Comparative Analysis of Earthquakes: Haiti 2010 vs. Japan 2011

Earthquake Data Overview

  • Comparison of Earthquakes

    • The document presents a comparative analysis of two significant earthquake events: Haiti in 2010 and Japan in 2011.

Key Characteristics of Earthquakes

  • Date of Occurrence

    • Haiti: 2010

    • Japan: 2011

  • Death Toll/Injuries

    • Haiti: 230,000 deaths

    • Japan: 28,000 deaths

  • Gross National Income (GNI) per capita

    • Haiti: $760 (indicative of a lower measure of development)

    • Japan: $38,550 (indicative of a higher measure of development)

  • Aftershocks

    • Haiti: None reported

    • Japan: Over 200 aftershocks recorded

  • Level of Preparedness

    • Haiti: Low preparedness level

    • Japan: High preparedness level, including a 1-minute warning signal before the earthquake strikes

  • Level of Urbanization

    • Haiti: Low urbanization rate

    • Japan: High urbanization rate

  • Economic Cost

    • Haiti: $14 billion USD

    • Japan: $309 billion USD

Earthquake Magnitude and Seismic Energy

  • Seismic Energy

    • Understanding the magnitude scale: Each step on the magnitude scale represents a tenfold increase in seismic energy.

    • Seismic energy can be represented in circular diagrams as circles to the scale of the energy produced.

  • Magnitude of Earthquakes

    • Haiti, 2010: Magnitude 7.0

    • Japan, 2011: Magnitude 9.0

  • Descriptive Impact Scale

    • Magnitude 6.0: Destructive but manageable

    • Magnitude 7.0: Disastrous, significant damage and casualties

    • Magnitude 9.0: Catastrophic, widespread devastation
