Tsunami Hazard level: Low ?

Tsunamis are large ocean waves generated by sudden displacement of water, most commonly caused by undersea earthquakes, but also by submarine landslides and volcanic eruptions. These waves can travel across ocean basins at high speeds and grow to destructive heights as they approach shallow coastal waters. The severity of tsunami hazard depends on the magnitude of the triggering event, ocean bathymetry, coastal topography, and the presence of natural or built protective features.

In the area you have selected (Guinea-Bissau) tsunami hazard is classified as low according to the information that is currently available. This means that there is approximately 0.04% chance per year of a potentially-damaging tsunami occurring (about 2% chance in the next 50 years). Based on this information, the impact of tsunami may be considered in different phases of the project for any activities located near the coast. Risk studies, project planning decisions, project design, and construction methods may want to take into account the level of tsunami hazard. Further detailed information should be obtained to adequately account for the level of hazard.

Climate change impact: The areas at risk of tsunami will increase as global mean sea level rises. According to the IPCC (2013), global mean sea level rise depends on a variety of factors, and estimates for 2100 range from ~20 cm to nearly 1 m. However, regional changes in sea level are difficult to predict. Projects in low-lying coastal areas such as deltas, or in island states should be designed to be robust to projected increases in global sea level.
