"It is not surprising," he says. "This entire community has been shaken to its core, they are surrounded by unstable buildings which threaten to topple at any moment, and the people have been deeply traumatised by what has happened."
The Chinese government has organised a massive search and rescue effort, which has garnered some success.
On Saturday, several people were dug out of the rubble, including a 52-year-old man who was pulled free after 117 hours buried in debris.
Xinhua also reported that a German tourist was pulled from the rubble - though it later revised its story, saying the mountain climber had not been buried, just cut off by a landslide, and that he made his own way to safety.
Rescue teams from South Korea, Singapore and Russia have joined Japanese and Taiwanese experts taking part in the massive search.
The specialist teams are equipped with sniffer dogs, and fibre-optic cameras and heat sensors to detect people buried under the rubble.
But the number of people being pulled out alive are few and increasingly it is dead bodies which are being retrieved.
BBC reporter at the scene
The authorities have resorted to burying the bodies in mass graves in an effort to prevent disease.
People in the quake zone are being told to wear face masks and disinfectant teams are out in force.
The BBC's Quentin Sommerville in Chengdu says that five days on China's efforts are now squarely focused on getting help to those who survived the earthquake.
Rubble from destroyed buildings is being taken away and streets are being cleared.
In some of the worst hit areas, people now have tents, fresh water, and something to eat. But in more inaccessible parts of the province, the authorities are still struggling to get help to survivors.
Race against time
China's president has urged rescuers throughout the earthquake-struck province of Sichuan to race to save lives.
Visiting the south-western province, Hu Jintao said "time is pressing" during the effort's "most crucial phase".
"Although the time for the best chance of rescue, the first 72 hours after an earthquake, has passed, saving lives remains the top priority of our work," Mr Hu told distraught relatives of those still missing.
