Answer:
Ground Shaking
If an earthquake generates a large enough shaking intensity, structures like buildings, bridges and dams can be severley damaged, and cliffs and sloping ground destabilised. Perched or stacked objects may fall and injure or bury anyone close by. In the largest earthquakes whole districts can be devastated by the multiple consequences of ground shaking.
Groundshaking will vary over an area due to such factors as topography, bedrock type, and the location and orientation of the fault rupture.

Landslides and Rockfalls
Groundshaking due to earthquakes destabilises cliffs and steep slopes, causing landslides and rockfalls as a significant side-effect. Heavy rain and unconsolidated or fractured rock are exacerbating factors.
