Coast guard and fire brigade officials confirmed that the injuries sustained were not life-threatening.
Seven people including a family of Czech tourists were injured Thursday following a rockslide at Navagio beach on the island of Zakynthos or Zante, one of Greece's most popular travel destinations, officials said.
The video included below shows the moment the rock broke away from the cliff face, with what was described as some as being an "almighty cracking sound".
Video footage uploaded on the website of Greek newspaper Proto Thema showed bathers running in panic as a large part of a cliff peeled off the rockwall and tumbled down at a point close to the sandy shore.
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.
WHAT'S HAPPENING: Florence begins to batter Carolina coast
Hurricane Florence is threatening millions of Americans in the southeast, as FEMA warns that this is a very unsafe storm. North Carolina Governor Roy Cooper predicted tens of thousands of homes and businesses would be flooded in his state.
Authorities were seeking to determine whether there were any people missing. While so far, no one has been found, they said they were continuing their search.
The whole beach is surrounded by steep cliffs and can only be reached by boat.
"A giant wave hit the small boats and debris hit people on the beach", she said.
Another six people, including two children, had received treatment for minor injuries, a hospital official in Zakynthos told Reuters.
