Identify the incorrect statement regarding the generation of Tsunamis.

  1. Tsunamis are exclusively caused by underwater volcanic eruptions.
  2. Sudden displacements of large volumes of seawater are key to tsunami generation.
  3. Large-scale military testing underwater can trigger tsunamis, though rarely.
  4. Atmospheric pressure changes are a primary cause of tsunami formation.

    Answer:

    A. 2, 3

    Read Explanation:

    While earthquakes, underwater landslides, and volcanic activity are primary generators of tsunamis, any event capable of displacing a significant volume of water in a short period can trigger them. The rapid transfer of energy from the Earth's crust into the water column is the fundamental mechanism, distinguishing them from meteorological phenomena.

    Consider the following statements about Structural Preparedness Measures.

    1. Structural preparedness measures are primarily focused on post-disaster recovery efforts.
    2. These measures include actions taken both before and during a disaster to lessen its impact.
    3. The effectiveness of structural measures often depends on their alignment with the specific hazard they intend to address.

      What is crucial for the success and smooth execution of any Disaster Management Exercise (DMEx)?

      1. Thorough and detailed planning is essential for a successful DMEx.
      2. DMEx can be successful even without prior detailed planning.
      3. Only immediate response mechanisms are required for a DMEx to run smoothly.

        Which of the following statements about earthquakes and their immediate consequences is correct?

        1. Earthquakes are primarily caused by immense forces leading to structural deformation deep within the Earth's interior.
        2. Landslides, tidal waves, and tsunamis are common secondary hazards triggered by earthquakes.
        3. The magnitude of an earthquake is typically measured at its impact zone using the Richter scale.
        4. Only earthquakes with a magnitude of 8 or higher on the Richter scale are generally considered to have devastating effects.

          Which of the following statements about the realism and stress testing in mock exercises is accurate?

          1. The simulated disaster should closely mirror reality to ensure plans are tested under corresponding real-life stress levels.
          2. Mock exercises are designed to avoid any resource constraints or time pressure.
          3. This approach helps evaluate operational capability in an environment dissimilar to actual response conditions.
          4. A key focus of mock exercises is to stress-test existing plans, policies, and procedures.
