The strongest earthquake yet after days of near-constant tremors has been recorded near the island of Santorini, the famous Greek tourist haven now almost emptied of visitors and residents.

A strong earthquake has been recorded between the Greek islands of Amorgos and Santorini, after days of consecutive tremors in the area. More than 11,000 people have already left Santorini with around 7,000 departing by ferry and 4,000 people leaving by air.

Hundreds more people were expected to leave Greece's Santorini island on Wednesday as tremors shook the popular summer tourist destination for a sixth day.
