How Many People Die in Natural Disasters Every Year?
Natural disasters kill around 60,000 people a year on average, but single events can kill 200,000. The data on earthquakes, floods, storms and drought.
Picture a coastal town on a calm Sunday morning just after Christmas. Families are on the beach. Fishermen are mending nets. Then the sea pulls back, far further than anyone has seen it go, leaving fish flapping on the exposed sand. People walk out to look. A few minutes later, the water comes back as a wall.
That was the Indian Ocean on 26 December 2004. The earthquake off Sumatra and the tsunami that followed killed around 227,000 people in 14 countries in a single day. It remains one of the deadliest natural disasters of the modern era.
Disasters like that define how we think about nature's death toll. But they are rare. The real story of disaster deaths is one of enormous swings, a steep long-term decline, and a handful of hazards that kill far more people than the headlines suggest.
The headline number
The main global record of disasters is EM-DAT, the international disaster database run by the Centre for Research on the Epidemiology of Disasters (CRED) in Belgium. Over the last two decades, it records an average of roughly 60,000 deaths a year from natural disasters.
That works out to around 165 deaths a day, although of course disasters do not kill evenly. Most years see far fewer, and a single catastrophic event can push one year above 200,000.
| Time period | Natural disaster deaths (long-run average, approx.) |
|---|---|
| Per year | 60,000 |
| Per month | 5,000 |
| Per week | 1,150 |
| Per day | 165 |
| Per hour | 7 |
Against around 62 million deaths a year from all causes, which you can watch in real time on our live death counter, natural disasters account for only about 0.1% of global deaths in an average year. That share is small, but it hides how concentrated, sudden and traumatic these deaths are.
Year by year: a series of spikes
Annual disaster deaths jump around more than almost any other cause of death. This table uses EM-DAT and CRED figures, rounded.
| Year | Approx. deaths | Main events |
|---|---|---|
| 2004 | ~240,000 | Indian Ocean earthquake and tsunami |
| 2008 | ~235,000 | Cyclone Nargis (Myanmar), Sichuan earthquake (China) |
| 2010 | ~300,000 | Haiti earthquake, Russian heatwave |
| 2015 | ~23,000 | Nepal earthquake, heatwaves in India and Europe |
| 2020 | ~15,000 | Floods and storms, no single mega-disaster |
| 2023 | ~86,000 | Turkey and Syria earthquakes, Libya floods |
| 2024 | ~17,000 | Floods, storms and heat, no single mega-disaster |
In a quiet year, around 10,000 to 20,000 people die. In a catastrophic year, it can be ten or twenty times that. The long-run average is pulled up almost entirely by a few huge earthquakes, tsunamis and cyclones.
Which disasters kill the most
Different hazards behave very differently. Floods and storms happen constantly but usually kill fewer people per event. Earthquakes are rarer but far deadlier when they strike populated areas.
| Disaster type | How it kills | Share of deaths in a typical decade |
|---|---|---|
| Earthquakes and tsunamis | Building collapse, waves | Largest single share in most recent decades |
| Extreme temperature | Heatwaves, cold spells | Large and badly undercounted |
| Storms (cyclones, hurricanes) | Storm surge, flooding, wind | Large, falling thanks to warnings |
| Floods | Drowning, disease after | Most frequent disaster type |
| Drought | Famine, disease | Historically the deadliest; now rarely counted directly |
| Landslides | Burial | Smaller, local |
| Volcanoes | Ash, pyroclastic flows | Small in recent decades |
| Wildfires | Burns, smoke | Small directly, larger through smoke |
Earthquakes deserve a special mention because they are the one hazard where warning systems help least. Nobody can yet predict a large quake with useful precision, so survival depends almost entirely on whether buildings stay standing. You can follow live earthquake activity around the world on our earthquake tracker.
Heat is the hidden giant. In EM-DAT, a heatwave counts only if it is reported as a disaster, which is why major European heatwaves sometimes appear and sometimes do not. Modelled estimates put global heat deaths at hundreds of thousands a year, which would make it the deadliest natural hazard by far if it were fully counted. We cover this in how many people die in heatwaves.
The great decline
Here is the part of the story most people never hear. Disaster deaths have fallen enormously over the last century, even as the world's population has quadrupled.
| Decade | Approx. average annual disaster deaths |
|---|---|
| 1920s | ~500,000 or more |
| 1930s | Very high (Chinese floods of 1931) |
| 1960s | ~200,000 to 300,000 |
| 1980s | ~100,000 |
| 2000s | ~80,000 |
| 2010s | ~45,000 |
These figures come from long-run compilations of EM-DAT and historical data, and the early decades are especially uncertain. The trend, though, is clear: deaths per year have fallen by roughly 90% over a hundred years. Per person, the decline is even steeper.
Much of the early toll came from drought and famine. Famines in China, India and the Soviet Union in the first half of the 20th century killed millions. Drought still happens, but it rarely turns into mass famine now, thanks to food trade, aid and early warning systems. Where famine still occurs today, it is usually tied to conflict, as we explain in how many people die from hunger every day.
