BEIJING (AFP) –
Rescuers rushed to find victims buried by twin shallow earthquakes in
northwest China Monday after the double tremors killed 73 people and
injured more than 400, officials said.
The government of Dingxi
city in Gansu province, which was hit by quakes with magnitudes of 5.9
and 5.6, gave the figures on a verified social media account.
“More
than 21,000 buildings were severely damaged and more than 1,200 have
collapsed,” an official at the provincial earthquake bureau told AFP,
adding that 371 aftershocks had been recorded.
The tremor set off
landslides which buried often crudely constructed local houses, state
broadcaster CCTV reported.
Pictures from the scene showed simple
buildings reduced to rubble, with the pieces of corrugated metal
scattered over the wreckage.
In one location 12 people were
buried, the broadcaster quoted a witness as saying. “The rescue work is
tough, because the house has been completely buried,” the man said.
More
than 2,000 soldiers, 300 police, 50 medical staff and two helicopters
had been sent to the area, the official Xinhua news agency said.
“We
are rushing to the scene,” Dingxi’s vice-mayor told CCTV, which showed
an orange-suited rescue worker riding on a tractor.
“The damage to
houses made from earth bricks has been severe and many are now
unusable,” the official said, adding that the number of people buried by
the quake was still being estimated.
More than 700 rescue workers
had arrived at the scene, CCTV said.
The US Geological Survey
said the initial 5.9-magnitude quake hit at 7:45 am (2345 GMT Sunday) at
a depth of just 9.8 kilometres.
A second 5.6-magnitude tremor hit
the same region at 9:12 am and was 10.1 kilometres deep, USGS said.
A
resident of Min county told AFP he was at work at a medicine production
plant when the tremor struck and he saw tower blocks shake
“ferociously”.
“I was in the workshop. I felt violent shaking and
so I ran to the yard of the plant immediately,” said the man, surnamed
Ma.
“Our factory is only one floor. When I came to the yard, I saw
an 18 storey building, the tallest in our county, shaking ferociously,
especially the 18th floor.”
While Gansu is one of China’s more
sparsely populated provinces, Dingxi city, which includes the worst-hit
counties, has a population of about 2.7 million.
Pictures
broadcast on state television showed rural villages with rubble-strewn
streets.
A total of 380 buildings collapsed and thousands were
damaged in Zhang county, according to an online post by the Dingxi local
government. Communications were cut off in 13 towns in the county, the
official Xinhua news agency said, and power was off in some areas.
The
quake was felt in the provincial capital Lanzhou and as far away as
Xian, the capital of the neighbouring province of Shaanxi, Xinhua
reported.
People posting on China’s hugely popular microblogs
expressed sympathy for the victims. “I hope the dead will rest in
peace,” read one typical remark.
Beijing’s own China Earthquake
Networks Centre put the magnitude of the larger quake at 6.6, Xinhua
added.
The China Earthquake Administration said the same fault
zone was linked to a magnitude 8.0 quake on July 21, 1654, it reported.
The
USGS rated Monday’s main tremor at seven on its “shakemap”, with
shaking perceived to be “very strong” and the potential to cause
“moderate” damage.
Weather reports also said rain was expected in
the area, which could hamper rescue efforts in the mountainous region.
Much
of western China is prone to earthquakes.
A magnitude 6.6
earthquake in neighbouring Sichuan province killed about 200 people
earlier this year, five years after almost 90,000 people were killed in a
huge tremor in the same province.
