The moment when a devastating landslide and flash flood swept through Parun, Nuristan Province, Afghanistan, yesterday.
The National Disaster Management Agency reports 23 dead, 80 injured, and nearly 100 missing as search and rescue operations continue.
In this experiment, Dr Rob Thompson from the University of Reading shows how long it takes a cup of water to soak into parched ground.
This is why heavy rainfall after a drought can be really dangerous & might lead to flash flooding.
🛰️ La grande frana di #Niscemi (CL) vista dallo spazio
Nelle immagini satellitari messe a disposizione dai Vigili del Fuoco (8 vs 27 gennaio) si vede chiaramente perfino il fronte di distacco lungo 4.5 km. Si stima che il volume della frana sia di oltre 350 milioni di metri cubi.
This landslide occurred in Alta, Norway.
It developed on a marine clay substrate that had originally formed in the early Holocene epoch when the area was under sea level. There were no casualties.

🇮🇩 This is just one of the landslides that struck Sumatra, Indonesia. You can see how the soil behaves almost like a liquid.
From the looks of it, this slide began farther down the slope. If something like this started higher up, especially above a populated area, there’d be virtually no chance of escape.
