The tremors are happening at the same time a volcano activity warning was issued by the Climate Crisis and Civil Protection Ministry of Greece after what they described as “mild seismic-volcanic activity” in the caldera on Santorini.
Since Saturday, over 380 tremors have been recorded at magnitudes over 3.0 including as large as 4.9. An expert government committee stressed, however, that the tremors were “not linked to volcanic activity.”
It should be noted that in 2011, there was similar activity that lasted for over a year with no major incidents occurring because of the earthquakes and volcanic activity.
However, because Santorini is a well-known tourist destination, authorities decided to err on the side of caution, while at the same time saying there is no immediate cause for concern.
Despite the statement of “no immediate cause for concern,” schools have been closed and the Greek government has advised people not to attend large events while deploying emergency teams.
With shaking happening every 3 to 4 hours, it has been enough to rattle the calm of many, and airlines are adding flights to accommodate the larger than usual number of people that want to get out of Santorini.
At the request of the Greek Ministry of Climate Crisis and Civil Protection, AEGEAN added two extra flights today and another for tomorrow due to demand, and the Blue Star Chios ferry has been fully booked since this morning.

The US Embassy and Consulate in Greece issued a travel warning alerting US citizens to a series of earthquakes near the Greek islands of Amorgos, Santorini (Thira), Anafi, and Ios.
