Which of these disasters is not categorized under 'Geological Disasters'?

AEarthquakes

BDam Failures

CMine Disasters

DSnow Avalanches

Answer:

D. Snow Avalanches

Read Explanation:

While geological factors like slope stability play a role in where snow avalanches occur, their primary classification is typically under Water and Climate Related Disasters or Hydrometeorological Disasters.

  • Geological Disasters specifically relate to processes originating from the Earth's solid crust, such as earthquakes, volcanic eruptions, landslides (of rock and soil), and tsunamis (often triggered by underwater geological events).

  • Snow Avalanches, on the other hand, are sudden, rapid flows of large masses of snow down a mountain slope. Their formation and release are heavily influenced by:

    • Weather and Climate: Snowfall patterns, temperature changes, wind, and snowpack conditions (e.g., layers, metamorphism) are critical factors.

    • Water Content: The presence and type of water within the snowpack significantly affect its stability.

Therefore, although the terrain (geology) is a prerequisite, the dynamic conditions that lead to an avalanche are overwhelmingly atmospheric and hydrological, distinguishing it from purely geological events.
