中国西藏那曲市巴青县7.0级地震跟进：受伤人数升至54人 国家地震灾害应急响应提升至三级

那曲——中国西藏自治区那曲市巴青县7.0级地震的伤亡数字再次修订。据新华社10月23日报道，地震已造成16人遇难、54人受伤。这是那曲市抗震救灾指挥部继当日2时25分通报32人受伤、5时20分通报46人受伤之后的又一次上修，遇难人数保持16人不变；此前通报的房屋倒塌及受损339户、牲畜棚圈受损20座等灾情仍在进一步核查中。

与伤亡数字上修同步，中国官方提升了国家层面的响应等级。据新华社报道，地震发生后，国务院抗震救灾指挥部副总指挥、应急管理部部长张成中持续调度指导应急处置工作；根据国家地震应急预案，国务院抗震救灾指挥部办公室、应急管理部将国家地震灾害应急响应由四级提升至三级，并派出由国务院抗震救灾指挥部副总指挥、中国地震局局长王昆带队的工作组赴震区指导协助。应急管理部还指导西藏自治区应急管理厅调派翼龙无人机赶赴灾区，开展灾情侦察任务。

救援力量方面，国家综合性消防救援队伍共调派350人、83台车辆出动救援；截至北京时间10月23日6时30分，已有120人、27台车辆抵达灾区，西藏消防救援总队230人、56台车辆在增援途中，均已行进至那曲境内。此前巴青县已组织1600余人投入抗震救灾一线，救灾物资陆续运抵灾区。据中国地震台网速报目录，截至10月23日7时，震区共记录到余震413次，最大余震4.3级。

这次地震发生于北京时间10月22日22时33分。中国地震台网测定，震中位于巴青县（北纬32.40度、东经93.79度），震源深度10公里；美国地质调查局（USGS）测得震级同为7.0级，最大烈度VIII度。震中5公里范围内平均海拔约4864米，周边人口稀少，震中距西藏自治区首府拉萨约400公里。路透社称，这是2024年1月以来中国境内发生的最强地震；中国地震局此前已启动二级应急响应。

西藏地处印度板块与欧亚板块碰撞带，地震活动频繁。2010年，邻近的青海省玉树藏族自治州发生7.1级地震，造成至少2698人死亡、近300人失踪。

Baqen Earthquake Follow-up: Injured Toll Rises to 54 as China Raises National Earthquake Response to Level III in Nagqu, Tibet

NAGQU — Casualty figures for the magnitude 7.0 earthquake in Baqen County, Nagqu, in China's Tibet Autonomous Region, have been revised again. Xinhua reported on October 23 that the earthquake had killed 16 people and injured 54. It is another upward revision by the Nagqu earthquake relief command, which had reported 32 injured as of 2:25 a.m. and 46 injured as of 5:20 a.m. Beijing time; the death toll remains at 16. Earlier reported damage figures — 339 households with collapsed or damaged houses and 20 damaged livestock sheds — were still being verified.

Alongside the revised toll, China raised its national response level. According to Xinhua, Zhang Chengzhong, deputy commander-in-chief of the State Council's earthquake relief headquarters and Minister of Emergency Management, has been directing the response; under the national earthquake emergency plan, the headquarters office and the Ministry of Emergency Management raised the national earthquake disaster emergency response from Level IV to Level III, and dispatched a work team led by Wang Kun, deputy commander-in-chief of the headquarters and head of the China Earthquake Administration, to the quake zone. The ministry also directed the Tibet regional emergency management department to send a Wing Loong drone to the disaster area for damage reconnaissance.

On rescue forces, China's national fire and rescue service dispatched 350 personnel and 83 vehicles; as of 6:30 a.m. Beijing time on October 23, 120 personnel and 27 vehicles had arrived in the disaster area, while 230 personnel and 56 vehicles of the Tibet fire and rescue corps were en route and had entered Nagqu. Baqen County had earlier mobilised more than 1,600 people for front-line relief work, and relief supplies have been arriving in the area. According to the China Earthquake Networks Center (CENC) catalogue, 413 aftershocks had been recorded in the quake zone as of 7:00 a.m. on October 23, the largest measuring magnitude 4.3.

The earthquake struck at 10:33 p.m. Beijing time on October 22. CENC placed the epicentre in Baqen County, at 32.40 degrees north latitude and 93.79 degrees east longitude, at a depth of 10 kilometres; the U.S. Geological Survey (USGS) also measured magnitude 7.0, with a maximum intensity of VIII. The average elevation within 5 kilometres of the epicentre is about 4,864 metres, in a sparsely populated area about 400 kilometres from Lhasa, the regional capital. Reuters said it was the strongest earthquake to hit China since January 2024; the China Earthquake Administration had earlier activated a Level-II emergency response.

Tibet sits on the collision zone between the Indian and Eurasian plates and is prone to powerful earthquakes. In 2010, a magnitude 7.1 earthquake struck Yushu in neighbouring Qinghai Province, killing at least 2,698 people and leaving nearly 300 missing.
