BEIJING -- China has deployed satellites and unmanned aerial vehicles (UAVs) to aid rescue efforts following a 7.0-magnitude earthquake in Southwest China's Xizang autonomous region on Thursday evening.

The China Aerospace Science and Technology Corporation (CASC) said on Friday that immediately after the disaster, it coordinated and deployed satellite resources to conduct emergency communication support and imaging of the quake-hit area.

The CASC said it has activated multiple high-throughput satellite internet emergency service lines for the Ministry of Emergency Management, local emergency management authorities, and major telecom operators. Additional service line terminals are on their way to the quake-hit area.

In response to satellite imaging requests for quake relief, the CASC immediately mobilized Gaofen-4 and other satellites to observe the quake-hit area. As of 7 am (Beijing Time) Friday, it had delivered four pre-disaster images and three post-disaster images, providing strong support for rescue and relief operations and disaster assessment.

According to the Aviation Industry Corporation of China (AVIC), a UAV Wing Loong took off from an airport in Xigaze of Xizang autonomous region in the early hours of Friday and flew to the quake-hit area to carry out disaster observation and communication support missions.

The AVIC said other Wing Loong teams are ready for deployment.
Chinese People's Liberation Army Air Force also sent a UAV around midnight to the quake-hit area for disaster survey.

Sixteen people were killed and 76 others injured after the earthquake struck Baqen county of Nagqu city in Xizang autonomous region at 10:33 pm Thursday, local authorities said on Friday.

BEIJING -- The 7.0-magnitude earthquake that struck Baqen county of the city of Nagqu in Southwest China's Xizang autonomous region on Thursday was an extensional rupture, according to experts with the China Earthquake Networks Center (CENC).

The quake occurred at around 10:33 pm, causing heavy casualties. Focal mechanism solutions show the event was basically consistent with regional tectonic characteristics.

"An extensional fracture, in simple terms, occurs when the crust is stretched horizontally and, under tension and gravity, faultage slides downward along existing faultage, forming fractures and rupture surfaces," said Han Yanyan, a senior engineer with the earthquake prediction department of the CENC.

The CENC explained that the collision between the Indian and Eurasian plates had caused the uplift of the Qinghai-Tibet Plateau, crustal shortening and thickening, and widespread plateau deformation. These processes are the main dynamic mechanism controlling tectonic deformation in the western part of the Chinese mainland.

The interior of the plateau is subjected to both north-south compression and east-west extension, and two typical fault systems, trending roughly north-south and east-west, have developed there.

"The epicenter is located within the Changtang block of the Qinghai-Tibet Plateau, about 2 km from the nearest fault, the Baqen-Riwoqe fault," Han said.

Under such intense crustal deformation, the Changtang block and its surrounding fault zones are particularly active. Since 1900, the block has experienced six earthquakes of magnitude 7 or above, including this one. The largest was a 7.5-magnitude earthquake in Shuanghu on Nov 8, 1997.

"Therefore, this earthquake was an energy release of the Changtang block," Han said.

Authorities in Nagchu city, Xizang autonomous region, warned at a Friday news conference that aftershocks and secondary disasters remain major risks following a magnitude-7.0 earthquake in Drachen county on Thursday night.

The quake had killed 16 people and injured 76, said Dondrub, mayor of Nagchu.

The affected area averages nearly 4,800 meters in elevation, according to Meng Linghe, Drachen's Party secretary. Landslides, slope collapses, and falling rocks are the main secondary geological hazards. Low nighttime temperatures, scattered snow showers, and black ice on shaded high-altitude roads pose risks to rescue vehicles.

Dondrub said inspections have covered 12 roads spanning more than 1,700 kilometers, 201 bridges, and 324 culverts. Officials identified 11 hazards and cleared rockfalls at seven road locations.

Earthquake, meteorological, and emergency management departments are consulting and issuing aftershock and weather warnings, while police and transport authorities keep emergency routes open.

Round-the-clock monitoring and emergency repairs cover mountain slopes, reservoirs, power stations, river channels, unsafe buildings, and telecommunications base stations. Authorities are inspecting mountain slopes and roads alongside rescue teams, Meng said. Dangerous areas will be cordoned off, and search operations will be kept away from steep slopes.

Authorities will inspect geological hazard sites and vulnerable infrastructure hourly and continue issuing updated risk alerts, Dondrub said.

