Chinese firefighters worked in treacherous terrain on Tuesday to help evacuate more than 11,000 people after a magnitude-6.8 quake struck China's mountainous southwestern province of Sichuan a day earlier, killing at least 66 people.
State media footage, taken at the epicentre in Luding county, showed firefighters stretchering an injured person across a makeshift bridge built with tree trunks as muddy torrents raged below them.
Evacuees who could walk followed a trail of scree alongside the river abutting slopes stripped of soil cover by Monday's quake. Some of them were clutching onto their belongings while others carried injured people on their backs, a video from local media showed.
In another video, firefighters were seen carrying a woman on a stretcher, covered in dust and missing a shoe, out from a dangerously teetering four-storey wooden building.
As rescuers tried to reach stranded people, restore utilities and send emergency relief, state media reported 11,000 people had been evacuated from the area.
Authorities had identified around 500 potential geological hazards, according to the reports, referring to landslides and collapsed mountain roads.
The death toll from the strongest earthquake to hit China's southwestern Sichuan province since 2017 rose to 66 on Tuesday, though dozens of people were suffering heavy injuries.
In all, more than 250 people were injured in the disaster, state media said.
The tremblor struck after midday on Monday, and was felt by residents in the provinces of Shaanxi and Guizhou, hundreds of kilometres away.
On Tuesday, state television reported over 200 people were still stranded in Hailuogou, a popular tourist spot known for its glaciers, verdant forests and soaring peaks. Rescuers were working to reopen roads to reach them.
The powerful earthquake struck Sichuan after midday on Monday, with the epicentre deep in the province's mountainous interior in the west. The quake was felt as far away as the provinces of Shaanxi and Guizhou, hundreds of kilometres away.
In Luding, power and water infrastructure and telecommunications were severely damaged, according to state television.
It also reported that 243 houses had collapsed and 13,010 had been damaged. Four hotels and hundreds of tourist lodgings were also affected.
The quake cut power to several towns, while various highways collapsed and seven small-to-mid-sized hydropower stations suffered damage.
With heavy rains expected over the next three days, experts on Tuesday flagged risks from a number of dammed lakes that have formed after the quake.
Authorities were considering flying drones to inspect the situation upstream of Wandong River, the main tributary of Dadu River.
How often do earthquakes occur there?
Earthquakes are common in Sichuan, especially in its mountains in the west, a tectonically active area along the eastern boundary of the Qinghai-Tibetan plateau.
China's most deadly earthquake in recent decades was in 2008, when a 8.0 magnitude tremblor struck Sichuan's Wenchuan county, killing nearly 70,000 people.
