A new travel warning has been issued by the Foreign Office after seismic activity has been detected.

Travel advice was issued for Santorini and Amorgos following increased seismic activity.

The update came on Saturday and warns British travellers of an increased issue for earthquake activity.

Seismic activity has intensified in the areas, with dozens of small tremors recorded in Santorini, Amorgos, and the surrounding islands.

An earthquake struck at 12:16pm, registering a magnitude of 3.9 on the Richter scale, according to Greek media.

The tremor occurred 25 km north-northwest of Anafi, with a focal depth of 15 km.

Aftershocks have been frequent, with minor tremors ranging between 2 and 3 on the Richter scale.

Shortly after, another earthquake of 3.1 magnitude was recorded 18 km south-southeast of Arkesini, Amorgos.

Earlier on Saturday morning, weak tremors were reported within minutes of each other in Amorgos and Santorini.

Santorini Volcano was also the site of one of largest volcanic eruptions in human history, which took place in the Bronze Age around 1620 BC, destroying a large part of the island and giving Santorini its current shape. 

The eruption is believed to have contributed to the decline of the ancient Minoan civilization which had flourished in the region.

Although it is still an active volcano, the last notable eruption occurred in 1950.

Speaking to state broadcaster ERT today, seismologist Gerasimos Papadopoulos assured the public that there is no cause for alarm.

He said: “There have indeed been many earthquakes, especially over the past week. Since early January, but particularly this past week, we have recorded over 150 to 200 tremors. 

“Only a few have occurred directly on the island of Santorini. Most of them are located northeast, about 10 to 30 kilometers away.”
