Thousands of residents of the southeastern Spanish city of Lorca slept outside Wednesday night, hours after the city of about 80,000 was struck by an earthquake that killed eight people, state radio reported, citing authorities.
    "It was a strange sensation," said a press office worker who was in his office in the regional capital of Murcia, about 60 kilometers from Lorca. He estimated the duration of the quake from five to eight seconds.
    The 5.1-magnitude quake occurred at 6:47 p.m. and was centered about 50 kilometers southwest of Murcia, near the Mediterranean coast, the U.S. Geological Survey said.
    It was preceded at 5:05 p.m. by a 4.5-magnitude temblor centered in the same area, the survey said. At least one of the deaths occurred in a building collapse in Lorca, state-run EFE said.
    The press office said a hospital in Lorca had been evacuated as a precaution.
    Many of those who were spending the night outside said they were afraid to return to their houses or had been advised not to do so, state radio said.
