A moderate earthquake measuring 4.6 on the Richter scale jolted Greece's Samothrace island in the northern Aegean Sea on Tuesday, according to the Geodynamic Institute of the Athens National Observatory.

No casualties or material damage have so far been reported by local authorities.

Greek experts traced the quake's epicenter in the sea area to about 30 kilometers southwest of the island's coast at a depth of approximately 10 kilometers.

Professor Eythymios Lekkas explained that Tuesday's earthquake is linked to the North Anatolian Fault which runs across neighboring Turkey and is one of the most energetic earthquake zones worldwide.

He added that experts expect aftershocks, but reassured that there is no cause for concern for inhabited areas.

Greece and Turkey are two of the most seismic-prone countries worldwide. In the worst most recent catastrophe caused by earthquake in Greece, Athens was rocked by a 6-magnitude tremor in autumn 1999 which left more than 100 people dead and caused extensive material damages.
