The schools of the Greek island of Santorini have been invited to close Monday following an increase in seismic activity in recent days.
The authorities have also advised “large rallies in closed spaces” through the island – a popular tourist destination known for its lime bleached buildings and blue dome churches.
Tremors measuring up to 4.6 have been recorded in the past two days – with earthquakes of 4.3 and 3.9 magnitude reported nearby Sunday morning.
Santorini is on what is called the Hellenic volcanic arc, but the last major eruption was in 1950. The Greek authorities said that recent movements are not linked to volcanic activity and began to calm down.
The tremors recorded by geologists are considered minor or light, but the authorities have recommended a certain number of preventive measures in addition to the school closure, in particular to avoid the ports of Ammoudi and Fira.
Large cruise ships often anchor near the old port of Fira, with passengers brought to the ground on small boats.
One of the largest volcanic eruptions in history, around 1600 BC, trained the island as it is today.
