LANDSLIDE

here are the cause of lanslide:

gravity
groundwater table changes

Earthquakes cause vibrations and ground shaking, which induce landslides. Other man-made vibrations such as movement of traffic, opertions of heavy machinery, pile driving and other construction-related vibrations may also cause landslides. Particularly, if these man-made vibrations occur on top of the slope, a landslide could be triggered.

landslide also made bad effect to us such as:

damaging the city, killed people, destroys everything, etc..

soooo.we need to act on it so that won't be happen..

there are solutions to prevent this natural disaster which is:

• plant more trees so when rain comes, more trees will absorb more water so the land won't be falling down.
• try to make the hill not too high, you can pull out rocks inside it and move them.
