Units 1–2: concepts and hazards
Last-day TEE revision
All five units: a compact final pass
| Term | Meaning | Example |
|---|---|---|
| Risk | Potential loss arising from hazardous events interacting with exposed and vulnerable people/assets. | Possible damage to homes in a floodplain. |
| Vulnerability | Conditions that make people or assets susceptible to harm. | Weak housing or lack of accessible evacuation transport. |
| Hazard | A process or event with the potential to cause harm. | A cyclone or toxic gas release. |
| Preparedness | Knowledge, plans and resources enabling effective action. | A rehearsed evacuation plan and ready shelters. |
| Mitigation | Measures that lessen likely harm. | Retrofitting a vulnerable building. |
| Hazard | Cause → impact → measure |
|---|---|
| Earthquake | Fault rupture → shaking/collapse → safe design, retrofitting and protective action. |
| Flood | Excess flow/runoff → inundation → basin/drainage management, zoning and warnings. |
| Drought | Water deficit interacting with demand → livelihood/water stress → conservation, allocation and support. |
| Landslide / subsidence | Slope failure / ground sinking → structural/access loss → investigation, drainage, stabilisation and safer siting. |
| Tsunami | Large water displacement → coastal inundation → monitoring and evacuation to safe ground. |
| Cyclone | Organised tropical storm → wind/surge/rain → warnings, shelters and resilient construction. |
| Volcano / avalanche | Magma processes / rapid snow movement → distinct flow/ash/snow hazards → monitoring, exclusion and preparedness. |
| Industrial hazards | Hazardous systems/releases → exposure/contamination → safe design, maintenance and coordinated specialist response. |
