WHY IS A TSUNAMI A HAZARD?

• WAVE HEIGHTS GROW IN SHALLOW WATER
• Best Case Quickly Rising Tide
• Worst Case Wall of water with rocks
• and debris
• Runups gt 30 m

2 TSUNAMI THREATS

• LOCAL / REGIONAL
• Generated nearby
• Strikes shore quickly (in minutes)
• gt NO TIME for official evacuation
• Education, Awareness
• People-centered response recognize / act
  immediately
• DISTANT / OCEAN-WIDE
• Generated far away, instr detection
• Strikes shore later (2 hours)
• gt TIME for official evacuation
• Widespread Damage
• Tsunami Warning Center, then
  
• People-centered response locally-guided safety
  actions

TSUNAMI WARNING AND MITIGATION SYSTEM

• An EFFECTIVE system means
• All persons in
• vulnerable coastal communities
• are prepared
• to respond appropriately, and
  
• in a timely manner
• upon recognition
• that a potentially destructive tsunami
• may be approaching.

6
TWS SYSTEM COMPONENTS END-TO-END SYSTEM MUST
EXIST!
Develop National and Regional Capacity to

• 1. Assess national tsunami
  risk (Hazard assessment)
• 2. Establish national / regional warning center
  against local and regional tsunamis (Warning
  guidance)
• 3. Promote education/preparedness and
  risk reduction against tsunami hazard
  (Mitigation and Public Awareness)

PEOPLE-CENTREDEXERCISES, DRILLS, EDUCATION

• Government Preparedness
• Worst Case Scenarios
• Emergency Response Exercises
• Pre-Disaster Mitigation (structural,
  non-structural, policy, awareness/education)
• Educate highest government leaders,
  utility companies, hotels and resorts,
  beach lifeguards/safety officers, first
  responders for evacuation and immediate aftermath
• Public Preparedness
• What if Im on the beach?
• What if Im in a boat fishing?
• What to do? Where to go? What about my family?
• The roles of schools, community organizations
  (social, religious, cultural, ethnic, gender, age
  )
• Educate to respond appropriately

Considering Vertical EvacuationEngineering
Structural Response to Tsunami Loading
30
For Prototype Seismic-Design Buildings, consider
performance during Tsunami Loading

• Review current codes for tsunami loading
  provisions
• Evaluate prototype structures for
  seismic/tsunami design
• Review past tsunami damage
• Gosh and Fanella
• For Concrete buildings, effect of wind exposure
  conditions and seismic design categories.

31
Tsunami Force ConsiderationsWhich are important
which are not

• Hydraulic Lateral Forces
• full structure
• individual elements
• Impact Force
• floating debris
• Buoyancy Force
• Scour

32
Indian Ocean Tsunami Visual observations to
validate modeled engineering results

• Wave breaks offshore (e.g., laminar flooding)
• Non-structural elements should beak away to allow
  water flow through ground floor
• 3. Vertical evacuation provides safety

Research to ApplicationEngineering Structural
Response to Tsunami Loading - 2005

• Vertical evacuation in multi-story reinforced
  concrete (and structural steel) buildings may be
  appropriate policy for
• All near-source tsunamis
• Remote-source tsunamis
  in densely populated
  areas where horizontal
  evacuation is not feasible
• Research still needed
  before policy adoption

Checklist for Implementation Community
Awareness, Preparedness, Education

• Pilot community preparedness programmes
• Cooperation - natl / local govt /local - intl
  NGOs.
• Replicate nationally
• Incorporate traditional knowledge
• National Disaster Preparedness Day
• Tsunami Awareness Month to reinforce training
• Media training - routine press conf, interviews,
  and special reports
• Coastal zone mgt policy (inundation zones
  non-siting of lifeline / critical facilities)
• Strengthen built environment - EQ shaking and
  tsunami flooding (building codes, engineering
• Coastal vegetative barriers / hard
  countermeasures
• Tsunami preparedness (all-hazards) in schools

SOCIAL SCIENCE PERPSECTIVES FROM AWARENESS TO
PREPAREDNESS COMMUNITY EMPOWERMENT

• Level of preparation and readiness to act
  sensitive to several moderating variables
• Perceived responsibility - is it govt or is it
  you?
• Response efficiency - are you ready?
• Sense of community - are your neighbors
  important?
• The timing of the next tsunami or the last
  tsunami

• Benefits of Whole-of-Government Approach
• Public Safety and Risk Management
• Benefits of Mainstreaming Risk Management
• Implementing CHARM
  (comprehensive hazard
  assessment and risk
  management)

Strengthening the DMOs

• Relevant National Disaster Reduction Plans and
  Public Awareness programmes in place
• Closer links to national planning
• Clear job descriptions / accountabilities
  Relevant skills
  and qualifications Succession planning
  Technological support
• Community-based empowerment
• Understanding Hazards, Accepting your risk
  tolerance !

Keys to System Effectiveness People drive All
Hazards Response

• Warning System Design
• Feedback Loop
• is it working if not, why?
• Scientist Public interaction
• Response System should be
• Robust, Rapid
• Well-organized
• Appropriate for country
• Community Issues
• Suffer main impact
• Spec issues-women, poverty
• Each community unique
• They are the first responders
• Empowerment, risk tolerance
