El Molino: a very large landslide in Colombia

On 10 November 2022 a large landslide occurred at El Molino in Villa Caro, Norte de Santander in Colombia.  Landslides are increasingly common in Colombia, but this is an unusually large event.  Caracol has an article in Spanish about the landslide, whilst Semana has this before and after image of the site:-

It is very difficult to appreciate the scale of this landslide from photographs, but Noti Cucuta has tweeted this helicopter footage of the aftermath of the event:-

There is also another video that has been tweeted by Diario La Opinión:-

And Segunda División del Ejército Nacional has a further helicopter video, which shows the long runout of the landslide:-

The landslide was triggered by prolonged heavy rainfall.  It has resulted in 28 families being rendered homeless, and five people from a single family are reported to be missing, presumed to have been killed.

This landslide is quite reminiscent of the 16 December 2017 Villa Santa Lucia landslide in Chile.  I will need to use satellite imagery to understand it properly.  The landslide was captured on a Planet Labs image on 11 November 2022, so this will be possible in the coming days.  The crown of the landslide is at 7.949, -73.025.  It has a total runout distance (crown to toe) of about 5 km.

I will provide more details in the coming days.
