ATHENS, Greece (CNN) -- A strong earthquake jolted western Greece on Sunday, killing one person and triggering landslides that have reportedly trapped at least 11 people, according to officials and state-run media.
Another 15 have been injured as a result of the quake, many trying to flee their homes, according to Greece's NET television. It struck around 3:30 p.m. local time and measured 6.1 in magnitude, according to the U.S. Geological Survey. Athens' Geodynamic Institute registered the quake at 6.5 on the Richter scale -- which is no longer used by the USGS.
Greek Interior Minister Prokopis Pavlopoulos has called on assessment and rescue teams to head to the region.
The quake's epicenter was located about 35 km (20 miles) southwest of the Greek port city of Patras in the Peloponnese region. It was "no surprise" that a strong quake hit the region, where earthquakes are common, according to Geodynamic Institute director Gerasimos Papadopoulos.
