WINNING THE GLOBAL WAR AGAINST APATHY AND

IGNORANCE

NOW IS A GOOD TIME TO MAKE OUR WORLD

DISASTER RESILIENT

We can do it through the convergence of realistic thinking and strategic actions that are based on improving community preparedness, protection, response, and recovery.

STATUS OF THE WORLD AT THE BEGINNING OF THE 21ST CENTURY

• 7 billion people, and counting• Living and competing in an interconnected global economy• Producing $60 trillion of products• Facing many complex problems (e,g.,5 E’s and 2 S’s)

OUR COMPLEX GLOBAL PROBLEMS AT THE BEGINNING OF THE 21ST CENTURY

•Conflict and terrorism•Health care• Chronic hunger• Increasing risk of pandemic disease• Large-scale migration of people• Environmental degradation• Increased impacts of natural hazards • Threats related to global climate change

THE REALITY OF THE 21ST CENTURY

Unless we devise and implement a realistic, new strategy, OUR problems may grow worse rapidly, and all of us may share in the blame for an unnecessary reduction in the quality of life on Planet Earth.

THE FRAMEWORK OF DISASTER RESILIENCE PROVIDES WORTHY GOALS

•

•To protect and preserve the environment• To build capacity for disaster resilience• To inform, educate, and train• To build equity in all communities in all regions of the World

WE KNOW WHAT TO DO, SO JUST DO IT!

• Working strategically, we can implement a realistic set of scientific, technical, and political solutions--- within OUR administrative, legal, and economic constraints, --- and become disaster resilient.

CHRONOLOGY OF THE STORM

• Starts in Oklahoma late Thursday (April 14)

• Moves to Arkansas on Friday (April 15)

• Impacts Mississippi and Alabama

TECTONICS OF INDONESIA REGION

• The Australian and Eurasian plates meet in Indonesia, creating a tectonic setting favorable for generating earthquakes, tsunamis, and volcanic eruptions.

Indonesia has 129 active

volcanoes, with two of the most active ones — Mount Kelut and Mount Merapi — on the island of Java, where the Indonesian

capital, Jakarta, is.

SENSITIZED BY THE 2004 TSUNAMI DISASTER, INDONESIANS HEEDED THE

WARNING

This time, the tsunami that inundated towns, immobilized air ports, destroyed buildings, and killed 1,000’s in Japan, WAS NOT DEADLY in Indonesia.

IN 2004, TSUNAMI WAVES REACHED BANDA ACHE IN1/2 HOUR, THEN TRAVERSED THE

INDIAN OCEAN

12 COUNTRIES ADJACENT TO THE INDIAN OCEAN WERE IMPACTED

THE 2004 EXPERIENCE

• THE TSUNAMI WAS GENERATED BY A SHALLOW, M 9.3 EARTHQUAKE LOCATED 260 KM (155 MI) FROM BANDA ACEH, SUMATRA

THE 2004 EXPERIENCE

• THE TSUNAMI WAVES HAD HEIGHTS OF 4 TO 10 M AND RUNUP OF 3.3 KM OR MORE ON THE COAST LINES OF 12 NATIONS

THE 2004 EXPERIENCE

• THE EXISTING TSUNAMI WARNING SYSTEM WAS INEFFECTIVE IN 2004.

• RESULT: LITTLE OR NO EVACUATION.

THE 2004 EXPERIENCE

• AN EXTIMATED 220,000 PEOPLE WERE KILLED (120,000 IN INDONESIA) AND 500,000 WERE INJURED IN 12 COUNTRIES BORDERING THE INDIAN OCEAN
