A series of earthquakes continues to rattle the sea area south of Amorgos and Santorini in the Cyclades region of Greece. 

Five notable tremors, including one measuring magnitude 5 on the Richter scale, were recorded overnight, according to the Geodynamic Institute of the National Observatory of Athens.

The earthquakes occurred in reverse chronological order at 05:47, 02:02, 00:51, 00:44, and 00:37 local time.  The magnitudes were three of magnitude 4, one 4.1, and the strongest, a magnitude 5.  The epicenters were located in the sea area between 16 and 18 kilometers south of Arkesini, Amorgos.  The magnitude 5 quake at 00:37 is classified as "strong," while the others are classified as "weak."

This follows a 5.2 magnitude tremor on Monday at 22:16, the strongest in the seismic sequence thus far.

Since late last month, a rectangular sea region between the Cyclades islands of Santorini, Amorgos, Ios, and Anafi has experienced over 9,000 earthquakes, including several moderate tremors above magnitude 5. (ILKHA)
