Data for the visualization published on the OD Mekong Disasters and emergency response page (https://opendevelopmentmekong.net/topics/disasters-and-emergency-response/). It shows the number of total deaths recorded by natural disaster classification. Source: EM-DAT: The OFDA/CRED International Disaster Database – www.emdat.be – Université Catholique de Louvain – Brussels – Belgium
In 2023, there was a total of 398 natural disasters events recorded worldwide, down from 398 recorded a year earlier. The Europe, Middle East and Africa region experienced the highest number of natural disasters that year. Deaths and costs of natural disasters Natural disasters affect almost every part of the world. In February 2023, Turkey and Syria were hit by earthquakes that resulted in the highest number of deaths due to natural disaster events that year. In terms of economic damage, Hurricane Katrina remains one of the most expensive natural disasters in the world, topped only by the earthquake/tsunami which hit Japan in 2011. Climate change and natural disasters Climate change has influenced the prevalence of natural disasters. Global warming can increase the risk of extreme weather, resulting in higher risk of droughts and stronger storms, such as tropical cyclones. For instance, higher levels of water vapor in the atmosphere give storms the power to emerge. Furthermore, the heat in the atmosphere and high ocean surface temperatures lead to increased wind speeds, which characterize tropical storms. Areas that are usually unaffected by the sea are becoming more vulnerable due to rising sea levels as waves and currents become stronger.

The Canadian Disaster Database is a publicly accessible web-based repository of historical information about natural and man-made disasters that have taken place since 1900 in Canada or abroad that have directly affected Canadians. The database contains information on over 1000 events and can be used to support research, academic activities and decision-making across a breadth of fields including earth sciences, agriculture, climate change, biology and epidemiology, land use planning, insurance, investment, and the anthropological and sociological aspects of community resilience, among many others. Canada endeavours to provide the best information possible; however, the information contained in the Canadian Disaster Database (CDD) is based on information that is sourced from outside parties and may not be accurate. Canada makes no representations, warranties, or guarantees, express or implied, that the data contained in the CDD may be relied upon for any use whatsoever. Canada accepts no responsibility or liability for inaccuracies, errors or omissions in the data and any loss, damage or costs incurred as a result of using or relying on the data in any way. The CDD may contain material that is subject to licensing requirements or copyright restrictions and may not be reproduced, published, distributed or transferred in whole or in part without the consent of the author. The CDD shares information on events that have fully concluded to ensure that the data reflects the event appropriately (i.e., insurance and disaster recovery payment information is available). For this reason, events for which the costs and/or other impacts have not fully recorded contributes to a delay in making them available through the CDD.

