The U.S. Geological Survey says a 6.1-magnitude earthquake struck Greece just before 3:30 pm local time, or 7:30 am central time, on Sunday
The earthquake was centered about 20 miles southwest of Patras, Greece or 125 miles west of Athens at a depth of just 6 miles.
Severe shaking was felt just northeast of the town Amalias, where moderate to heavy damage was sustained.
CNN reports that at least two people were killed, and several people were trapped beneath buildings that collapsed in the earthquake. Most of those known to be trapped have been removed. At least 37 people were injured.
Greece is highly prone to large earthquakes because it lies on an active seismic fault line.
