What step involves post-emergency activation of disaster response plans guided by GIS layers for navigation, evacuation, and coordination?

• A. Preparedness
• B. Response
• C. Recovery
• D. Mitigation

Answer: (B)

The main idea here is the response phase, which kicks in after an emergency begins and focuses on immediate action to save lives and protect property. During this phase, plans are activated and coordinated in real time. GIS layers become essential tools the moment the event unfolds: they map current hazards, show which roads are open or blocked, indicate evacuation routes, and reveal where shelters, hospitals, and essential services are located. This spatial view lets responders navigate efficiently, route people to safety, allocate limited resources where they’re most needed, and adapt as conditions change. Before an event, planning and risk reduction happen (preparedness and mitigation), and after the immediate crisis, recovery work begins to restore services and rebuild. But the actual post-emergency activation that uses maps and spatial data to guide actions on the ground is the response phase.
