Environmental Degradation: Earthquakes can trigger landslides and avalanches that destroy fragile ecosystems and forests. Liquefaction can contaminate groundwater supplies, and tsunamis may cause severe coastal erosion and saltwater intrusion into agricultural land.
Political Instability: Inadequate government response to a disaster can lead to social unrest, protests, and even the collapse of administrations. Conversely, disasters can prompt positive policy changes, such as the implementation of stricter building codes and improved hazard management strategies.
Hazardous Material Release: Seismic damage to industrial facilities or nuclear plants can lead to catastrophic pollution, as seen in historical instances where radioactive material or chemicals were released into the environment.
Categorization is Key: When asked about impacts, always structure your answer using the Social, Economic, Environmental, and Political (SEEP) framework to ensure comprehensive coverage.
Distinguish the 'Why': Don't just list impacts; explain the causal link. For example, explain how ground shaking (primary) leads to gas pipe rupture, which causes fires (secondary).
Check for Cascading Effects: Recognize that one impact often triggers another. A landslide (secondary) might block a river, leading to flooding (tertiary), which then causes water-borne diseases (social impact).
Common Mistake: Students often confuse 'hazards' with 'impacts'. A tsunami is a hazard; the resulting destruction of a coastal village is the impact.