The Geocoded Disasters (GDIS) Dataset is a geocoded extension of a selection of natural disasters from the Centre for Research on the Epidemiology of Disasters' (CRED) Emergency Events Database (EM-DAT). The data set encompasses 39,953 locations for 9,924 disasters that occurred worldwide in the years 1960 to 2018. All floods, storms (typhoons, monsoons etc.), earthquakes, landslides, droughts, volcanic activity and extreme temperatures that were recorded in EM-DAT during these 58 years and could be geocoded are included in the data set. The highest spatial resolution in the data set corresponds to administrative level 3 (usually district/commune/village) in the Global Administrative Areas database (GADM, 2018). The vast majority of the locations are administrative level 1 (typically state/province/region).
In 2024, there were roughly 18,100 reported fatalities caused by natural disaster events worldwide. This was well below the 21st-century average and significantly lower than the fatalities recorded in 2023, which were driven by the earthquakes that hit Turkey and Syria on February and became the deadliest catastrophes in 2023, with nearly 60,000 reported deaths. Economic losses due to natural disasters The economic losses due to natural disaster events worldwide amounted to about 368 billion U.S. dollars in 2024. Although figures in recent years have remained mostly stable, 2011 remains the costliest year to date. Among the different types of natural disaster events, tropical cyclones caused the largest economic losses across the globe in 2024. What does a natural disaster cost? Hurricane Katrina has been one of the costliest disasters in the world, costing the insurance industry some 102 billion U.S. dollars. The resilience of societies against catastrophes have been boosted by insurance industry payouts. Nevertheless, insurance payouts are primarily garnered by industrialized countries. In emerging and developing regions, disaster insurance coverage is still limited, despite the need for improved risk management and resilience as a method to mitigate the impact of disasters and to promote sustainable growth.
"Disaster data for countries along the belt and road, mainly from the global disaster database.The records information of disaster database are from the United Nations, government and non-governmental organizations, research institutions and the media. It's documented in detail such as the country where the disaster occurred, the type of disaster, the date of the disaster, the number of deaths and the estimated economic losses. This study extracts the natural disaster records of the countries along the One Belt And One Road line one by one from the database, and finally forms the disaster database of 9 major disasters of the 65 countries. The natural disaster records collected can be roughly divided into nine categories, including: floods, landslides, extreme temperatures, storms, droughts, forest fires, earthquakes, mass movements and volcanic activities. From 1900 to 2018, a total of 5,479 disaster records were recorded in countries along the One Belt And One Road. From 2000 to 2015, there were 2,673 disaster records. On this basis, the natural disasters of the countries along the belt and road are investigated from four aspects, including disaster frequency, death toll, disaster-affected population and economic loss assessment. Overall, since 1900, a total of 5479 natural disasters have occurred in countries along the One Belt And One Road, resulting in about 19 million deaths and economic losses of about 950 billion us dollars. Among them, the most frequent occurrence is flood and storm; the biggest economic losses are floods and earthquakes; the most affected people are flood and drought; drought and flooding are the leading causes of death
In 2023, the United States experienced 25 natural disasters, which made it the most natural catastrophe-prone country in the world that year. India and China came second on that list with 17 natural disasters occurring in the same year. Floods was the most common type of natural disaster in 2023. Types of natural disasters There are many different types of natural disasters that occur worldwide, including earthquakes, droughts, storms, floods, volcanic activity, extreme temperatures, landslides, and wild fires. Overall, there were 398 natural disasters registered all over the world in 2023. Costs of natural disasters Due to their destructive nature, natural disasters take a severe toll on populations and countries. Storms and floods, which tend to occur most regularly, have the biggest economic impact in the countries that they occur. In 2023, storms caused damages estimated at more than 100 billion U.S. dollars. Meanwhile, the number of deaths due to natural disasters neared 100,000 that year. The earthquake in Turkey in February had the highest death toll, with more than 50,000 fatalities. Scientists predict that some natural disasters such as storms, floods, landslides, and wildfires will be more frequent and more intense in the future, creating both human and financial losses.
Record disasters such as earthquakes, hurricanes (or typhoons), tsunamis, widespread flooding and pollution, droughts, extremes of snowfalls and temperatures - all of which are associated with devastating losses and suffering - occur almost daily. Out of all natural disasters, floods in coastal regions are regarded as one of the most dangerous and harmful. According to the International Disaster Database (EM-DAT) such floods have shown the fastest rate of increase relative to other types of disasters (see also CRED 2004 and CRED 2011). However, most of these events, although commonly referred to as natural disasters, are not in fact the results of nature-related processes alone. They are to an ever increasing extent directly attributable to various social, economic, historical, political and even cultural issues. Rapid urbanization in coastal areas combined with climate change and poor governance can lead to a significant increase in the risk of local surface flooding (pluvial) coinciding with high water levels in rivers (fluvial) and high tide or storm surges from the sea (coastal) posing a greater risk of devastation in coastal communities. A particularly important part of the management of complex problems such as disasters due to extreme hydro-meteorological events is to understand the hazards formation over a range of spatial and temporal scales. For these purpose state of the art science and technology are used for better comprehension of the extreme events formation in today¿s climate and future changing climate conditions.

Archival records contain numerous references to climatic disasters or natural events, long before legislation took up the issue of compensation for victims of public or agricultural calamities.
The dataset made available here is a list of dated and localised events, compiled from information disseminated in inventories of the National Archives.
It contains the following information:
This dataset does not claim to be an exhaustive record of events over a period. It aims to make available dated and localised facts, in order to promote the exploitation of other content (press archives, documents kept in public archives, etc.). For example, for the 1950s and 1960s, only events were retained for which there is a file with several pieces. Chronological files containing prefectural orders classifying municipalities in a state of public disaster have not been identified; foot-and-mouth disease epizootic diseases, endemic during these years, have also not been taken into account.
The data made available concern (as of 20 November 2023) the recount of two groups of files:
This dataset is expected to be updated later with other recounts.
The Act of 13 July 1982 on compensation to victims of natural disasters amends the previous legislation amending the previous regulatory regime (Law No 48-1516 of 26 September 1948, amended by Law No 50-960 of 8 August 1950, Act of 4 August 1956 establishing a fund for the relief of victims of disasters and disasters, Act of 10 July 1964 on agricultural disasters). The “paper” records of the recognition of the state of natural disaster resulting from the 1982 Act are archived in the National Archives. The data are available in open data via the database “Aided Management of Administrative Risk Procedures (GASPAR)](https://www.data.gouv.fr/fr/datasets/base-nationale-de-gestion-assistee-des-procedures-administratives-relatives-aux-risques-gaspar/#/resources)”.

