Q1A. Explain in detail Hydrological and Geological Hazards elaborating, citing any 2 relevant examples. [5 marks]
Answer
| Hazard group | Explanation | Typical disaster |
|---|---|---|
| Geological | Processes of the solid Earth, such as fault rupture or slope failure. | An earthquake or landslide disaster. |
| Hydrometeorological | Water and weather processes such as intense rain, river flow or cyclone winds. | River flooding or a cyclone disaster. |
| Biological | Pathogens or biological agents affecting populations. | An epidemic. |
| Technological | Failures or hazardous releases involving industrial or engineered systems. | Bhopal industrial gas disaster. |
| Environmental | Degradation or pollution that harms ecosystems and can increase other risks. | Severe toxic contamination affecting water, livelihoods and health. |
Categories can overlap and trigger cascading impacts. For example, an earthquake is geological, but a resulting industrial release is a secondary technological hazard.
Hydrological hazards concern water occurrence, movement and distribution, such as river flooding and dam-break flooding. Geological hazards concern solid-Earth processes, such as fault rupture and slope movement.
