5.6-Magnitude Earthquake Strikes China's Gansu Province, Injuring 11 and Damaging Thousands of Homes

Early Morning Tremor Jolts Gansu

A 5.6-magnitude earthquake struck Longxi County in Dingxi City, located in China's northwestern Gansu province, on Saturday, September 27, 2025, at 5:49 a.m. local time. The tremor, which had a shallow depth of 10 kilometers (6 miles), injured 11 people and prompted an urgent response from authorities. The epicenter was approximately 140 kilometers (87 miles) southeast of Lanzhou, the provincial capital.

Casualties and Extensive Damage Reported

Of the 11 individuals injured, state broadcaster CCTV reported that all were taken to area hospitals. The official Xinhua News Agency specified that five of six people brought to one hospital were admitted for further treatment and were in stable condition. No fatalities have been reported.

The earthquake caused substantial structural damage across the affected region. Rescue teams confirmed that 17 houses collapsed entirely, and close to 4,000 residential buildings sustained damage. In response to the damage and potential risks, approximately 7,800 people from Longxi and Zhangxian counties were relocated.

Emergency Response and Infrastructure Impact

Following the earthquake, China's Ministry of Emergency Management activated a level-four national earthquake contingency response, the lowest in its four-tier system. The China Earthquake Administration also launched a level-III emergency service response. Wang Xiangxi, emergency management minister and deputy commander of the earthquake relief headquarters at the State Council, urged 'the rapid verification of the earthquake conditions and damage.'

Rescue efforts were swiftly mobilized, with national comprehensive fire and rescue teams arriving at the epicenter. Local fire and rescue forces, along with specialized rescue units, were also dispatched to assist. The earthquake also impacted transportation infrastructure, leading to the suspension of operations for three trains. A high-speed railway passing near Dingxi, designed for speeds between 250 and 350 km/h, was forced to operate at a reduced speed of 40 to 60 km/h.

Geological Context

Gansu province is situated on the northeastern edge of the Tibetan plateau, making it one of China's most earthquake-prone regions. The area frequently experiences seismic activity due to the ongoing collision between the Indian and Eurasian tectonic plates.
