A 2.9-magnitude earthquake jolted Athens at 3:53 PM local time on Monday. The quake was felt throughout the region of Attica.
According to the National Observatory of Athens, the epicenter was around 10 km (6 miles) northeast of the Greek capital at a focal depth of 5 km into the earth.
There are no reports of damage so far.
Greece is especially earthquake prone
Greece lies in a highly seismically active region. The vast majority of earthquakes cause no damage or injuries, however.
A powerful earthquake measuring 6.3 struck the seabed south of Crete earlier in October.
The quake had a focal depth of 8.2 km (5.09 miles), and its epicenter was southeast of the city of Ierapetra.
The country is located in a complex geological boundary zone in the eastern Mediterranean between the African Plate and the Eurasian Plate.
The northern part of Greece lies on the Eurasian Plate while the southern part lies on the Aegean Sea Plate.
The Aegean Sea Plate is moving southwestward with respect to the Eurasian Plate at about 30 mm (1 inch) per year while the African Plate is subducting northward, beneath the Aegean Sea Plate, at a rate of about 40 mm (1.6 inches) per year.
The northern plate boundary is a relatively diffuse divergent boundary while the southern convergent boundary forms the Hellenic Arc.
