Natural Disaster Preparedness for Young Adults: Earthquakes, Floods, and Extreme Weather

Why Natural Disaster Preparedness Matters for Young Adults

Natural disasters do not discriminate. They affect every part of the world, from the earthquake-prone coastlines of Japan and Chile to the flood plains of Bangladesh and the Netherlands, from the cyclone paths of Australia and the Philippines to the wildfire corridors of California and Portugal. For young adults living independently for the first time, often in unfamiliar cities and without the immediate support network of family nearby, the ability to prepare for and respond to natural disasters is a genuinely life-saving skill.

The statistics are sobering. According to the United Nations Office for Disaster Risk Reduction, natural disasters affected more than 400 million people globally in 2023 alone. Climate change is increasing the frequency and intensity of many types of extreme weather events, meaning that disasters once considered rare are becoming more common in regions that had previously experienced them infrequently. Understanding how to protect yourself before, during, and after a natural disaster is not alarmist preparation for an unlikely scenario. It is practical, responsible self-care for the world we live in.

This guide focuses on three of the most widespread and dangerous natural hazard types: earthquakes, floods, and extreme weather events including storms, heatwaves, and wildfires. For each, we cover what to expect, how to prepare, and how to respond.

Earthquakes: Preparation and Response

Earthquakes occur along tectonic fault lines found on every continent, but they are particularly common in regions known as seismic zones. The Pacific Ring of Fire, which encompasses Japan, New Zealand, the west coast of the Americas, and the Philippines, is the most seismically active region on Earth. But earthquakes also occur regularly in parts of Europe, Central Asia, the Middle East, and South Asia. If you live in or plan to visit any of these regions, earthquake preparedness is directly relevant to you.

The key to surviving an earthquake is preparation before one occurs. In your home, identify potential hazards and take steps to reduce them. Heavy items on high shelves can become deadly projectiles during violent shaking. Secure bookcases, wardrobes, and filing cabinets to walls. Keep heavy objects and glass items at low heights where possible. Know where the structural safe zones in your building are, typically underneath sturdy tables or against interior walls, and know where the exits are.

Prepare an emergency kit and keep it somewhere accessible. It should contain at minimum: three days' worth of water (approximately three litres per person per day), non-perishable food, a torch with spare batteries or a wind-up torch, a first aid kit, copies of important documents in a waterproof bag, a whistle, a dust mask, and any essential medications. In earthquake-prone regions, many emergency services recommend having a 72-hour kit, which is enough to sustain you for the three days that emergency responders typically take to reach all affected areas following a major quake.

When an earthquake strikes, the standard advice used in many countries is Drop, Cover, and Hold On. Drop to your hands and knees to prevent being knocked over by the shaking. Take cover under a sturdy table or desk if one is nearby, or if not, cover your head and neck with your arms. Hold on until the shaking stops. If you are outdoors, move away from buildings, power lines, and anything that could fall on you. If you are in a vehicle, slow down gradually and pull over away from bridges, overpasses, and buildings, then remain inside with your seatbelt fastened until the shaking stops.

After an earthquake, check yourself and others for injuries before assessing the building. Be aware that aftershocks frequently follow the initial event and can be powerful enough to cause additional damage, particularly to structures already weakened by the initial quake. Do not use lifts. Be cautious of gas leaks, which can cause explosions, and broken glass underfoot. If you smell gas, leave the building immediately and report it to the relevant emergency service.

Familiarise yourself with the tsunami warning procedures in coastal areas, as many major earthquakes in coastal regions generate tsunamis. If you are near a coast and feel strong ground shaking, or receive an official warning, move inland and to higher ground immediately without waiting for official confirmation.

Floods: Understanding the Risk and Staying Safe

Flooding is the most common natural disaster globally. It can occur as a result of prolonged heavy rainfall, rapid snowmelt, storm surges, dam failures, or a combination of these factors. Unlike earthquakes, floods often develop over a period of hours or days, which means there is frequently more opportunity to prepare and evacuate if you are paying attention to warnings.

Understanding your flood risk is the first step. Many countries maintain flood risk maps that are available online. The Environment Agency in England, the Federal Emergency Management Agency in the United States, and equivalent bodies in most countries provide free access to information about whether a particular address is in a flood zone. If you are renting a property, find out whether it has ever flooded before and whether it is in a designated flood risk area. This information is particularly important when choosing where to live.

If you live in an area at risk of flooding, take practical steps to protect your home and possessions. Keep important documents, electronics, and irreplaceable items stored at height. Consider keeping sandbags or temporary flood barriers available if you are in a high-risk zone. Know how to turn off the gas, electricity, and water supply to your property in the event of an emergency.

Monitor weather forecasts and flood warnings during periods of heavy rain. In the UK, the Environment Agency provides a free flood warning service by phone and text. In Australia, the Bureau of Meteorology issues flood watches and warnings. Most countries have equivalent systems, and signing up for alerts relevant to your area can give you critical time to act.

When a flood warning is issued, do not wait until floodwater is at your door before acting. If an evacuation order has been issued by local authorities, follow it without delay. Take your emergency kit, important documents, medications, and your phone charger. Let someone outside the affected area know where you are going. Drive only if necessary, and never attempt to drive through floodwater. Just 30 centimetres of moving water can knock an adult off their feet, and 60 centimetres is enough to carry away a car. Floodwater frequently conceals washed-away road surfaces, open manholes, and other hazards that make it genuinely dangerous to walk through.

