Mountainous Earth Failure: A Preventable Engineering Oversight In mountainous and sloped terrains, soil is never passive. When proper retaining structures are ignored or under-designed, earth failure becomes inevitable. This failure occurred due to the absence of an engineered retaining wall, leading to: *Loss of lateral soil support *Increased pore water pressure *Progressive slope instability *Eventual collapse under self-weight and environmental loads Retaining walls are not aesthetic feature
