At least seven people were injured on Thursday after part of a cliff overlooking a popular beach in Greece came crashing to the sand.
Authorities of the ports authorities made the decision to protect the safety of thousands of tourists visiting the famous "Shipwreck Beach" each day during peak tourism season.
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".
A Czech woman suffered back injuries and was taken to hospital, another six people, including two children were treated for minor injuries. "They whipped up a whirlpool that overturned (three) boats", an eyewitness told the agency.
While now, no one is missing, the coastguard called in helicopters and boats to search the area, in case anyone was trapped under the rocks.
Officials said that no tourists in the area were reported missing, but air and sea rescue teams were sent to the island-known as Zante in Western Europe-to conduct a search as a precaution in case someone was trapped.
"A giant wave hit the small boats and debris hit people on the beach", she said.
Lynette Bridges, 58, was on a tour boat, pulling up to "Shipwreck Beach" as the incident happened.
