BEIJING/KATHMANDU -- A magnitude 6.8 earthquake, opens new tab rocked the northern foothills of the Himalayas near one of Tibet's holiest cities on Tuesday, Chinese authorities said, killing at least 53 people and shaking buildings in neighbouring Nepal, Bhutan and India.

The quake hit at 9:05 am (0105 GMT), with its epicenter located in Tingri, a rural Chinese county known as the northern gateway to the Everest region, at a depth of 10 km (6.2 miles), according to the China Earthquake Networks Centre. The U.S. Geological Service put the quake's magnitude at 7.1.

At least 53 people had been killed and 62 injured on the Tibetan side, China's state-run news agency Xinhua reported.

Southwestern parts of China, Nepal and northern India are frequently hit by earthquakes caused by the collision of the Indian and Eurasian tectonic plates.

A magnitude 7.8 tremor struck near Kathmandu in 2015, killing about 9,000 people and injuring thousands in Nepal's worst ever earthquake. Among the dead were at least 18 people killed at the Mount Everest base camp when it was smashed by an avalanche.

Tuesday's epicenter was around 80 km (50 miles) north of Everest, the world's highest mountain and a popular destination for climbers and trekkers.

Winter is not a popular season for climbers and hikers in Nepal, with a German climber the lone mountaineer with a permit to climb Mount Everest. He had already left the base camp after failing to reach the summit, Lilathar Awasthi, a Department of Tourism official, said.

Nepal’s National Disaster Risk Reduction and Management Authority (NDRRMA) said the tremors were felt in seven hill districts bordering Tibet.

"So far we have not received any information of any loss of life and property," NDRRMA spokesman Dizan Bhattarai told Reuters. "We have mobilised police, security forces and local authorities to collect information," he said.

Many villages in the Nepalese border area, which are sparsely populated, are remote and can only be reached by foot.

Aftershocks, damage

The impact of the quake was felt across the Shigatse region of Tibet, home to 800,000 people. The region is administered by Shigatse city, the traditional seat of the Panchen Lama, one of the most important figures in Tibetan Buddhism.

Chinese President Xi Jinping said all-out search and rescue efforts should be carried out to minimise casualties, properly resettle the affected people, and ensure a safe and warm winter.

Villages in Tingri, where the average elevation is around 4,000-5,000 meters (13,000-16,000 feet), reported strong shaking during the quake, which was followed by dozens of aftershocks with magnitudes of up to 4.4.

Crumbled shop fronts could be seen in a video on social media showing the aftermath from the town of Lhatse, with debris spilling out onto the road.

Reuters was able to confirm the location based on nearby buildings, windows, road layout, and signage that match satellite and street view imagery.

There are three townships and 27 villages within 20 km (12 miles) of the epicenter, with a total population of around 6,900, and more than 1,000 houses have been damaged, Xinhua reported.

Local government officials were liaising with nearby towns to gauge the impact of the quake and check for casualties, and China closed the Everest region to tourists after the quake, it added.

The Tingri tremor was caused by a rupture in what is known as the Lhasa block in an area under north-south compression and west-east stress, CCTV reported, citing Chinese experts.

Since 1950, there have been 21 earthquakes of magnitude 6 or above in the Lhasa block, the largest of which was the 6.9-magnitude quake in Mainling in 2017, according to CCTV.

Mainling is located in the lower reaches of Tibet's Yarlung Zangbo river where China is planning to build the world's largest hydropower dam.

Tremors were also felt in Nepal's capital Kathmandu some 400 km (250 miles) away, where residents ran from their houses.

"The bed was shaking and I thought my child was moving the bed… I didn't pay that much attention but the shaking of (a) window made me understand that it's an earthquake," said Kathmandu resident Meera Adhikarii. "I'm still shaking out of fear and am in shock."

The quake also jolted Thimphu, the capital of Bhutan, and the northern Indian state of Bihar which borders Nepal.

So far, no reports of any damage or loss to property have been received, officials in India said.
