Which of the following is a common triggering mechanism that causes slopes to fail suddenly?

Question

Quizplus · Accepted Answer

All of the answers listed can be common triggering mechanisms for slope failures. Earthquakes can cause slope instability by shaking the ground and increasing pore pressure in soil and rock. Over-steepening a slope, either through natural processes or human activities such as construction, can cause the slope to become unstable and fail. Heavy rainfall events can saturate the soil and rock, causing landslides and debris flows. Wildfires can increase the risk of slope failure by removing vegetation that holds the soil in place and creating a hydrophobic layer that repels water, increasing the likelihood of runoff and erosion.
