About 80,000 people were evacuated Tuesday from downstream of an unstable earthquake-created dam that is threatening to collapse, and troops rushed to carve a trench to drain the water before it floods the valley.
The threat of flooding from dozens of lakes swelling behind walls of mud and rubble that have plugged narrow valleys in parts of the disaster zone is adding a new worry for millions of survivors.
More than 30 villages were emptied and the people were being sent to camps like the one outside Jiangyou, where an Associated Press reporter saw 12-15 people crammed into each of about 40 government-issued tents pitched on a hillside overlooking the river.
The magnitude-7.9 quake that struck Sichuan province May 12 sent a mass of dirt and rocks tumbling in the valley about two miles above the town in a spot not reached by roads, plugging a river that is now forming the lake.
Elsewhere in the region, workers also used explosives to level some buildings that were left teetering by the quake — a further sign that officials have stopped rescue and recovery efforts in some places.
The number of deaths from the quake climbed toward an expected toll of 80,000 or more. China’s Cabinet said Tuesday that 67,183 people were confirmed killed, with 20,790 still missing.
Aftershocks continued to rattle the region, causing more damage and injuries and jangling the already-frayed nerves of survivors. Two temblors Tuesday caused more than 420,000 houses to collapse in Qingchuan county, Xinhua reported. Sixty-three people were injured, including six who were critically hurt.
At Tangjiashan lake, hundreds of troops were working around the clock to dig a channel that would divert the rising waters before they breach the top of the rubble wall. Officials fear the loose soil and debris wall could crumble easily if the water starts cascading over the top, and send a torrent flooding down into the valley.
About 5 million people were left homeless by the quake, and many are living in tents or makeshift camps clustered throughout the disaster zone.
Qi Xiaoqiu, the director of disease prevention at the Health Ministry, said the quake had knocked out much of the region’s health infrastructure. He said 12 field hospitals had been erected and tens of thousands of health professionals sent into the zone.
“With the destruction by the quake, the living and sanitary conditions have worsened for the local population,” Qi said in Beijing. “Their physical conditions are weakened, (they are) more vulnerable to disease.”
Diseases such as tuberculosis, hepatitis and diarrhea remained a threat, but so far no outbreaks had been reported, he said.
