At least seven people were injured in Greece on Thursday in a rockfall at the popular Navagio beach in the island of Zakynthos, Greek authorities said.
Also known as "shipwreck beach", the cove is only accessible by sea, and is famous for the wreckage of a small cargo ship that has been washed up on the beach since the '80s.
Video footage of the moment showed the rock split and drop onto the shore, sending up a cloud of dust and speeding waves inland over the assorted tourists.
The coast guard said one foreign woman was injured and was being transported to a local hospital. The woman's husband and two children were hospitalized with minor injuries. O'Connell estimates there are around 400 to 500 people in the area when the rockfall occurred and around a dozen tourist boats were out in the bay. "We heard a sound and a small part of the rock fell, then a second one, and finally a third and large piece dropped in the sea, creating turbulence that overturned the boats", a witness reported. He believed more were coming, so he started running.More news: Sickening discovery in meal costs restaurant chain millions
"We haven't found any trapped people but we will continue searching", a spokesperson for the fire brigade said.
"A giant wave hit the small boats and debris hit people on the beach", she said.
The 21-year-old, who works for a tour company on the island, said: "The rock that fell, oh gosh, it would be like a four storey building falling onto the beach".
