Stones from the Flims Rockslide

Origin
The Flims Rockslide occurred about 10,000 years ago in the Alps. It was the biggest landslide in the area and the biggest in the world where the effects are still visible to this day.

Effects
When it touches the ground, it excites seismic activity, with or without the existence of nearby fault lines. Rocks will shake apart into pieces and large structures are likely to topple. It can also cause landslides in muddy areas, avalanches in snowy areas and rockslides in mountains.