After a flood, do not return to your home until authorities confirm it is safe to do so. When you do return, be aware of structural damage, contaminated water, and the presence of wildlife such as snakes that may have sought shelter inside buildings during the flood. Wear protective clothing when cleaning up floodwater, which is frequently contaminated with sewage and chemicals.

Extreme Weather: Storms, Heatwaves, and Wildfires

Extreme weather events cover a broad range of hazards, and the specific types you are most likely to encounter depend heavily on where you live. However, three types have become increasingly relevant globally as a result of climate change: severe storms (including cyclones, hurricanes, and typhoons), heatwaves, and wildfires.

Severe storms, known as hurricanes in the Atlantic, typhoons in the Pacific, and cyclones in the Indian Ocean and Southern Pacific, are among the most powerful and destructive weather events on Earth. If you live in or travel to regions affected by these storms, understanding the warning system and having a clear plan is essential. Most affected countries use numbered or lettered warning systems that indicate the expected severity and timing of an approaching storm. When a warning is issued, secure loose objects outside your home, stock up on supplies, charge your devices, and be ready to evacuate if instructed to do so.

Heatwaves are the deadliest type of weather extreme in many countries, particularly in Europe. The 2003 European heatwave killed an estimated 70,000 people. The heatwaves of subsequent years have claimed thousands more lives across every continent. For young adults, heatwaves may seem less threatening than dramatic storm events, but they deserve equal seriousness. During a heatwave, stay hydrated by drinking water regularly even if you do not feel thirsty. Avoid vigorous physical activity during the hottest part of the day, typically between 11am and 3pm. Stay in the coolest part of your home or access public air-conditioned spaces if your home has no cooling. Check on elderly neighbours and relatives, who are among the most vulnerable to heat-related illness. Know the signs of heat exhaustion and heatstroke: heavy sweating, dizziness, nausea, rapid heartbeat, and in severe cases, confusion and loss of consciousness. Heatstroke is a medical emergency requiring immediate professional attention.

Wildfires have become a significant and growing threat in many regions where they were previously rare, including parts of Europe such as Greece and Portugal, as well as in Australia, parts of North America, and South Africa. If you live in or are visiting an area at risk of wildfires, stay alert to fire danger ratings issued by local authorities and fire services. These ratings indicate the level of risk on any given day based on temperature, humidity, and wind conditions. Avoid lighting fires, including barbecues, on high or extreme fire danger days. If a wildfire is approaching your area, follow any evacuation orders immediately. Attempting to defend a property from a wildfire without professional training and equipment is extremely dangerous and has claimed many lives. Prepare a go-bag in advance so that you can leave quickly if necessary.

Building Your Emergency Kit

Regardless of the specific type of disaster most relevant to your location, every young adult living independently should have a basic emergency kit assembled and accessible. The kit does not need to be elaborate or expensive. The goal is to ensure that you can sustain yourself for at least 72 hours without access to shops, running water, or electricity.

A well-prepared emergency kit should include: at least three litres of water per person per day for three days, either in sealed bottles or a portable filtration system; non-perishable food items such as tinned goods, dried fruit, nuts, and energy bars; a manual tin opener; a first aid kit with bandages, antiseptic, and any personal medications; a wind-up or battery-powered torch; spare batteries; a portable phone charger or power bank; a whistle for signalling; waterproof copies of essential documents including your passport, insurance details, and emergency contacts; a basic map of your local area; and warm clothing and a blanket.

Review and update your emergency kit every six months, replacing any food or water that has expired and checking that batteries are still functional. Store the kit in an easily accessible location that all members of your household know about.

Creating a Personal Emergency Plan

An emergency kit is only one component of effective disaster preparedness. Having a clear personal emergency plan is equally important, particularly for young adults who may be living in a city they are unfamiliar with, far from family, or in shared accommodation with people who have different plans.

Your emergency plan should include: a designated meeting point with housemates or local friends if you are separated during a disaster; the contact details of an out-of-area friend or family member who can act as a central contact point, as local phone networks are often congested following a disaster; a clear understanding of your building's evacuation routes and assembly points; knowledge of the location of the nearest emergency shelter or official evacuation point in your area; and an understanding of how your local authority communicates emergency warnings, whether through apps, sirens, or broadcast media.

Share your plan with the people closest to you. An emergency plan is only effective if everyone who needs to know about it does. In shared accommodation in particular, taking 30 minutes to discuss these basics with housemates can make a significant difference in a real emergency.

Staying Informed and Connected

One of the most important things you can do in the lead-up to a disaster, and during the recovery period, is to stay informed through reliable sources. Follow your local emergency management agency on social media and sign up for any alert systems available in your area. In moments of crisis, misinformation spreads rapidly on social platforms, and distinguishing between official guidance and rumour is a critical skill.

Keep a battery-powered or wind-up radio available, as it can provide access to emergency broadcasts even when power and internet services are down. Know the emergency frequency for your area in advance, rather than searching for it during a crisis.

Natural disasters are unpredictable, but your response to them does not have to be. The young adults who come through major disaster events most safely are not those who are lucky, but those who have prepared thoughtfully, stayed informed, and acted decisively when the situation required it.
