Understanding Natural Hazards and Risk Factors
Ever wondered why some places seem to get hit by disasters more than others? Natural hazards are threats from natural processes that can harm people or damage property.
There are two main types you need to know. Geological hazards come from land and tectonic processes - think earthquakes, volcanoes, and landslides. Meteorological hazards are caused by weather and climate, including tropical storms and heatwaves.
The actual risk depends on several key factors. Population density matters hugely - more people in an area means higher risk when disaster strikes. A country's capacity to cope is crucial too - wealthier nations (HICs) can build flood defences and evacuate people much better than poorer countries.
💡 Remember: The same earthquake will have very different impacts in Japan compared to a less developed country due to different preparation levels.
The magnitude (how powerful) and frequency (how often) of hazards also affect risk. Some hazards like tropical storms can be predicted, giving people time to prepare, whilst earthquakes happen suddenly with little warning.
