol

For travellers caught in an earthquake — which unlike most natural disasters arrives without warning — the FCDO’s UK Prepare Campaign provides specific physical guidance that diverges from some older assumptions about doorframes and building exits.

In the event of an earthquake, travellers should drop to the ground, cover their head and hold on. If inside a building, they should stay where they are and not go outside or change location, and should avoid sheltering under door frames where possible. If outside, travellers should stay outside and try to stay away from buildings, powerlines, and trees. If near the ocean, they should move to higher ground. If driving, they should pull over and stop where it is safe to do so, ideally away from buildings, powerlines, and trees. Prepare

The instruction to stay inside during shaking — counter-intuitive to many travellers who instinctively move towards exits — reflects the reality that most earthquake injuries in buildings come from falling debris during the movement towards an exit, not from structural collapse itself. After the shaking stops, the immediate priority shifts to tsunami risk for coastal travellers.

In developing countries, the impacts of an earthquake may increase. Poor building regulations and infrastructure may mean buildings and utilities are less able to resist damage, and emergency responders may not have the same level of training or resources as in more developed nations. Smartraveller

Step Four: Tsunami Protocol

A tsunami warning following a coastal earthquake is one of the most time-critical natural disaster scenarios a traveller can face. The Smartraveller and FCDO Prepare Campaign guidance is unambiguous about what is required.

In the event of a tsunami, travellers should get to high ground or inland as soon as possible. They may be alerted through a public announcement or emergency alert sent to their mobile phone. Instructions should be followed immediately. In countries prone to tsunamis, there may be signposted evacuation routes. Travellers should follow these routes where available. They should wait on high ground or inland until told it is safe to return. Sometimes there is no advance warning of a tsunami. If travelling to a coastal region, travellers should know the signs of an incoming tsunami: a sudden rise or fall in sea level, a sudden loud or strange noise from the sea, or feeling a strong earthquake near the sea that makes it hard to stand up. Prepare

Travellers should not wait for tsunami warnings and evacuation orders if they have seen natural signs of an incoming wave. Evacuation routes are often marked by a wave with an arrow in the direction of higher ground. If in the water during a tsunami, travellers should grab onto something that floats, such as a raft or tree trunk. Ready.gov

Step Five: Tropical Cyclone, Hurricane, or Typhoon Protocol

Unlike earthquakes, tropical cyclones offer advance warning — typically days, sometimes hours — but that window is frequently squandered by travellers who underestimate the speed at which conditions deteriorate or who wait for confirmation that the forecast track will hit their specific location.

In the event of a tropical cyclone, travellers should follow local advice, listening to emergency alerts and information issued by local authorities. If asked to evacuate, they should do so as soon as possible and take key documents such as a passport and necessary supplies such as medication. Travellers should make their way to emergency shelters if these are available. If not told to evacuate but in an affected area, they should shelter in place and take refuge in emergency shelters, ensuring key documents and important belongings such as prescribed medications are taken. Prepare

Travellers who plan to leave should do so early. Natural disasters can cause flight cancellations and road closures, and transport options may be in short supply and high demand. Travellers should call their airline if they need to change their flight and should contact their travel insurer. Smartraveller

The Smartraveller guidance on cyclones notes that before going to a tropical coastal destination, travellers should check if it experiences cyclones, find out when cyclone season occurs, and read the travel advice for the destination. Smartraveller The FCDO’s country pages list cyclone season information in the natural disasters section of each relevant destination.

Step Six: Volcanic Eruption Protocol

Volcanic eruption warnings operate on a tiered alert scale maintained by local geological authorities, and different alert levels require different responses. The key distinction for travellers is between an eruption that is forecast but has not yet begun, and one that is already underway.

