An earthquake swarm near the Greek island of Santorini is gradually declining a month after it began, according to scientists monitoring the phenomenon.

The undersea shocks — sometimes recorded only minutes apart — led thousands of residents and workers to flee the famed clifftop towns of Santorini and the nearby islands of Ios, Amorgos, and Anafi.
