A building collapse occurs when a structure fails to support its own weight or withstand external forces, leading to a sudden and often catastrophic failure. This can happen due to various reasons, including poor construction practices, lack of maintenance, natural disasters like earthquakes, or design flaws. When a building collapses, it can pose significant risks to human life and property. Emergency responders, such as firefighters and rescue teams, are often called to the scene to search for survivors and provide assistance. Investigations typically follow to determine the cause and prevent future incidents, focusing on safety regulations and building codes.
