Question

‘Prevention is better than cure.’ How does this statement apply to earthquakes? Give reasons to support your answer.

Answer 1

“Prevention is better than cure” applies to earthquakes in the sense that it is impossible to prevent an earthquake, but we can take preventive measures to mitigate their impact, reduce loss of life, and minimise damage to property. Here’s how:

1. Earthquake-Resistant Infrastructure:
   • Building Design: One of the most effective preventive measures is constructing buildings and infrastructure that are designed to withstand seismic forces. In earthquake-prone areas, earthquake-resistant structures can prevent buildings from collapsing, thus saving lives.
   • Retrofitting: Older buildings can be retrofitted with modern earthquake-resistant technology to make them more resilient to shaking.
2. Early Warning Systems:
   • Seismic Monitoring: By using advanced technology to monitor tectonic movements, scientists can issue early warning alerts seconds before an earthquake occurs. Although we can’t predict earthquakes, these warnings give people precious time to take cover or evacuate, reducing the number of injuries and fatalities.
3. Preparedness and Awareness:
   • Public Education: Educating the public about earthquake safety measures (such as "Drop, Cover, and Hold On") can help people react quickly and safely during an earthquake.
   • Evacuation Plans: Having well-rehearsed evacuation plans and designated safe areas ensures that people know how to act in case of a tremor, which can save lives.
4. Land Use and Zoning Regulations:
   • Risk Assessment: Avoiding construction in high-risk seismic zones and enforcing land-use regulations helps to limit the potential damage. Urban planning can ensure that important infrastructure like hospitals and schools is built in safer, less vulnerable areas.
5. Seismic Engineering and Technology:
   • Base Isolation: Base isolators can be used to reduce the movement of buildings during an earthquake by absorbing the shock. Modern engineering techniques are continuously improving to prevent buildings from collapsing.
6. International Cooperation and Research:
   • Sharing Knowledge: Countries prone to earthquakes, like Japan, Chile, and Nepal, share valuable data, research, and technologies to help others prepare and respond more effectively to seismic events.

While we cannot prevent earthquakes, the principle of “prevention is better than cure” applies because preparing in advance can greatly reduce the damage, protect lives, and enhance our ability to recover quickly. The focus should be on preparedness, early warning systems, and building resilience to ensure that when earthquakes do occur, their impact is minimised as much as possible.
