Aeolian deposits.
Mass wasting is considered by geologists as the movement of dirt, rock, sediment, and landscape downhill. Landslides, slump, creep, rock falls, debris falls, rock slides, mudslides, mudflows, lahar, avalanche, and debris flows are all types of mass wasting. Also, any kind of erosion (mechanical/chemical) moving sediment downhill.
Sediment
Erosion deposits sediment.
Its deposits sediment by picking the sediment up which is called plucking.(weathering)
They are both movement of rock and sediment down hillsides
deposition
one of them is sandstone.
When a glacier melts it deposits the sediment it eroded from the land, creating various landforms.
The deposits can be cyclical as with rainfall, floods, tides, seasons.

Earthquakes can trigger (submarine)landslides and debris flows which can act to cause the deposition of sediment, however they are far from the only cause of sediment deposition.
