Jeori: a large highway landslide in Shimla district, Himachal Pradesh
Yesterday (6 September 2021) a large landslide blocked National Highway 5 at Jeori in Shimla district, Himachal Pradesh in northern India. The landslide, which occurred at about 9 am, did not cause any casualties. This landslide is particularly interesting as it was caught on video from at least four different angles. The first was collected by someone located on the road itself, fortunately a safe distance away:

Meanwhile, another video was captured from a greater distance away, which provides less detail but gives a better appreciation of the process:-

And a third video was captured from the other end of the road:-

I am not sure I’ve seen a landslide captured from four different perspectives before, so this is a cool event.
Photographs of the site in the aftermath of the landslide site, extracted from one of the videos, suggest that the road was on an artificial bench with an unsupported cut slope above:-

Note the small pile of debris on the road before the main collapse occurred. This indicates that there was some precursory deformation, which presumably provided warning of an impending collapse.
The landslide appears to have occurred in dry weather, but we are in the tail end of the monsoon, which may have played a role in progressively weakening the hillslope.
Works are under way to reopen the road. As usual, these operations carry considerable risk.

There is a lot of traffic backed up prior to the main slide, and a lot of people watching and waiting (with cameras).
This suggests that there had been an earlier fall – stopping the traffic – and that previous experience meant people were waiting until things stabilised (or otherwise). The fact that 4 videos were posted suggests plenty of warning / anticipation of the ‘main event’
Massive Slide!! Thank you for sharing.
It is always the same reason – unsecured cuts in steep rock slopes, which show a limited state of safety, lead to devasting slides or rockfall events. There is no understanding of the clients responsible for design, erection and running those roads in high alpine areas.
