Mitsotakis's remarks come as many people in Santorini spent Sunday night outdoors, amid fears of potential damage to buildings during the quakes. Some focal points of the tremors have been recorded at a depth of just 2km (1.2miles) below the surface.

A series of earthquakes near the Greek island of Santorini have led authorities to shut down schools, dispatch rescue teams with sniffer dogs and sent instructions to residents including a request to drain their swimming pools.

Greek prime minister Kyriakos Mitsotakis has shared news of “a very intense geological phenomenon” ongoing around the popular Greek island of Santorini, urging for “calm” following tremors of up to 4.9 magnitude.
