A 5.4-magnitude tremor occurred early Sunday in the Aegean Sea, near the small Greek island of Nisyros, west of Rhodes, the Athens-based Institute of Geodynamics reported.
The quake’s epicenter was 23 kilometers (14.3 miles) south southwest of Nisyros, a small island, round in shape with about 1,000 inhabitants and an active volcano. The tremor occurred at 7:31 a.m. local time (0431 GMT) at a depth 15.6 kilometers (9.7 miles), the institute reported.
Geologists cannot yet say whether this series of earthquakes is related to the active volcano of Nisyros.
The earthquakes were felt throughout southern Aegean, including Crete and the tourist islands of Rhodes and Kos. There are no reports of damage or casualties, Greek state television (ERT) reported.
Since then, several aftershocks have occurred. There are no reports of injuries or damage.