If an eruption is imminent or has already started, travellers should act quickly: talk to the hotel manager, tour guide, or local authorities, listen to the radio and watch the news, find out the risk to their specific location, find out where the nearest evacuation shelter is, and listen for evacuation orders. If told to evacuate, travellers should do so early. If time permits and it is safe to do so, travellers should consider leaving the area, as volcanic eruptions can cause flight cancellations for many weeks and airlines should be contacted as soon as possible. Travellers are already at risk if they can see the eruption, ash, or flying debris from their location. Smartraveller

Step Seven: Flood Protocol

Floods are among the most common natural disaster risks worldwide and present particular challenges because the hazard can materialise extremely quickly — flash floods in particular — or build over days from monsoon or hurricane rainfall.

If there is a flash flood evacuation warning or water is rising rapidly, travellers should act immediately. If outside, they should get out of low-lying areas and areas with streams and stay away from bridges. If inside, they should move to the highest point in the building they can, avoiding closed-off areas where they may be trapped by rising water, and climbing onto the roof only as a last resort. If trapped in a car, travellers should stay inside and call for help. If water is leaking in, they should get on the roof but should not try to leave the car. Smartraveller

Travellers should not walk, swim, or drive through flood waters, as currents can be strong and dangerous, as little as 30cm of water can sweep a car away, and muddy waters can hide large hazards. They should not cross bridges over fast-moving floodwaters, as fast-moving water can wash a bridge away without warning and may have damaged bridge supports. Smartraveller

Step Eight: Contact Your Embassy, Insurer, and Family

Once immediate physical safety is secured, three communications take priority in parallel: contacting the nearest British embassy or consulate, contacting your travel insurer, and notifying family or emergency contacts of your situation and location.

The FCDO can be reached 24 hours a day on (+44) (0)20 7008 5000. In large-scale crises the FCDO can open a dedicated hotline and online form, open a dedicated online registration service for affected nationals to provide their details and location, share data with other organisations to provide additional support, and send additional FCDO staff to support in-country when it is needed and safe to do so. In exceptional circumstances, where commercial flights are not available, the FCDO may provide additional transport such as a charter flight. GOV.UK

The critical caveat about FCDO assistance in natural disasters is one that many travellers are unaware of: assistance under these measures will not be made available to those who have travelled to a country or region for which the FCDO had advised against all travel immediately prior to the incident. GOV.UK Travellers who proceeded to a destination against active FCDO advice forfeit their entitlement to crisis assistance.

Travellers should contact their loved ones to tell family and friends where and how they are as soon as possible. If family and friends have heard about the crisis from news coverage, they will fear for the traveller’s safety. Travellers should only contact the government emergency centre if they need urgent help or have serious concerns for family or friends abroad, and not for general enquiries. Smartraveller

Step Nine: Do Not Return to Damaged Areas Prematurely

The period immediately after the acute phase of a natural disaster is frequently more dangerous than the event itself, for reasons that are not always obvious to travellers. Aftershocks follow major earthquakes, sometimes for days. Flood waters conceal structural damage to roads and bridges. Post-disaster conditions create rapid secondary disease risks, particularly waterborne illness following flooding.

Travellers should seek help from local authorities first, as emergency services in most destinations have processes in place for natural disasters. If injured, they should get medical care and go to the nearest hospital, which may also have local knowledge about what is happening and advice on staying safe. Smartraveller

Travellers should only leave shelter or return to evacuated areas when authorities say it is safe. Water-borne infectious diseases are common during and after a flood. Travellers should get extra water bottles as they will need clean drinking water. Smartraveller

The FCDO’s natural hazards guidance at gov.uk/guidance/extreme-weather-and-natural-hazards notes that events such as tropical cyclones and earthquakes could trigger other risks such as landslides, aftershocks, or outbreaks of diseases, and airports, transport networks, and hotels may shut down if a hurricane approaches. GOV.UK

The Insurance and Advisory Level Connection

A natural disaster that strikes after you have arrived but before any FCDO advisory change is generally covered under standard travel insurance, subject to your policy terms. However, if the FCDO upgrades its advisory level for your destination in response to the disaster — either during the event or in its immediate aftermath — the rules that govern what cover remains available may change.

