Mass movements of water are called currents. This is equally true for surface water or deeper water.

The mass movements are: slump, creep, falls, slides, flows and avalanche.

The three main types of mass movements are landslides (movement of rock, soil, and debris down a slope), mudflows (rapid flow of a mixture of water, rock, soil, and debris), and rockfalls (sudden collapse or falling of rocks from a steep slope). These mass movements can be triggered by factors such as heavy rainfall, earthquakes, or human activities.
if the steepness of a slope exceeds the stable angle, mass movements become more likely.
Mass movements of water are called currents. This is equally true for surface water or deeper water.
People living on a day to day basis are a group unlikely to be recruited into mass movements for major changes in society. The goals of such people are to merely survive and any distractions such as mass movements, are a low priority.
Mass movements are most common in regions with steep slopes, loose soil or rock material, heavy precipitation, and seismic activity. Areas prone to mass movements include mountainous regions, coastal cliffs, and areas with a history of landslides or rockfalls. Human activities such as deforestation and construction can also increase the risk of mass movements.
