(CNN) -- A strong earthquake struck Tuesday near Greek islands close to the Turkish coast, according to the U.S. Geological Survey.
One person died, police said.
The 6.4-magnitude quake hit about 40 miles (64 km) southwest of the Dodecanese Islands, a series of Greek islands in the Mediterranean Sea closer to the Turkish coast than to the Greek mainland, the survey said.
The quake happened at 6:26 a.m. local time (11:26 p.m. ET).
A 56-year-old woman died after slipping and hitting her head while racing downstairs to get out of her house, according to a police spokesman in Rhodes, a city in the Dodecanese Islands.
Authorities were concerned that another stronger earthquake would occur, Rhodes Mayor Hatzis N. Hatziefthimiou told CNN.
