Short answer: mostly adapt rather than avoid. People continue to live in places that look “most at risk” because of economic opportunity, history and culture, and lack of better options — and societies use a range of adaptations to reduce the danger. Avoidance (mass relocation) is rare and usually only happens after big disasters or under long-term climate threats.

Key reasons people stay in hazardous places
- Economic benefits: coasts, river deltas and volcanic soils are often the most fertile and best for trade and industry (ports, agriculture, tourism).
- Historical and cultural ties: cities and communities have long roots, infrastructure and social networks that keep people there.
- Limited alternatives and poverty: poorer households often cannot afford to move, and are forced into marginal lands (steep slopes, floodplains, informal coastal settlements).
- Urbanization: as countries develop, people still move to coastal and lowland cities for jobs, even if those locations are risky.

Common adaptations used worldwide
- Engineering and structural measures: seawalls, levees, dams, flood-storage basins, earthquake-resistant building codes, tsunami seawalls. Examples: Netherlands’ Delta Works; Japan’s strict seismic design and tsunami defenses; post‑Katrina levee upgrades in New Orleans.
- Land‑use planning and zoning: restricting building in floodplains, controlled retreat in some areas, hazard mapping to guide development.
- Early warning and preparedness: cyclone and tsunami warnings, evacuation plans, community drills. Bangladesh’s cyclone shelters and warning networks greatly reduced fatalities.
- Insurance and financial tools: catastrophe insurance, disaster relief funds, resilience financing to rebuild smarter.
- Ecosystem-based approaches: restoring mangroves and wetlands to reduce storm surge and erosion (common in Asia and the Pacific).
- Social and behavioral adaptations: seasonal migration, crop changes, and diversified livelihoods.

Regional examples
- Asia: very high exposure (river deltas, seismic zones, cyclones). Countries invest heavily in engineering (Japan), community shelters and warning systems (Bangladesh), and urban flood control (Singapore).
- South America: Andes earthquakes/volcanoes and Amazon basin floods; Chile has strong seismic standards after big quakes. Informal settlements on slopes increase landslide risk.
- North America: hurricane coasts, tornado alley, western wildfires and earthquakes in California; people rebuild, retrofit, buy insurance, or in some cases move inland.
- Europe: flood-prone river basins and Mediterranean wildfire/earthquake zones. The Netherlands and parts of Germany/UK have strong flood-management systems.
- East of Australia (Pacific islands, east coast): tropical cyclones, sea‑level rise and coastal erosion threaten small islands; some communities are already planning or undertaking relocation, while Australia/New Zealand use building codes and coastal management.

Limits and failures
- Adaptation can be expensive and sometimes only postpones risk (e.g., building higher seawalls).
- Governance, inequality and lack of resources often prevent effective adaptation; poor communities remain highly vulnerable.
- In some places (small islands, heavily eroded coasts) avoidance/relocation is becoming necessary as a long‑term strategy.

Bottom line
Most people and governments choose adaptation measures and risk management rather than wholesale avoidance, because the benefits of living in these places often outweigh (or are perceived to outweigh) the risks. Where risk becomes extreme and persistent, managed retreat or migration does occur, but it is expensive and socially disruptive.
