Classifications of Natural Disaster
There are four different types of classifications of natural disaster
- Atmospheric Classification
- Terrestrial Classification
- Aquatic Classification
- Biological Classification
1. Atmospheric Classification
Earth’s atmosphere is the primary location for natural disasters, which are the focus of atmospheric classification. These catastrophes are caused by conditions and atmospheric circumstances.
Examples of Atmospheric Classification
|
Atmospheric Disasters |
Examples |
|---|---|
|
Storms |
Thunderstorms, Hailstorms, Blizzards |
|
Tropical Cyclones |
Hurricanes, Typhoons, Cyclones |
|
Tornadoes |
Violent tornadoes, Twisters |
|
Droughts |
Prolonged dry spells, Water scarcity |
|
Extreme Temperature |
Events Heat Waves, Cold Waves, Frost Events |
2. Terrestrial Classification
Natural catastrophes that affect land surfaces, such as geological and geomorphological hazards, are the main emphasis of the terrestrial classification.
Examples of Terrestrial Classification
|
Terrestrial Disasters |
Examples |
|---|---|
|
Earthquakes |
Seismic Events, Tremors |
|
Volcanic Eruptions |
Lava Flows, Ashfall, Pyroclastic Flows |
|
Landslides |
Rockfalls, Mudslides, Debris Flows |
|
Avalanches |
Snow Avalanches, Ice Avalanches |
|
Soil Erosion |
Wind Erosion, Water Erosion |
3. Aquatic Classification
Natural catastrophes that happen in bodies of water, such as lakes, rivers, seas, oceans, and groundwater, are the focus of the aquatic classification.
Examples of Aquatic Classification
|
Aquatic Disasters |
Examples |
|---|---|
|
Floods |
Flash Floods, River Flooding, Coastal Flooding |
|
Tidal Waves (Tsunamis) |
Seismic Tsunamis, Landslide Tsunamis |
|
Ocean Currents |
Gulf Stream, Kuroshio Current |
|
Storm |
Surge Coastal Storm Surges, Seawater Inundation |
4. Biological Classification
Natural catastrophes that affect living things and ecological systems are categorized as biological classification.
Examples of Biological Classification
|
Biological Disasters |
Examples |
|---|---|
|
Plants and Animals as Colonisers |
Ecological Succession, Pioneer Species |
|
Insects Infestation |
Locust Swarms, Bark Beetle Outbreaks |
|
Fungal, Bacterial, and Viral Diseases |
Bird Flu Outbreaks, Dengue Fever Epidemics |
Classification and Types of Disasters and Natural Hazards| Class 11
Understanding the different classifications and types of natural hazards and disasters is essential for studying geography. These phenomena cover a broad spectrum of occurrences, including atmospheric disturbances like hurricanes and floods as well as geological upheavals like earthquakes and volcanic eruptions. Examining these divisions sheds light on the dynamic interactions that shape our world and helps develop mitigation and preparedness plans for disasters.
