Japan seismic risk profile

This seismic risk profile of Japan, produced by the Global Earthquake Model (GEM) Foundation summarizes key metrics of seismic risk, allowing stakeholders in risk management to get an overview of the risk in the country.

The profile presents the following relevant information:

• Social indicators, which provide context to the region in question;
• Risk indicators, detailing an occupancy breakdown of exposed value and losses;
• A list of the major earthquakes that have impacted the region;
• Loss per region, providing a breakdown of average annual losses per administrative level 1;
• Building classes, depicting the major construction materials used in the region;
• Loss curves, which provide expected losses per different return periods;
• Maps depicting the geographical distribution of hazard, exposure, and losses.

The risk values presented are the results of an event-based risk analysis, where 100,000 years of earthquakes are simulated. Three lines of business are considered: residential, commercial, and industrial. Therefore, the value or earthquake losses from damage to other building occupancies (e.g., schools, healthcare) and infrastructure are not included.
