The interactive map provides data for a range of natural hazards, including tsunamis, volcanic eruptions, and earthquakes. Users can select individual hazards to learn more about the date of occurrence, location, severity, economic impact, and social impact.
To do so, we need to understand how disaster events are changing, who is most vulnerable, and what can be done to protect them. On this page, you will find our complete collection of data, charts, and research on natural disasters and their costs.
List of countries by natural disaster risk. Maps of the 2022 WorldRiskIndex and its components. The report systematically considers a country's vulnerability and its exposure to natural hazards to determine a ranking of countries around the world based on their natural disaster risk.
The Global Earthquake Model (GEM) Global Seismic Hazard Map (version 2018.1) depicts the geographic distribution of the Peak Ground Acceleration (PGA) with a 10% probability of being exceeded in 50 years, computed for reference rock conditions (shear wave velocity, VS30, of 760-800 m/s).

Three new maps reveal which parts of the globe are most at risk of earthquakes — and where most people are vulnerable to seismic disaster.
The first map, of global seismic hazard, shows in unprecedented detail which parts of the globe are prone to earthquakes — such as the ‘Ring of Fire’ around the Pacific Ocean (see ‘Modelling earthquake hazard’).
The second, of global seismic risk, highlights areas where buildings are likely to be damaged by the ground shaking, such as Guatemala. The third, of global exposure, looks at the number of buildings around the world — emphasizing the danger in highly populated regions such as Indonesia and India.
The charts, released on 5 December, are the culmination of a years-long international effort coordinated by the Global Earthquake Model (GEM), a non-profit organization in Pavia, Italy, that works with emergency management officials, geological surveys and disaster-preparedness groups worldwide.
GEM expects to update the maps, which are built on an open-source platform, roughly once a year.
The seismic-hazard map is the first major global effort of its kind since 1999, says Marco Pagani, a hazard coordinator at GEM who led the map’s development. It incorporates more than 30 national and regional models from groups such as the US Geological Survey and the China Earthquake Administration. For countries or regions without updated models, GEM worked with local experts to produce them.
