REYKJAVIK, Iceland A strong earthquake shook southern Iceland on Thursday, damaging roads and buildings and causing some injuries, officials and local media said.
Channel 2 television cited civil protection authorities as saying the quake caused injuries, but it was not immediately clear how many.
The U.S. Geological Survey said the magnitude 6.1 quake hit at 3:46 p.m., with its epicenter near the town of Selfoss, 30 miles east-southeast of the capital, Reykjavik. The Icelandic Geological Survey said it measured 6.3 on the Richter scale.
Residents in the capital felt buildings shake.
Iceland's national broadcaster RUV radio reported no injuries but said buildings had been damaged near the epicenter. Authorities advised residents in the area to leave their homes because of the possibility of aftershocks.
The road between Reykjavik and Selfoss was closed by quake damage, RUV said.
Iceland, population 300,000, is a geologically unstable volcanic island in the north Atlantic.
The country's last major earthquake, in June 2000, measured 6.6 on the Richter scale. It knocked down a dozen houses but caused no serious injuries.
