The earthquake risk
in Costa Rica is more
significant than the
hurricane risk.
Annual Average Loss
(AAL) from earthquakes is
US$ 407.5M (0.82% of GDP) and from
hurricanes is US$ 0.25M (0.001% of GDP).
The Probable Maximum
Loss for earthquakes (250
year return period) is US$ 9.7B (20% of GDP)and for hurricanes (250
year return period) is US$ 22.6M (0.05% of GDP).
Single-family, residential
houses constructed with
reinforced masonry bearing
walls are the buildings most
vulnerable to earthquakes, accounting for over 70% of AAL.
Snapshot
Two representations of earthquake risk
Absolute Risk: The larger the circle, the higher the Annual Average Losses that the province could potentially incur over the long term.
Relative Risk: The darker the color, the higher the ratio of AAL/Province Exposure. The darkest color represents the province of Guanacaste which has a higher proportion of vulnerable structures due to construction types and/or potentially higher earthquake intensity.

What is at risk in Costa Rica?Economic assets such as residential and non-residential buildings are at risk. These assets that are exposed to natural disasters are referred to as a country’s Building Exposure.
The map illustrates the value and distribution of residential and non-residential buildings in Costa Rica at risk from earthquakes and hurricanes.
What are the potential losses in Costa Rica? These charts show the estimated potential future losses to Costa Rica that could be caused by earthquakes and hurricanes that could occur within a given return period. In 1910, a magnitude 6.5 earthquake struck Costa Rica. If this historical event were to happen in 2015, it would cause losses of US$ 3,800M, amounting to 8% of GDP.
How can earthquake risk be reduced?
Masonry structures are the most prevalent building types in Costa Rica, accounting for over 80% of AAL. Adobe structures, however, are the riskiest construction types.
