Authorities moved more than 47,000 people to shelters in earthquake-hit Tibet, Chinese officials said on Thursday, while rescuers widen a massive combing effort for survivors near the foothills of the Himalayas, despite slim survival odds.

More than 14,000 rescue workers have arrived in Tibet to continue the search for survivors after a strong earthquake killed at least 126 people in a remote part of western China.

Authorities moved more than 45,000 people in earthquake-hit Tibet to shelters in a massive rescue operation at the foot of the Himalayas as they wound down the search in a high-altitude environment where the odds of survival were always slim.
