Haiti quake prompted tsunami warning.

After a powerful earthquake hit Haiti early Saturday, the U.S. Tsunami Warning Center initially reported a tsunami threat and warned of waves between three to 10 feet high.

The threat was then rescinded.

A video circulating on social media showed residents of Les Cayes fleeing a flooded street, splashing through murky, knee-deep water, but it wasn’t clear what caused the flooding.

Earthquakes with a magnitude between 6.5 and 7.5 generally do not produce deadly tsunamis, but they can cause a small sea change level close to a quake’s epicenter, according to the United States Geological Survey.
