The major internal cause of slope failure is gravity.
Your question is not very clear in fact.Firstly,there are many kind of slope failure,such as landslides.Which one do you mean to?Secondly,every places have their own reason of "slope failure".Which places do you mean to? Anyway,I just share knowledge of mine to you.Hope you won't mind if the question isn't the one you want. What is the causing of landslides in Hong Kong?the causings of landslides in Hong Kong are heavy rainfall,rocks and soil materials and human activities.For detail,find in the questions I have answered.I remember I have answer one like this just in today.
Erosion can weaken the base of a slope, making it more susceptible to mass wasting events such as landslides or rockfalls. By stripping away supporting material, erosion can increase the likelihood of slope failure. Additionally, erosion can transport material downslope, contributing to the accumulation of debris at the base of the slope and potentially triggering mass wasting.
A stable slope is one that maintains its shape and integrity over time without experiencing significant movement or failure. It can withstand various external forces, such as gravity, water, and seismic activity, without significant deformation or collapse. Proper engineering and maintenance practices are often used to ensure the stability of slopes in construction and natural settings.
Moisture can soften the soil or rock beneath a slope, reducing its stability and increasing the likelihood of slumping. Excess water can also increase the pore pressure within the material, making it easier for the slope to fail and cause slumping. In general, higher moisture levels can weaken the materials that make up a slope, making it more susceptible to slumping.
A mass movement of rock and soil suddenly slipping down a slope in one large mass is called a landslide. This phenomenon can be triggered by factors such as heavy rain, earthquakes, or human activities that destabilize the slope. Landslides can cause significant damage to property and pose risks to human lives.

Saturation.
1. shear failure 2. rock flow 3. rock fall
Thension crack is generated by the difference in shear movement along the failure surface or slip plane. It formed in the upper slope face before the major failure surface appeared. So, the total shear resistance and thus the safety factor will reduce after this tension crack developement. However, this tension crack will stop developing when it reaches a critical depth. And, a new tension crack will develope behind that previous crack.
Slope failure, or landslides, can be caused by various factors including geological conditions, weather events, and human activities. Heavy rainfall or rapid snowmelt can saturate soil, reducing its stability. Additionally, the composition of the soil and rock, along with factors like seismic activity or excavation, can contribute to the likelihood of slope failure. Poor drainage, vegetation loss, and construction on unstable slopes further increase the risk.
Factors that can affect slope overload phenomena include the slope angle, geology and soil composition, vegetation cover, rainfall intensity, and human activities such as deforestation and land use change. These factors can contribute to increased weight and stress on the slope, leading to potential instability and slope failure.
Slides that grow uphill by increments are called retrogressive; slides that grow downhill by increments are called progressive.

A landslide typically occurs at the boundary between an unstable slope material and a relatively stable material below. The boundary where the failure happens is known as the "failure plane." Changes in slope angle, heavy rainfall, earthquakes, and human activities can trigger landslides along these boundaries.
1. Gravity. 2. Volcanism. 3. Tectonics. 4. Hydraulics.
The addition of water can decrease the stability of a slope by increasing pore water pressure, reducing the effective stress between soil particles, and decreasing the shear strength of the soil. This can lead to slope failure through processes such as landslides or soil erosion.