Why disasters kill fewer people now
The hazards themselves have not changed much. Earthquakes are not weaker; cyclones are not gentler. What has changed is how prepared people are.
| Reason | Example |
|---|---|
| Early warning systems | Cyclone warnings and evacuation in Bangladesh |
| Shelters | Thousands of cyclone shelters along the Bay of Bengal |
| Better buildings | Earthquake codes in Japan, Chile and New Zealand |
| Faster rescue and aid | International response, satellite mapping |
| Food security | Drought no longer automatically means famine |
| Forecasting | Weather models now give days of warning for storms |
Bangladesh is the clearest example. The Bhola cyclone of 1970 killed somewhere between 300,000 and 500,000 people. A cyclone of comparable strength in 1991 killed around 138,000. Since then, after decades of investment in shelters, warnings and evacuation, major cyclones have typically killed in the hundreds or low thousands. The storms are just as strong. The death toll is not.
Rich countries, poor countries
Disasters do not kill fairly. A large earthquake in Japan or Chile might kill dozens or hundreds of people. A quake of similar strength near a crowded city with weak buildings can kill tens of thousands.
| Comparison | Outcome |
|---|---|
| Chile earthquake, 2010 (magnitude 8.8) | Around 500 deaths |
| Haiti earthquake, 2010 (magnitude 7.0) | Over 100,000 deaths; estimates range far higher |
| Japan, Tohoku 2011 (magnitude 9.0) | Around 18,000 deaths, mainly from the tsunami |
| Turkey and Syria, 2023 (magnitude 7.8) | Over 55,000 deaths |
The Haiti earthquake released a fraction of the energy of the Chilean quake that struck a few weeks later, yet killed hundreds of times more people. The difference was buildings and poverty. Most disaster deaths fall on low and middle income countries, which you can explore through our Asia region and Americas region pages, or on the Haiti and Turkey country pages.
Floods: the most common disaster
If earthquakes are the deadliest disaster per event, floods are the most frequent. In most years, floods make up around 40% of all disasters recorded in EM-DAT, and they affect more people than any other hazard, often tens of millions in a single year across South Asia, China and Africa.
| Flood fact | Detail |
|---|---|
| Share of recorded disasters | Around 40% in a typical year |
| Main way floods kill | Drowning, often in vehicles or while crossing water |
| Deaths after the water recedes | Diarrhoeal disease and cholera from contaminated water |
| Most affected regions | South Asia, China, West and East Africa |
| Deadliest recent example | Libya, 2023: dam failures near Derna killed thousands |
Floods kill twice. First come the drownings, often of people caught by surprise at night or trying to drive through moving water: just 30 centimetres of fast-flowing water can float a car. Then, in poorer countries, come the diseases, when floodwater mixes with sewage and contaminates drinking supplies. Those later deaths are often not counted as disaster deaths at all, but they show up in the figures for diarrhoeal disease, which we explore in how many people die from diarrhoea every day.
The Derna floods in Libya show how a disaster can be partly man-made. Storm Daniel brought extreme rainfall, but most of the deaths came when two ageing dams above the city burst and sent a wall of water through neighbourhoods built in the valley below.
Disasters and climate
Is climate change making disasters deadlier? The honest answer is mixed.
| Trend | What the evidence shows |
|---|---|
| Number of recorded disasters | Rising, partly because reporting has improved |
| Heatwaves | More frequent and more intense; heat deaths rising |
| Heavy rainfall and flooding | More intense in many regions |
| Economic losses | Rising sharply as more property sits in harm's way |
| Deaths per year | Still far lower than a century ago |
Better preparation is still outrunning worsening hazards for most disaster types. Heat is the main exception, where deaths are clearly rising, especially among the elderly. Floods and storms are becoming more intense, but warnings and shelters have so far kept deaths from rising with them.
How disaster deaths compare with everyday causes
Disasters dominate the news because they are sudden and dramatic. But they kill far fewer people than the everyday causes that never make headlines.
| Cause | Approx. deaths per year |
|---|---|
| Cardiovascular disease | 18,600,000 |
| Road injuries | 1,190,000 |
| Air pollution | Millions a year |
| Drowning | Around 300,000 |
| Natural disasters (average) | Around 60,000 |
Drowning alone kills several times more people every year than all natural disasters combined, and many disaster deaths are themselves drownings. We cover that in how many people drown every day. For a look at the very worst events on record, see the deadliest natural disasters in history.
While you were reading this
You have spent about 12 minutes with this article. In an average year, natural disasters kill one or two people in that time, although on the day of a major earthquake or cyclone the number can be thousands.
Across all causes, roughly 1,400 people have died worldwide in the same 12 minutes. Most of them died of heart disease, cancer and stroke, quietly, in homes and hospitals. You can watch the total on our live death counter and see today's running figures on the deaths today page.
The headlines will always go to the earthquake. The bigger story is how many lives the world has learned to save from them.
Data sources: EM-DAT, the International Disaster Database, Centre for Research on the Epidemiology of Disasters (CRED), UCLouvain, and its annual "Disasters in numbers" reports; Our World in Data compilations of long-run disaster deaths; World Health Organization. Figures are rounded and approximate; death tolls for individual disasters are often disputed, particularly for older events and for Haiti 2010. Heatwave deaths are only partly captured in EM-DAT.
