China officials rush to evacuate 80,000
MIANYANG, China (AP) - May 27, 2008 The official Xinhua News Agency reported emergency workers would
try to complete the evacuation by midnight Tuesday, taking the
number of people moved out of the threatened valley to almost
160,000, from more than 30 townships.
The Tangjiashan lake in northern Sichuan province, formed when a
massive landslide blocked a river, is one of dozens of fragile dams
created during the earthquake that pose a new destructive threat in
the disaster zone.
Soldiers hauled explosives through the mountains to reach the
area, and the official Chinese Daily said Tuesday on its Web site
they were "preparing to dynamite the barrier." State television
showed live footage of heavy earth-moving equipment being used to
carve out a 200-yard channel to drain the water.
The lake is swelling behind a landslide near Beichuan, one of
the towns hit hardest by the May 12 tremor that devastated Sichuan.
Residents of Huangshi village said they were told to move to a
government-built tent camp on a hillside overlooking the river near
Jiangyou town, southeast of Beichuan, to avoid the potential flood.
"We were told that so far it is the safest place for us to stay
if the dam of the lake crashes," villager Liu Yuhua said Tuesday.
"But we will have to move further uphill if the situation turns
out to be worse."
The number of deaths from the quake has climbed further toward
an expected toll of 80,000 or more. The Cabinet said Tuesday that
67,183 people were confirmed killed - up by about 2,000 from a day
earlier - and 20,790 still were missing.
Elsewhere in the disaster zone, explosives were used to demolish
some damaged buildings in the town of Yingxiu. Teams have been
pulling down creaky buildings across Sichuan recently, using mostly
excavators, bulldozers and other heavy machinery.
Aftershocks continued to rattle the region, including two
temblors Tuesday afternoon that caused more than 420,000 houses to
collapse in Qingchuan county, Xinhua reported. Additional details
were not available about how the estimate was made. Phones were not
answered late Tuesday at the Qingchuan county police department.
Sixty-three people were injured, including six who were
critically hurt.
The U.S. Geological Survey measured a 5.2 magnitude aftershock
that struck just after 4 p.m., followed by a magnitude 5.7 temblor
about a half-hour later.
Dozens of aftershocks have further frayed survivors' nerves. A
major temblor Sunday knocked down thousands of buildings that had
survived the initial quake, and killed eight people.
One quake expert said that aftershocks in the area could
continue for several months, though they would grow weaker as time
passes.
"Judging from previous earthquakes of a similar magnitude, this
time the aftershocks may last for two or three months," He
Yongnian, a former deputy director of China Seismological Bureau,
was quoted as saying by Xinhua.
Some 5 million people were left homeless by the quake, and many
of them are living in tents or makeshift communities that are
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, but 12 field hospitals had been put up and
tens of thousands of health professionals were working in the zone.
"With the destruction by the quake, the living and sanitary
conditions have worsened for the local population," Qi told
reporters in Beijing. "Their physical conditions are weakened (and
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.
About 1,800 soldiers clambered up mountain paths to reach
Tangjiashan with plans to dig and blast their way through the
debris and drain the water, Xinhua reported. It did not say when
the blasting operation would take place.
The Tangjiashan lake is the biggest of about 35 lakes created
when the magnitude 7.9 quake sent millions of tons of earth and
rock tumbling into some of the region's narrow valleys. Some rising
floodwaters have already swallowed villages.
Tangjiashan now holds 34 billion gallons of water and was rising
by more than three feet every 24 hours, Liu said.
Xinhua said troops blasted several tree trunks with explosives
on Tuesday to help clear rubble and were working around the clock
to remove at least 1.8 million cubic feet of debris to build the
channel, which would not be completed before June 5.
Pressure is building behind the dams as rivers and streams feed
into the newly formed lakes. Officials fear the loose soil and
debris walls of the dams could crumble easily, especially once the
water level reaches the top and begins cascading over.
Adding to the threat, thunderstorms were forecast for parts of
Sichuan this week - a foretaste of the coming summer rainy season
that accounts for more than 70 percent of the two feet of rain that
falls on the area each year.
Also in northern Sichuan in Qingchuan county, 1,300 people have
been evacuated from Guanzhuang because of landslide worries. Local
official Li Guoping said plans were being drawn up to evacuate all
23,000 people in the area if needed.
He said landslides that blocked rivers had formed 10 lakes, but
only three had the potential to be dangerous if there were heavy
rains.
"I worry about the start of the rainy season," Li said.
