The 5.3 magnitude jolt was centered about 75 miles northwest of the Greek capital beneath Amfiklia, a town in the Phthiotis region, according to the European-Mediterranean Seismological Center.
Firefighters moved their equipment outside immediately following the quake at 6:01 p.m. local time.
There were no reports of significant damage or injuries from the shaking, which was preceded by a weaker tremor just a few minutes earlier near the same epicenter.
The Phthiotis region has experienced several moderate quakes over the past two months, including a 5.1 magnitude jolt on Aug. 7 that damaged about 300 buildings.
The damage was not immediately visible, and was only uncovered during inspections several days later.
