Heishui: a rockslide at a tunnel portal in Sichuan Province, China
Loyal reader Mark Shore has kindly highlighted an interesting rockslide that was caught on video in Heishui County, in Sichuan Province in China. The landslide apparently occurred on 30 September 2021. The two tweets below capture the event:-
Whilst the video below captures the aftermath and, at the end, some further landslide activity:
Clearly this type of event is exceptionally dangerous – it is perhaps surprising that there is no apparent landslide mitigation on the slope or around the portal given the obvious potential for rockslides at this site. According to a report in NTDTV.com, in Mandarin, the landslide occurred at 9:20 am at the entrance of the Xi’er Tunnel of National Highway 347 in Heishui County, Aba Prefecture, Sichuan. There were no casualties, but a transformer and a car were damaged.
Some reports suggest that an accident was avoided because a security officer at the site raised the alarm.
Mark has identified the likely location for the landslide, which is at 32.080° N, 103.181° E:-
Clearly this is a location with a high incidence of landslides, but it seems like that the slope above the tunnel portal shown in the Google Earth image has been quarried.
