Multiple earthquakes are rattling Santorini, a volcanic island in Greece, prompting authorities to dispatch rescuers with tents, a sniffer dog and drones, and to shut schools on four islands.

Some locals and travelers are choosing to preemptively evacuate the Greek island of Santorini amidst the spike in seismic activity.

Santorini is famed for its crescent-shaped caldera, which was created by one of the largest known volcanic eruptions around 3,600 years ago. The tourist destination has been dubbed Greece’s “Instagram island” because of its photogenic golden light and sweeping scenery.
