If you look at a hillside, how can you tell that it's vulnerable to landslides? How can you tell that it's vulnerable to creep?

there are many signs you can see from looking visually.

Explanation:

some areas may be prone to landslides and would have markings from previous ones. some signs can be cracks or bulges in the land. landslides most often occur in either wet and muddy slopes, or in very dry and arid climates. weak rock formations are also prone to falling and creating landslides.
