How to anticipate and react to natural risks?
In the face of various natural phenomena such as storms, floods, or earthquakes, it is essential to be well-prepared. While it is difficult to predict natural hazards, it is possible to limit risks and damage by adopting the right actions.
Are you exposed to natural hazards?
In anticipation of natural risks, it is crucial to understand the different hazards one may be exposed to and assess personal vulnerability. Phenomena such as storms and hail, floods, storms, wildfires, heatwaves, and snow—especially if you live in mountainous areas—are potentially devastating natural events.
To assess your exposure to these risks, it is recommended to consult resources such as Géorisques, the reference site for major natural and technological risks. It provides detailed information on flood zones, areas likely to experience storms, and other geological hazards. By locating yourself on the map, you can get a complete description of the risks identified for your municipality, preventive information documents, and specific details about local risks such as floods, landslides, earthquakes, or industrial sites.

Getting informed about risks
The next step is to stay informed about present or potential natural risks. This is essential for proper preparation. Météo France provides accurate weather forecasts that help anticipate extreme weather conditions. A real-time weather alert map is available on their website.
Additionally, radios, televisions, and SMS are effective channels for receiving emergency alerts. Social media, while less official, can also provide real-time information.
There are also specific alerts issued by local authorities, such as during Storm Ciaran in October 2023. Several prefectures sent out notifications via cellular broadcasting. This doesn't require the internet and can be received on phones in airplane mode.
Lastly, the sirens of the National Alert Network (RNA) are another important means of warning the population in the event of imminent danger.
Proper Preparation is Key
This is undoubtedly the most important step, one not to be overlooked. Proper preparation for natural risks involves several key measures. The first is to create a family emergency plan (PFMS). The PFMS is a document that lists the risks you face, the instructions to follow, emergency contact numbers, and family procedures. It provides clear instructions for each family member in case of evacuation or confinement.
Moreover, an emergency kit or evacuation bag should be prepared in advance. The government recommends a kit that supports a minimum of 72 hours of self-sufficiency. It should contain essential supplies like non-perishable food, water, medications, spare clothes, and various small items such as a charger, cash, a multitool, a flashlight, etc

Here is an example of equipment to include in your 72-hour emergency kit :
Petzl e+Lite Headlamp: Compact, lightweight, and designed for emergency situations by the French brand Petzl.
Waterproof and windproof matches: These storm matches are far more effective than regular matches.
Rechargeable radio with USB port, dynamo, or solar power: Perfect for staying updated on the situation during a disaster.
Victorinox Huntsman Swiss Knife: This tool combines 15 functions in 1: can opener, blade, wood saw, scissors, etc.
Sunslice Emperion 65 Fast Charger: With a 65-watt power output, it can quickly charge up to 3 devices simultaneously.
For food and water, there are several types of meals with long shelf lives.
First, there are freeze-dried pouches. They are useful for evacuation, as their packaging is compact and lightweight, making them easy to carry. With a shelf life of 3 to 8 years, simply rehydrate them to consume.
Second, there are canned meals with a shelf life of 25 years. These complete, nutritious meals also rehydrate with hot or cold water, allowing you to enjoy a complete, varied, and nutritious meal.
Third, food rations are easy to transport and especially useful in case of evacuation. MREs (Meals Ready-to-Eat) are popular since they are self-heating. These are the types of rations used by the U.S. military.
For water, there are water sachets with a shelf life of 5 years, resistant to heat, cold, and even freezing.
Finally, to conclude the preparation section, ensure all important documents (ID cards, prescriptions, etc.) are protected, either by storing them in a secure place or by digitizing them to prevent loss in case of a disaster
Protect Yourself When the Time Comes
In case of an alert, follow the instructions from the authorities and avoid any unnecessary movement. Depending on the nature of the natural disaster, secure your home by cutting off potentially dangerous energy sources, barricading windows and doors, or storing objects that could become projectiles, such as garden furniture or trash bins. Avoid making phone calls to prevent overloading the lines, and only call in case of emergency. Also, consider those around you, ensuring that your neighbors, especially the most vulnerable, are well protected. Above all, stay calm! With good preparation, as mentioned earlier, the risks will be greatly minimized.
Our Tips for Dealing with Natural Disasters
Reacting to an Earthquake
- Before: Secure your bookshelves and appliances to the wall. Store porcelain and heavy items on the lowest shelves. Secure items that could fall during an earthquake using putty or bubble wrap.
- During: During an earthquake, drop to the ground. Take shelter under a sturdy table or desk. Hold on tightly.
- After: If there is damage to your house, go shut off the gas and electricity to prevent a fire. Move carefully and cautiously to avoid debris, and take your insurance documents with you
Reacting to a Fire
- Before: Prevention is key. Be cautious with candles, matches, and electrical appliances. Regularly check smoke detectors. In areas near forests, create a defensible space around your home (density of surrounding trees, clean roofs and gutters, trim branches to two meters, store firewood away from the house, water the lawn, etc.).
- During: When the smoke detector sounds, get low, stay away from the smoke, and exit quickly. Call 18. Do not stay inside to fight the fire or try to save your belongings.
- After: Treat any injuries or smoke inhalation and file your insurance claims
Reacting to a Flood
- Before: During heavy rainfall, all areas can become prone to flooding, including plains. Build accordingly and plan for easy access to supplies (food and water).
- During: Follow all evacuation orders but never cross flooded areas. Go to the upper floor of your house or building.
- After: Be cautious of debris in the water. Monitor for mold in areas damaged by flooding, and keep track of your insurance documents
Reacting to a storm
- Before: Secure windows and doors. Bring in outdoor furniture and potential projectiles. Also, make sure you have a battery and a manual radio.
- During: Follow all evacuation plans. Stay indoors, away from windows. Stay informed through emergency radios.After: If there has been damage to your house, turn off the gas and electricity to prevent a fire. Move cautiously and safely, and take your insurance documents with you.
