**Hazard Reduction Strategy:**
**Assessment**

## Risk Assessment

**What is likelihood of occurrence?**
**What is expected earthquake impact?**
**What is expected tsunami impact along coast?**
**  **
**Numerical modelling**
**	***Need detailed bathymetry, topography*
*	**TIME models (Tsunami Inundation*
*	**                        **Modeling Exchange)*
**Runup & inundation maps**
**Evacuation maps**
**               **

*January 3, 2002 Mw7.1 Vanuatu earthquake and tsunami                            *
*                         **Tsunami record and Tsunami model based on data*

## Model Results:  Scientific Products

## Assessment - Multiple Hazards Map  

**Assessment - Multiple Hazards Map  **
**Seismic Intensity (Modified Mercalli Scale)  **
**Tsunami Inundation potential  **
**Liquefaction susceptibility  **
**Landslide potential  **

## Assessment and Mitigation: Empirical Evacuation Maps 

**1. Post-Tsunami Scientific Survey - Data Collected:**
**    ****Runup, Inundation, Geology, Structural Damage**
**    ****Eyewitness observations: wave arrival, behavior**
**2. Satellite Imagery (before and after)**
**3. Synthesize => Tsunami Event Flooding Map**

## Assessment and Mitigation: Empirical Evacuation Maps 

**4. Assuming worst case scenario, **
**	****Considering coastal topography and elevation,   roads and other easily managed walking paths, strength and height of buildings ...**
**	****Construct Tsunami Evacuation Map**
**	****Identify Tsunami Shelters**
**	****Construct Tsunami Evacuation Routes**

## Evacuation Maps – Safe Routes

**Planning Elements**
**Identify ALL Stakeholders**
**Workshops with Local Residents**
**Single Access Roads**
**Congregation areas**

***“******Local tsunami evacuation maps developed based on modeling, maps and local oral history”***
***  ***

**Notes:**
Workshops are held within the counties and local communities.  Responders, businesses etc., are invited to participate.  Counties who have tribes invite the tribal council to take part and work with the tribes on their evacuation plan (Though they are sovereign, they must work with the local communities – we may not be able to support them in an event where county resources may be available.)
Based on mapping information, communities are broken down into two categories
Single Access Roads – take longer to evacuate 
Congregation areas – area’s that can be evacuated to
Because of political reasons, congregation areas may not be addressed
Neighborhoods are encouraged to come up with evacuation plans (example:  Many have keys to local timber gates for evacuation purposes
Evacuation routes are coordinated with adjacent counties, state agencies (WSP/DOT), and local businesses where evacuation on their land is required
