Our planet is dynamic, something which has many advantages and a few drawbacks. Some of the latter are the earthquakes and tsunamis caused by the dynamics of the crust.

To deal with them, Principia has analysed the seismic hazard and the response to seismic vibrations in hundreds of sites worldwide and for all types facilities: civil works like bridges and dams, petrochemical installations such as refineries and LNG tanks, nuclear structures, etc.

Tsunamis originate when a large shallow earthquake causes a significant vertical discontinuity in the sea bottom. Principia has also studied this hazard in regions like the Spanish coastline, Algeria, Peru, the Caribbean or the Andaman Islands, and has analysed its consequences.
