What is Natural Hazards: Risk, Prediction & Management?

Managing natural hazards involves a four-stage cycle: mitigation, preparedness, response, and recovery. Mitigation aims to reduce the severity of a hazard's impact (e.g., building sea walls), while preparedness involves planning for the event (e.g., evacuation drills). Response is the immediate action taken after a hazard strikes, and recovery is the long-term process of rebuilding. Prediction, using technology like satellites and seismometers, is crucial for providing early warnings and enabling timely responses.

Board notes: A core topic for AQA, Edexcel, and OCR. Exam questions often focus on comparing hard vs. soft engineering, or evaluating the management of a specific named hazard event.

Worked example

Common mistakes

• 1Mixing up prediction and forecasting. Prediction means saying with certainty when and where a hazard will occur, which is rarely possible. Forecasting is about stating the probability of an event happening in a certain area, which is much more common and scientifically grounded.
• 2Thinking management is only about expensive engineering projects. Soft management strategies, like land-use zoning (not building on floodplains) and public education campaigns, are often cheaper and more sustainable in the long run.
• 3Believing that HICs are always better prepared than LICs. While HICs have more financial resources, strong community cohesion and local knowledge in some LICs can lead to highly effective, low-cost preparedness and response strategies.

Frequently asked questions

• What are the 4 stages of hazard management?

  The four stages are mitigation (reducing impact), preparedness (planning before), response (acting during), and recovery (rebuilding after). This is often called the hazard management cycle.

• Can we predict earthquakes?

  It is currently impossible to predict the exact time, location, and magnitude of an earthquake. Scientists can, however, forecast areas of high risk by studying plate tectonics and historical earthquake patterns, allowing for better long-term planning and building design.
