What Is A Landslide And What Cause Them?

Now there is snow at a spot and when it collapse is forms an avalanche. But this is a different thing called a landslide. A landslide is piles of rock and dirt sliding down covering up roads and destroying buildings. So what cause these landslide to happen. There's heavy rain, volcanic eruptions, earthquakes, human activity and more but I'm talking about the 3 that I know. When heavy rains hits at the spot where the road were at, all the dirt became heavy and wet from the rain and the weight didn't hold. When an earthquake hit were the buildings are at it triggers a landslide and destroy houses and buildings. And now volcanic eruptions. On May 18th 1980 there was a big earthquake and there was a land slide on the north side of Mount St. Helens and destroyed everything and in December 2018 a landslide on the side of Anak Krakatoa triggered from the eruption and caused a tsunami. When your at a spot where there's lots of rock and dirt, stay away at the spot and get out of there. Enjoy the video.
