Answer

For earthquake management, GIS provides a common location-based picture for agencies. Data quality, access, update time and field verification determine its usefulness.

1. Mitigation. Combine shaking hazard, soil and building vulnerability to prioritise safer construction and retrofitting.
2. Preparedness. Map hospitals, open assembly spaces, lifelines and access routes; rehearse scenarios with blocked roads.
3. Response. Combine shaking estimates and verified damage reports to prioritise search, rescue and medical deployment. Estimates require field confirmation.
4. Recovery. Map damage and recovery needs; plan safer siting and reconstruction and monitor housing, service and livelihood restoration.

Remote sensing can update affected-area mapping, but weather, resolution, signal availability and processing time may limit observations. Protect sensitive household and health information when sharing maps.
