Landslide Types and Characteristics

The video explores various types of landslides, including rotational, translational, block slides, rockfalls, topple slides, debris flows, debris avalanches, earth flows, creep landslides, and lateral spread landslides. It discusses their causes, potential dangers, and preventive measures to ensure safety. The video emphasizes the importance of monitoring slopes, using retaining walls, and avoiding construction in high-risk areas. It concludes with a call to action for viewer engagement.

What is another name for a rotational landslide?

• Slump

• Flow

• Slide

• Creep

Which factor is NOT a common trigger for rotational landslides?

• Increased soil weight

• Heavy rainfall

• Snow melt

• Volcanic eruptions

How do translational landslides differ from rotational landslides?

• They move along a curved surface

• They are slower

• They are less destructive

• They move in a straight-line fashion

What is a common trigger for block slides?

• Heavy rainfall

• All of the above

• Seismic activity

• Changes in groundwater levels

What type of landslide involves rocks breaking away from a steep slope and moving downhill?

• Debris flow

• Topple slide

• Earth flow

• Rockfall

Which factor is NOT a trigger for rockfalls?

• Seismic activity

• Erosion

• Heavy traffic

• Freeze-thaw cycles

What is a characteristic of debris avalanches?

• Small distance travel

• Minimal damage

• Slow movement

• High speeds

Which type of landslide involves a mixture of soil, rock, and debris moving rapidly downhill?

• Earth flow

• Creep landslide

• Lateral spread

• Debris flow

What is a characteristic of creep landslides?

• Rapid movement

• Sudden occurrence

• Gradual movement

• High speeds

What type of landslide involves horizontal movement of soil and rock on a gentle slope?

• Rotational landslide

• Translational landslide

• Lateral spread landslide

• Topple slide
