Disaster Management

During a cyclone disaster, it is important to trust official sources of information and protect valuable items by moving them to higher floors to prevent flood damage.

The cyclones in descending order of their occurrence year are Tauktae, Amphan, Fani, and Tith.

The earthquakes are arranged in descending order of magnitude as Bhuj, Gujarat (2001), Darbhanga, Bihar (1988), Uttarkashi, Uttarakhand (1991), and Jabalpur, Madhya Pradesh (1997).

Geological hazards lead to landslides, climate hazards cause floods and droughts, biological hazards result in epidemics, and accidental hazards cause building or bridge collapse.

According to the NDMA Act, 2005, the Prime Minister of India serves as the chairperson of the National Disaster Management Authority.

Hydrological drought occurs when there is a deficiency in surface and groundwater storage, affecting water supply for both human use and ecosystems.

The most catastrophic cyclones on the Saffir-Simpson scale are categorized as Scale-V, which indicates wind speeds of over 157 mph (252 km/h).

Coastal floods are caused by high tidal waves, often as a result of storm surges or tsunamis, affecting coastal areas.

Tsunamis are generally caused by undersea earthquakes, landslides, or volcanic eruptions, not by the collision of continental plates alone.

L Waves, also known as surface waves, cause the maximum damage to structures during an earthquake due to their slow but powerful motion.

Weber's Industrial Location Theory is primarily based on the principle of least-cost location, emphasizing how labor costs impact industrial placement, using the concept of critical isodapane.
