Repository with the inventory of residential, commercial and industrial buildings in North Asia Products North Asia Exposure Repository with the inventory of residential, commercial and industrial buildings in North Asia Share Facebook LinkedIn Description The Global Exposure Model is a mosaic of local and regional models with information regarding the residential, commercial, and industrial building stock at the smallest available administrative division of each country and includes details about the number of buildings, number of occupants, vulnerability characteristics, average built-up area, and average replacement cost. The dataset is developed and maintained by the GEM Foundation, using a bottom-up approach at the global scale, using national statistics, socio-economic data, and local datasets. This model allows the identification of the most common types of construction worldwide, regions with large fractions of informal construction, and areas prone to natural disasters with a high concentration of population and building stock.

Contact Us | Global Earthquake Model Foundation CONTACT US The GEM Foundation (Global Earthquake Model) is located in the university town of Pavia, Italy, and is part of the Pavia Risk Centre - a knowledge-hub of organisations, people and institutions working on ‘understanding and managing risk’. The GEM Secretariat is hosted by the EUCENTRE - one of GEM's sponsors and core institutions of the Pavia Risk Centre. Map Directions Message us Share Facebook LinkedIn Medieval Tower, Pavia, Italy Anchor 1 From the airport There are three international airports close to Pavia: Milan Linate - 50km, Milan Malpensa - 90km and Orio al Serio (Bergamo) -100km. Linate Airport There is no direct connection between Linate airport and the GEM Secretariat or Pavia Centre. A taxi from Linate to Pavia will cost around €100.

A single ticket costs €11 and the train takes about an hour to arrive. From there you can take the green metro line to Milan Central Station. ** From Milan Central Station there are trains going to Pavia (timetables can be found on the Trenitalia website). From the Central Station of Pavia take the bus to the GEM Secretariat - see below. Taking the bus to Milan Central Station (right outside both Malpensa Terminal 1 and 2). There are buses almost every 15 minutes during the day, operated by Malpensa Shuttle or Autostradale; the cost of a single ticket is €10. It takes about 45 minutes from Terminal 1, 35 minutes from Terminal 2. From there, follow the route as described above ** A taxi from Malpensa to Pavia centre / the GEM Secretariat will cost around €165. Further information can be found on the Malpensa/Linate website. Orio al Serio Airport (Bergamo) There is no direct connection between the airport of Orio al Serio and Pavia. A taxi from Orio al Serio to Pavia will cost around €175. The fastest way to reach the GEM Secretariat is to take a bus to Milan Central Station (regular services are operated by both Orio Shuttle and Autostradale, a ticket costs around €10) and from there take a train to Pavia.

A classification scheme for the vulnerability attributes of buildings Products GEM Building Taxonomy A classification scheme for the vulnerability attributes of buildings Share Facebook LinkedIn Description The GEM Building Taxonomy is a uniform classification scheme - a method to describe and categorise buildings in the same way across the globe as a key step towards assessing their vulnerability and risk. The current version (v4.0.1) has been used in the development of the v2026 Global Exposure Model. A tool has been developed to help users to quickly validate and understand the classification of buildings according to the GEM Building Taxonomy. It ensures that buildings are correctly categorised, providing explanations for each classification and helping users meet global standards in building classification.

One of the first steps towards this objective has been the open-source development and release of software for seismic hazard and risk assessment called the OpenQuake Engine. This software comprises a set of calculators capable of computing human or economic losses for a collection of assets, caused by a given scenario event, or by considering the probability of all possible events that might happen within a region within a certain time span. Since its initial release in 2010, the OpenQuake engine remains as one of the most important products released by the GEM Foundation, and it has become the benchmark software for seismic hazard and risk calculations worldwide.
