Earthquake of 6.8 magnitude strikes western China: USGS

BEIJING - Reuters
A strong 6.8-magnitude earthquake struck China's far western region of Xinjiang on Wednesday, the U.S. Geological Survey said.

The tremor was only 12.5 kilometres (eight miles) deep but hit about 270 kilometres east-southeast of Hotan, the USGS said, in an extremely remote part of the region.

China's Earthquake Networks Centre gave the magnitude of the afternoon quake as 7.3. Another quake of magnitude 5.7 struck five minutes later, five kilometres deep, followed by a series of aftershocks of up to 4.2 magnitude, it said. State broadcaster CCTV reported that a journalist felt the shaking as far away as Hotan, but that the city was not seriously affected. An expert told CCTV that the area often experienced earthquakes but was sparsely populated, so the impact was likely to be limited.

No estimate of damage was available so far, the Xinjiang earthquake authority said on a social media account, citing officials from Keriya county near the epicentre. A previous 7.3-magnitude earthquake struck the same county in March 2008, affecting 40,000 people, destroying 200 homes and causing an overall 10 million yuan ($1.7 million) in damage.

China is regularly hit by earthquakes, especially its mountainous western and southwestern regions.

A magnitude 6.6 earthquake in Sichuan province in the southwest killed about 200 people last April, five years after almost 90,000 people died when a huge tremor struck the same province.

Twin 5.6 and 5.9 magnitude quakes killed at least 95 people in the northwest province of Gansu last July.

But according to the USGS website, there was a 65 percent chance the latest quake had not caused any fatalities. "There is a low likelihood of casualties," it said.

Once a link on the Silk Road, Xinjiang covers 1.7 million square kilometres (660,000 square miles) - a sixth of China's territory. It is home to the country's mostly Muslim Uighur minority, and has seen sporadic attacks on police amid complaints by the ethnic group of religious and cultural repression. Beijing has justified tighter security in the area to stem a separatist movement it claims has links with foreign terrorist groups.

Xinjiang is rich in natural resources, containing roughly 30 percent of China's onshore oil and gas deposits and 40 percent of its coal, according to the official website
