What are the four phases of the Disaster Management Cycle?

Prevention, Mitigation, Preparedness, Response, and Recovery & Reconstruction

What does 'Emergency Preparedness' specifically relate to?

The Response Phase before, during, and immediately after an event

What is the first step in the Prevention phase of disaster management?

Identifying potential threats

What is the focus of the Mitigation phase in disaster management?

Addressing resource gaps and improving infrastructure for disaster response

How do disaster management teams test their preparedness plans?

Using live drills or table-top exercises

What happens during the Response phase of disaster management?

Emergency response teams execute their established roles to stabilize the community

What does the Recovery & Reconstruction phase involve?

Remediating what was destroyed and helping people rebuild their lives

How does GIS assist in disaster planning?

By visualizing historical spatial data and identifying threat patterns

What is one benefit of using GIS for emergency preparedness?

It helps keep plans and documentation up to date

How does GIS support dynamic threat tracking?

By keeping layers current with real-time data during major threats

What is the role of the ESRI Threat Response Team?

To maintain current data layers for community emergency response teams

What does GIS provide to enhance contextual awareness for emergency response teams?

Combining dynamic threat layers with demographic and critical infrastructure data

What is the importance of rapid updates in emergency response models?

They provide the most current information for effective decision-making

How does GIS assist in post-disaster recovery?

By providing information on infrastructure and community impact

What is 'living documentation' in the context of disaster planning?

Keeping disaster plans and data current using dynamic GIS layers

What can GIS tools inform disaster planning teams about?

Cluster analysis of historical events and areas prone to disasters

What is a key aspect of the preparedness modeling in GIS?

Using spatial analysis capabilities to model disaster response

What is the significance of the 'Response' phase in emergency preparedness?

It focuses on actions taken during and immediately after a disaster event

What role does the Red Cross play in disaster response?

Providing disaster relief and support to affected communities

What is the goal of GIS analysts when providing data during emergencies?

To produce meaningful data pop-ups rather than just raw data dumps
