Mini-tsunami hurls tourists against rocks on Spanish holiday beach

At least eight people, including children, were injured in Spain on Wednesday when a massive wave crashed onto Mazagon Beach. Mazagon is a picturesque coastal village in the province of Huelva that attracts many holidaymakers.

A video shows the scene where the wave hits a large rock and then crashes back onto the sand.

Witnesses reported that the wave literally knocked people to the ground. One woman, for example, was caught in the wave as she was coming out of the water and fell to the ground. "I was coming out of the water on a paddleboard when the wave hit me from the left and knocked me to the ground," she told the Daily Mail .

He continued: "I couldn't see anything and was trapped under the board. It wasn't until I got to the hospital that I learned what had happened and that a ship was responsible."

Following the incident, people posted on social media that the wave passed very close to the shore and caught several beachgoers, some of whom were thrown against rocks.

The wave is believed to have been caused by the maneuvers of a 60,000-ton cargo ship, the Daily Mail reports.

Local authorities are investigating whether the vessel violated regulations governing distance from the coast and permitted speed. A speed limit of 11.5 knots has already been introduced for such vessels in the area to prevent similar incidents.

There was also excitement on a beach in Portugal this week. A rare weather phenomenon caused panic among tourists on Portugal's northern and central coast, according to " Today ." A so-called roll cloud moved across the sky toward the coast and looked like a giant tidal wave.

Roll clouds ("volutus"), as reported by " The Portugal News ," are horizontal, tubular clouds that often move independently of other cloud formations. They form when cold and warm air collide, as in thunderstorms or cold fronts. Their special shape is created by wind stratification, which also gives the mysterious cloud its rolling motion.
