Schools on the affected islands are entering their third week of closure. As a precaution, authorities have deployed rescue teams and established backup power generation. The Greek government also announced the development of an emergency port facility on Santorini to facilitate a potential large-scale evacuation.

The swarm near Santorini appears to be related to the activation of a system of normal faults, fractures in the Earth’s crust where there is movement. Earthquakes are the result of a sudden release of tension built up by the movement along these faults.

A new cof magnitude 5 on the Richter scale was recorded on Tuesday morning between the Greek islands of Santorini and Amorgos. The earthquake occurred at 4.46 a.m. local time (0246GMT) at a depth of 13 kilometers (8.077 miles), according to the Geodynamics Institute of the National Observatory of Athens.

Geology professor Abraham Zelilidis had argued that seismic activity off Santorini is linked to volcanoes. The University of Patras professor, in a post today, appeared reassuring and said the “risk has diminished”.
