A Tsunami Resilient Community:A Tsunami Resilient Community: • Understands the Nature of the Tsunami Hazard

• Has the Tools to Reduce the Tsunami Risk

• Disseminates information about the Tsunami Risk

• Exchanges Information about the Tsunami Risk

• Institutionalizes Planning for a Tsunami Risk

Who do you need to educate?• Emergency Managers & Planners

• Decision Makers

• Coastal industry & Businesses

• Coastal Residents & Workers

• School children

• Coastal Visitors - Anyone who may visit the coast

• Hazard & Disaster Professionals

Everyone!

Elements of an Education Program:

• Provide accurate information about the hazard

• Describe what are the warning triggers and what people are expected to do

• Motivate people to take appropriate actions

Identify your core message - say it over and over!

Secondary Message:

Natural WarningStrong ground shaking, ocean withdrawal, a sudden change in sea level, or a loud roar from the ocean are all Nature’s warning that a tsunami may be approaching.

Action: immediate self evacuation

Official WarningYou may be notified that a Tsunami Warning has been issued by: TV and radio stations, door-to-door contact by law enforcement, on NOAA weather radios, or in some cases by outdoor siren.

Action:Get off beach; seek more information

You may find out that a tsunami is coming in two ways:You may find out that a tsunami is coming in two ways:

Education Methods:

• Curriculum

• Print material

• Electronic material

• Workshops and community gatherings

• Media

• Signs

• Siren tests

Barriers to Preparedness and Mitigation:

• Unconvinced about risk

• Risk too big to do anything about

• Superstition/belief

• Impact on economy

• Difficult to change behavior - inertia

• Lack of information

• Existing legal & cultural framework

• Conflicting programs/inappropriate programs

• Poverty - higher priority activities

• Lack of funding

Professor Lori Dengler, Humboldt State University - July 30, 2007UW Educational Outreach – Tsunami Science & Preparedness Program (Su 07)

Factors promoting Preparedness and Mitigation:

• Piggyback on successful existing programs

• Take advantage of current events

• Emulate communities with successful programs and publicize achievements

• Engage the public in the process of learning about the tsunami hazard.

• Gain the support of the media

• Redundancy

• Incorporate Social Science Lessons

Professor Lori Dengler, Humboldt State University - July 30, 2007UW Educational Outreach – Tsunami Science & Preparedness Program (Su 07)

Incorporate Social Science:

Identify how people learn in your community

Present educational message in a variety of ways

People generally behave rationally during a disaster

Avoid scare tactics

How to change behavior?

Get people to talk about the hazard

Identify community leaders - get them on your side

Assess the effectiveness of your efforts
