Precipitation patterns play a significant role in landslide formation as heavy or prolonged rainfall can saturate the soil, making it more prone to landslides. When the soil becomes oversaturated, it loses its stability and cohesion, leading to increased landslide risk. Additionally, intense rainfall can increase the water pressure within the soil, further reducing its strength and triggering landslides. Therefore, understanding precipitation patterns is crucial for assessing landslide hazards and implementing effective mitigation measures.
