  • Linking Tectonic Hazard Events to Impact, Vulnerability and Resilience
    • Scales Used for Different Types of Tectonic Hazards
      • Richter Scale
        • Earthquake
        • 0-9
        • Measurement of the amplitude of the waves
        • Logarithmic
      • Mercalli Scale
        • Earthquake
        • I-XII
        • Measures the experienced impacts of an earthquake
        • Relative
          • People experience different amounts of shaking in different places
        • Based in responses
      • Moment Magnitude Scale
        • Earthquake
        • 0-9
        • Describe earthquakes in terms of energy release
        • Based on seismic movement
        • Calculated from the amount of slip on the fault, the area affected and an Earth-rigidity factor
        • Logarithmic
      • Volcanic Explosivity
        • Volcanic eruption
        • 0-8
        • Calculated from the volume of products, height of the eruption cloud and qualitative observations
        • Logarithmic
      • All scales are imperfect as they only measure a couple of physical processes
    • Understanding Tectonic Hazard Profiles
      • Compares the physical processes and helps to identify and rank hazards
      • Difficult to determine reliability
    • A Comparison of Hazard Events in Developing, Developed and Emerging Economies
      • Disaster Risk Index
        • Combines physical exposure to hazards with vulnerability
        • Top countries at risk are the most populated
