An earthquake with preliminary magnitude 4.9 has struck the Greek island of Evia, but there are no reports of damage or injury, officials say.
The Athens Geodynamic Institute says the quake occurred shortly after 8 pm local time, near the town of Istiaia.
It was felt strongly in the Greek capital, about 120 kilometres (75 miles) away.
Greece lies in one of the world's most earthquake-prone zones. Most of the quakes recorded every year cause little damage, but in 1999 a magnitude 5.9 quake killed 143 people in Athens, caused 110 buildings to collapse and severely damaged about 5,000 more.