China's transport authorities have stepped up road inspections and emergency support to ensure rescue vehicles can reach areas affected by a magnitude-7.0 earthquake in Southwest China's Xizang autonomous region.

Roads in the quake-hit area are under traffic controls, with access maintained for rescue vehicles while other vehicles are temporarily barred, according to the Ministry of Transport.

The earthquake struck Drachen county in Nagchu at 10:33 pm on Thursday. By 10 am Friday, 16 people had been killed and 76 injured, according to local authorities.

The ministry activated a Level III emergency response for road transport at 9 am Friday and dispatched a team to coordinate rescue support and efforts to keep roads open. It is also coordinating with the Ministry of Finance to arrange emergency funding for road clearance and repairs.

Level III is the second-lowest level in the ministry's four-tier response system, with Level I being the highest. Xizang's transport department activated its own Level II response after the earthquake.

Local highway authorities deployed 178 personnel and 39 pieces of machinery to inspect affected sections of five national highways and seven provincial roads. They have checked 2,377 kilometers of roads, 295 bridges and 635 culverts.

The inspections found varying degrees of damage along sections of national highway G345 and provincial highway S301. More detailed inspections of roads, bridges and other transport infrastructure are continuing.

Emergency equipment is being sent to the disaster-hit area from reserve centers in Lhasa and Qamdo to help crews clear debris and repair roads.

Crews from nearby construction projects run by centrally administered State-owned enterprises, along with other road maintenance teams, are on standby to provide additional support.

Electricity and communications have been restored in some villages in the hardest-hit areas of Drachen county, Xizang autonomous region, following a magnitude-7.0 earthquake on Thursday, according to the Xizang Communications Administration.

State Grid Xizang Electric Power activated its emergency response and dispatched teams overnight to Gangche and Maru townships to inspect and secure power facilities.

Electricity has been restored across the area surrounding the Maru township government offices. Phone and internet services have also returned to normal in two villages in the township. Being close to the earthquake's epicenter, they were among the most affected areas.

According to the administration, the earthquake knocked 628 mobile base stations offline, accounting for 8.5 percent of the city's total. These stations have been restored as of 10:30 am Friday, bringing communications in the affected area back to pre-earthquake levels within 12 hours.

The administration said 131 emergency repair personnel and 50 vehicles had been deployed to restore communications, along with 38 generators and other emergency equipment. Telecommunications networks in the disaster area are now operating normally, supporting the coordination of rescue operations.

Earthquake authorities in Yunnan and Sichuan provinces have sent a dozen personnel to the affected area to assess the quake's intensity, verify damage, and conduct other emergency field operations.

Sixteen people have been killed and 76 injured as of 1 pm Friday following Thursday's magnitude-7.0 earthquake in Drachen county, Xizang autonomous region, officials said at a news conference Friday.

Dondrub, mayor of Nagchu city, which administers the county, said rescuers had completed three rounds of searches, checking key areas and visiting residents in remote, scattered settlements.

Authorities have set up 18 temporary shelters and relocated 12,489 people, he said. Due to the quake, 339 households have collapsed or been damaged, along with 20 livestock sheds.

The immediate priorities are treating the injured and ensuring displaced residents have access to basic necessities, he said. Authorities will provide insulated tents and hot meals, with particular attention to older people, children, pregnant women, new mothers, and people with disabilities.

Rescuers went door to door in villages near the epicenter of a magnitude-7.0 earthquake that struck Drachen county, Xizang autonomous region, looking for anyone in need of help.

In Gangche township, one of the areas closest to the epicenter, rescue workers began searching for people trapped in their homes in the early hours of Friday morning.

Surveillance footage shared by local media showed buildings shaking violently, with goods tumbling from shelves as residents rushed outside to escape the quake on Thursday night. In Maru township, one of the hardest-hit areas, the earthquake cracked the ground and caused sections of road to sink, China Central Television reported.

"Suddenly, there was a tremendous rumbling. For a moment, it felt as if hundreds of yaks were running at once," said Dzondru Tseltrim, a resident of Garuthang village in the county.

His family had already gone to bed when the shaking began. Woken by the tremors, he heard cabinets and wooden pillars creaking inside the house. He rushed to wake his father, in his 80s, and helped him outside. Other family members soon followed.

Fearing aftershocks, the family decided not to sleep indoors that night. They arranged for his father to rest in a car while the others prepared to spend the night in the courtyard.
