Santorini, the popular Greek holiday island, is taking emergency measures in response to intense seismic activity.

Schools remain shut and evacuation flights are underway as Greek holiday island Santorini was rattled by earthquakes for the fourth day in a row. A spike in seismic activity has been recorded on the volcanic island in the Aegean Sea since Friday,

Despite dozens of minor earthquakes in recent days, Greek scientists have ruled out a massive earthquake hitting Greece's Santorini island.

Greek officials are warning those on the popular tourist island destination of Santorini to stay alert in the coming days due to increasing seismic activity which could mean a strong earthquake is possible.

More than 200 tremors have been registered since Friday between the volcanic islands of Santorini and Amorgos, the civil protection ministry said in a statement on Sunday, citing experts tasked with assessing earthquake risks and monitoring Greece’s volcanic arc.

The strongest earthquake recorded was magnitude 4.6 at 3:55 p.m. Sunday, at a depth of 14 kilometers (9 miles), the Athens Geodynamic Institute said.

Schools on the Greek island of Santorini have been told to close on Monday in response to an increase in seismic activity in recent days. Authorities have also advised against "large gatherings in enclosed spaces" across the island - a popular tourist destination known for its whitewashed buildings and blue domed churches.

Schools have been closed and emergency crews were deployed on the Greek island of Santorini after a spike in seismic activity raised concerns about a potentially powerful earthquake. Precautions were also ordered on several nearby Aegean Sea islands – all popular summer holiday destinations – after more than 200 undersea earthquakes were recorded in the area over the past three days.

Greece's tourist island of Santorini on Sunday braced for the prospect of more tremors after more than 200 small earthquakes shook the site of one of the largest volcanic eruptions in recorded history,
