<h3>What is a landslide?</h3>
A landslide is defined as the movement of a mass of rock, debris, or earth down a slope.
Water can trigger landslides and mudslides because it alters the pressure within the slope, which leads to slope instability.
Consequently, the heavy water-laden slope materials (soil, rock, etc.) will succumb to the forces of gravity.
