What are the short-term and long-term impacts of natural hazards?

Short-Term Impacts:

Short-term impacts manifest in the immediate aftermath of a natural disaster, typically within the first few days or weeks.

These impacts include:

  • Loss of life and injuries to individuals.
  • Significant damage to buildings and infrastructure.
  • Economic disruptions and environmental degradation.

Initial response efforts focus on emergency search and rescue operations and providing essential medical care, food, water, and temporary shelter.

Long-Term Impacts:

Long-term impacts emerge after the initial weeks and can persist for several years.

These impacts involve:

  • Rebuilding and provision of permanent housing.
  • Restoration and enhancement of educational facilities.
  • Development and improvement of emergency response infrastructure.

The focus shifts to long-term recovery and resilience, aiming to rebuild communities and reduce future vulnerabilities.

Summary

  • Earthquake Protection Strategies

    Effective preparation involves forecasting and warning systems, earthquake-resistant building designs, strategic building locations, and emergency procedures.

  • Earthquake Monitoring Techniques

    Prediction methods include measuring ground surface changes, ground tilt, rock stress, radon gas levels, and unusual animal behaviour, particularly in toads.

  • Building and Land-use Planning

    Prediction methods include measuring ground surface changes, ground tilt, rock stress, radon gas levels, and unusual animal behaviour, particularly in toads.
