The Nice tsunami of 1979 came on October 16. Two

Nice Airport, and an aseismic submarine landslide. The two waves struck the coast between the Italian border and the town of Antibes (60 miles; 96 km).[1] They reached 3 m high near Nice and 3.5 m[2]
at La Salis (Antibes) and decreased in amplitude from there.

Causes

The origin of these events has been a subject of academic and judicial debate.

Nice airport; while the other stated that it was an underwater landslide.[4]

A 0.15 km3[5] slide took place off Nice airport while constructing the fill of the new airport, perhaps as a consequence of this work. This landslide would have caused the first tsunami. The material from this slide could have caused a submarine slide that would have caused the second tsunami.[4]

In the second hypothesis, the major natural submarine landslide (~8.7 km2) that occurred offshore Nice caused a tsunami which would have caused a landslide of the fill of the new airport. This landslide caused another tsunami.[4]

Consequences

Casualty estimates range between 8[2] and 23.[6] At the construction site, the collapsing fill killed seven people.[2]

The tsunamis inundated a 20-mile section of the coast.[7] The water travelled up to 150 m inland.[2] Eleven people were swept away in Nice and one in Antibes.[1] The airport works were finished, but this event forestalled the construction of a new port for Nice.
