Natural disasters are events caused by natural forces of the earth, while manmade disasters are caused by human activities. Both types can severely affect electrical power systems, causing damage, interruption of supply, and safety hazards. Natural disasters include earthquakes, floods, cyclones, lightning, storms, landslides, and extreme temperatures. Earthquakes can damage power plants, substations, transmission towers, and underground cables due to ground shaking and structural collapse. Floods can submerge substations, transformers, and distribution panels, leading to short circuits, insulation failure, and long power outages. Cyclones and storms
