Tectonic Hazard Profiles: Hazard Impacts, Vulnerability and Resilience
Measuring Tectonic Hazards:
| Measurement | Hazard | Scale |
|---|---|---|
| Richter scale | Earthquake | 0-9 |
| Moment Magnitude Scale | Earthquake | 0-9 |
| Mercalli Scale | Earthquake | I-XII |
| Volcanic Explosivity Index | Volcano | 0-8 |
| Tsunami intensity scale | Tsunami | I-VI |
Hazard Profiles:
infoNote
Tectonic Hazard Profile: A technique used to try to understand the physical characteristics of different types of hazards.
- Can also be used to analyse and assess the same hazards that take place in contrasting locations.
- Based on: Frequency, Duration, Speed of onset etc. ↳ Compares the physical processes that all hazards share.
Problems with Hazard Profiles:
- Degree of reliability when comparing different event types which are measured using different scales.
- To accurately rank multiple hazards on one scale, certain elements of the hazard become inaccurately displayed or must be omitted from the profile itself.