This database is a collection of data over 23,000 US earthquakes. It contains data from the year 1638 to 1985. The digital database also includes information regarding epicentral coordinates, magnitudes, focal depths, names and coordinates of reporting cities (or localities), reported intensities, and the distance from the city (or locality) to the epicenter. The majority of felt reports are from the US but there is information about also some other countries such as Antigua and Barbuda, Canada, Mexico, Panama, and the Philippines.
Year Mo Da Hr Mn Sec The Date and Time are listed in Universal Coordinated Time and are Year, Month (Mo), Day (Da), Hour (Hr), Minute (Mn), Second (Sec)
UTC Conv Number of hours to subtract from the Date and Time given in Universal Coordinated Time to get local standard time for the epicenter. In general: 4 = 60 degree meridian (Atlantic Standard Time) 5 = 75 degree meridian (Eastern Standard Time) 6 = 90 degree meridian (Central Standard Time) 7 = 105 degree meridian (Mountain Standard Time) 8 = 120 degree meridian (Pacific Standard Time) 9 = 135 degree meridian (Alaska Standard Time) 10 = 150 degree meridian (Hawaii-Aleutian Standard Time)
U/G Unpublished or grouped intensity U = Intensity (MMI) assigned that was not listed in the source document. G = Intensity grouped I-III in the source document was reassigned intensity III.
EQ Lat / EQ Long This is the geographic latitude and longitude of the epicenter expressed as decimal numbers. The units are degrees. The latitude range is +4.0 to +69.0, where "+" designates North latitude (there are no South latitudes in the database). The longitude range is -179.0 to +180.0, where "-" designates West longitude and "+" designates East longitude. Most of the epicenters are West longitude (from -56 to -179), but a few epicenters in the Philippines and Aleutian Islands are East longitude (from +120 to +180).
Mag These are magnitudes as listed in United States Earthquakes, Earthquake History of the United States (either mb, MS, or ML), or the equivalent derived from intensities for pre-instrumental events. The magnitude is a measure of seismic energy. The magnitude scale is logarithmic. An increase of one in magnitude represents a tenfold increase in the recorded wave amplitude. However, the energy release associated with an increase of one in magnitude is not tenfold, but thirtyfold. For example, approximately 900 times more energy is released in an earthquake of magnitude 7 than in an earthquake of magnitude 5. Each increase in magnitude of one unit is equivalent to an increase of seismic energy of about 1,600,000,000,000 ergs.
Depth (km) Hypocentral Depth (positive downward) in kilometers from the surface.
Epi Dis Epicentral Distance in km that the reporting city (or locality) is located from the epicenter of the earthquake.
City Lat / City Long This is the geographic latitude and longitude of the city (or locality) where the Modified Mercalli Intensity was observed, expressed as decimal numbers. The units are degrees. The latitude range is +6.0 to +72.0, where "+" designates North latitude (there are no South latitudes in the database). The longitude range is -177.0 to +180.0, where "-" designates West longitude and "+" designates East longitude. Most of the reporting cities (or localities) are West longitude (from -29 to -177), but a few reporting cities (or localities) in the Philippines and Aleutian Islands are East longitude (from +119 to +180).
MMI Modified Mercalli Scale Intensity (MMI) is given in Roman Numerals. Values range from I to XII. (Roman Numerals were converted to numbers in the digital database. Values range from 1 to 12.) Macroseismic information is compiled from various sources including newspaper articles, foreign broadcasts, U.S. Geological Survey Earthquake reports and seismological station reports.

The HANZE dataset covers riverine, pluvial, coastal and compound floods that have occurred in 42 European countries between 1870 and 2020. The data was collected by extensive data-collection from more than 800 sources ranging from news reports through government databases to scientific papers. The dataset includes 2521 events characterized by at least one impact statistic: area inundated, fatalities, persons affected or economic loss. Economic losses are presented both in the original currencies and price levels as well as inflation and exchange-rate adjusted to 2020 value of the euro. The spatial footprint of affected areas is consistently recorded using more than 1400 subnational units corresponding, with minor exceptions, to the European Union’s Nomenclature of Territorial Units for Statistics (NUTS), level 3. Daily start and end dates, information on causes of the event, notes on data quality issues or associated non-flood impacts, and full bibliography of each record supplement the dataset. Apart from the possibility to download the data, the database can be viewed, filtered and visualized online: https://naturalhazards.eu. The dataset is designed to be complimentary to HANZE-Exposure, a high-resolution model of historical exposure changes (such as population and asset value), and be easily usable in statistical and spatial analyses.
The dataset contains the following files (CSV comma-delimited, UTF8, and ESRI shapefiles in zipped folders)

This database contains summary information on 168 Canadian flood disasters that occurred between 1900 and June 1997. The database is not, by sany means, a complete list of flood events in Canada since the vast majority of the floods did not cause disasters. All mentions of damage costs have not been corrected for inflation. The database also is biased towards the more densely populated areas of Canada where floods are more likely to impact humans.
