The 4 June 2023 landslide at Yongsheng Township in Sichuan Province, China
On 4 June 2023 a fatal landslide occurred at Yongsheng Township in Jinkouhe District, part of the area administered by Leshan City in Sichuan Province in China. The landslide struck the dormitory of a phosphorite mine, killing 19 people. Rescue and recovery operations have concluded.
Yongsheng appears to be located at [29.369, 103.065], although this is unconfirmed and I have not tied down the precise location of the landslide itself.
The landslide itself is interesting. It appears to be to be a failure in a gentle gully, probably initiated at the crown of the landslide scar but then entraining a large volume of material downslope. The location of a destroyed structure is visible, alongside a backhoe.
Note that the crown is located on a hairpin bend on the road, with a small cut visible too. It is hard to believe that this landslide is not associated with the road; a working hypothesis might be that a fill slope was created on the downslope side of the hairpin bend, possibly with material from the road cut, to widen the road at this point, allowing vehicles to swing around the corner. This fill material might then have failed, loading the slope and progressively driving a larger failure. That fill is present is potentially supported by the fine-grained, grey material visible in the upper part of the landslide scar.
Yahoo News also has an image of the site, taken from another angle:
The grey area on the right of the image is reported to be the platform of the mine being developed by Jinkaiyuan Mining Company. Heavy rainfall was reported at the time of the landslide, which injured seven people in addition to the 19 fatalities. This is the early part of the rainy season in China, when most landslides occur.
