Aftershocks threaten swollen China 'quake lake'*

Chengdu, China (AFP) June 10, 2008
Powerful aftershocks continued to threaten the stability of a swollen
"quake lake" in southwest China Monday, amid urgent efforts to drain its
rising waters to prevent a flood downstream.
A 5.0-magnitude aftershock rattled the area of quake-devastated Sichuan
province where the lake is located on Monday, US seismologists reported.
An aftershock of the same strength struck the region on Sunday.
A local official in the city of Mianyang, not far from the Tangjiashan
lake, said the aftershocks had so far not affected the unstable body of
water.
But state-run Xinhua news agency said Sunday's tremor had caused
"massive landslides" on nearby mountains, and state television said
Monday that the situation remained "highly dangerous," with hundreds of
thousands of people living downstream.
The lake has become one of the most pressing issues in the aftermath of
the May 12 quake that struck mountainous Sichuan, killing 69,142 and
leaving 17,551 others missing, according to the latest toll issued Monday.
Millions more have been left homeless by the 8.0-magnitude quake, which
triggered huge landslides that blocked rivers and created more than 30
unstable "quake lakes," including the Tangjiashan one on the Jianjiang
river.
Soldiers were rushing Monday to clear a third channel to drain water
from the lake, the state-run China Daily reported, in a race against
time to reduce the risk that it might burst its banks.
Troops began draining water through one hastily dug channel on Saturday
to stop the lake from emptying all at once.
"Yesterday's (Sunday) rain and aftershock disrupted our work, but we are
working against time to make up for it," Xu Qiangguo, an officer with
the police's hydropower force, was quoted by Xinhua as saying.
The water resources ministry said Monday the water level had risen by
nearly one metre (three feet) in a 24-hour period -- double the rate of
the water flowing out through the drainage channels.
About 6,900 cubic metres of water -- the equivalent of nearly three
Olympic-sized swimming pools -- were flowing into the lake every minute,
the ministry said.
Troops working at the lake triggered 10 explosions on Monday to
accelerate drainage, but only 3,000 cubic metres of water were now
flowing out every minute, Xinhua reported.
Torrential rain was forecast for much of southern China over the next
few days, but was not expected to affect quake-hit areas of Sichuan, the
country's meteorological centre said.
The quake zone was however due to see searing hot temperatures --
unwelcome news for the millions of displaced people living in tents.
Heatstroke and related ailments are bringing increasing numbers of
people from the makeshift refugee camps to a field hospital in
quake-ravaged Dujiangyan.
"This could be a very big problem as the weather gets hotter," said Zou
Hejian, who heads the medical staff at the temporary facility.
Premier Wen Jiabao warned Monday there could be no let up as epidemic
prevention work remained a tough task in the quake zone, Xinhua reported.
At a quake relief meeting in Beijing, Wen also urged greater efforts to
treat the injured to minimise fatalities and disability, it said.
The government also urged coal mines to "take effective measures" to
increase output, Xinhua said Monday, as parts of the country run low
following the quake. It said mines forced to close for safety should
strive to resume operations as soon as possible.
China's coal industry has been under stress due to shortages this year,
a situation worsened by the May 12 quake, which damaged a "considerable"
number of hydropower stations, Xinhua said.
Meanwhile, 15 local officials in Sichuan have been dismissed from their
posts because they engaged in malpractice in quake relief efforts,
Xinhua said late Monday.
The officials were blamed for malfeasance related to the relief efforts,
as well as for responding slowly to the disaster, Xinhua said, citing
the organisation department of the Communist Party of China's provincial
committee.