The FCDO maintains archived versions of previous travel advice at the National Archives, which may be needed to check or support an insurance claim. GOV.UK In natural disaster situations where claims are disputed on timing grounds, the archived advisory record becomes the documentary evidence for when a warning was formally in place.

Travellers who subscribed to FCDO email alerts before departure will have a timestamped notification in their inbox of any advisory change, providing an independent record of when they received the information. This is a practical reason — beyond the obvious safety one — to ensure alert subscriptions are active before travel to any high-risk destination.

Quick Takeaways

• Act on a natural disaster warning immediately — do not wait for confirmation that the forecast track will affect your specific location before beginning preparations.
• Follow local authority instructions above all other sources of guidance. Local emergency services are the experts on evacuation routes, shelter locations, and current hazard conditions.
• For earthquakes: drop, cover, and hold. Stay inside during shaking. Move to high ground after coastal earthquakes, before any tsunami warning is issued — natural signs such as a sudden sea withdrawal are themselves the warning.
• For tropical cyclones: evacuate early when instructed, before transport infrastructure becomes congested or closed. Contact your airline immediately to explore departure options.
• For floods: never drive through or walk through floodwater. Move to high ground. Do not re-enter evacuated areas until local authorities declare it safe.
• Contact the FCDO 24-hour emergency line on (+44) (0)20 7008 5000, your travel insurer, and your emergency contacts as soon as immediate physical safety is secured.
• FCDO crisis assistance is not available to travellers who proceeded against a “do not travel” advisory. Staying within advisory-compliant destinations protects both your safety and your entitlement to consular help.
• Check Travel Warning Check before booking to identify natural hazard risk for your destination, and subscribe to FCDO email alerts to receive advisory changes in real time throughout your trip.

Frequently Asked Questions

What should I do the moment a natural disaster warning is issued while I am abroad?

Find out what is happening, where and when, and do so quickly. Natural disasters can affect phone lines, mobile towers, and the internet, making it potentially impossible to access information later. Find out where the nearest emergency shelter is, have a back-up plan ready, prepare an emergency supply kit, charge devices and battery packs, and contact family and friends to let them know what is happening. Smartraveller Then follow the specific protocol for the type of disaster — and follow it immediately.

Will the FCDO evacuate me if there is a natural disaster while I am abroad?

The FCDO can set up a specific crisis response to help British nationals, which may include opening a dedicated hotline and online form, an online registration service, and in exceptional circumstances where commercial flights are not available, providing additional transport such as a charter flight. However, this assistance will not be available to those who have travelled to a country for which the FCDO had advised against all travel immediately prior to the incident, and the FCDO has a duty of care to its own staff and will not send them into situations where their safety could be seriously at risk. GOV.UK

How do I contact the FCDO in a natural disaster emergency abroad?

If you need to contact the FCDO urgently or in an emergency, call the nearest British embassy, high commission, or consulate, or the FCDO in the UK on +44 (0)20 7008 5000, selecting the option “Consular services for British nationals.” You will be put through to the 24/7 Consular team in the Consular Contact Centre. GOV.UK

What are the signs of a tsunami if no official warning has been issued?

Travellers should always respond as if a tsunami is coming if they experience any of the following in countries at risk of tsunamis: a sudden rise or fall in sea level, a sudden loud or strange noise from the sea, or feeling a strong earthquake or earthquake tremors near the sea that makes it hard to stand up. When any of these signs are present, travellers should move to high ground or inland immediately without waiting for an official warning. Prepare

How does a natural disaster affect my travel insurance cover?

A natural disaster that strikes after your arrival and before any FCDO advisory change will generally be covered under a standard travel insurance policy, subject to your policy terms. If the FCDO upgrades its advisory level in response to the disaster, coverage rules may change depending on whether you choose to remain or travel to newly affected areas. Previous versions of FCDO travel advice are available on the National Archives website and may be needed to check or support an insurance claim. GOV.UK Maintaining FCDO email alert subscriptions creates a timestamped record of when you received official advisory information, which can support claims where timing is disputed.
