Soon after the quake hit, the BBC's Michael Bristow said a local sports stadium had been turned into a refugee centre and was the scene of emotional family reunions:
"We witnessed a very, very moving scene when a man was desperately trying to reach his 18-year-old daughter on the telephone. He hadn't seen her since the earthquake. In fact, the daughter didn't know her family were alive and we've just seen them meet for the first time since the earthquake. Everyone was very overcome and crying."
