Repeated earthquakes are rattling Greece’s volcanic island of Santorini. The quakes are prompting authorities to dispatch rescuers with tents, a sniffer dog and drones and to shut down schools on four islands.

Schools on the Greek island of Santorini have been forced to close after reports of "seismic activity". Tremors reaching up to 4.9 in magnitude were recorded northeast of the island on Monday, with recent days also seeing quakes of 4.3 and 3.9 magnitude reported in the vicinity.

Greek Prime Minister Kyriakos Mitsotakis has urged people on the island of Santorini to "stay calm" after an increase in seismic activity. His remarks come as schools were told to close on Monday and authorities advised against large gatherings in enclosed spaces across the island,
