- 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
- Richter Scale
- 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
- Disaster Risk Index
- Scales Used for Different Types of Tectonic Hazards
