A tsunami is a particularly large wave that occurs as a direct result of geological events, e.g. earthquakes, landslides or volcanic eruptions.
Another word for tsunami is tidal wave.
The Norwegian Natural Perils Insurance Act is being extended from 1 January 2023 to include damage caused by meteorite strikes. The second sentence of the act’s first paragraph will then read:
Natural damage is defined as damage caused directly by a natural disaster in the form of a landslide, avalanche, storm, flood, storm surge, tsunami, meteorite strike, earthquake or volcanic eruption.
