WINNING THE GLOBAL WAR AGAINST APATHY AND IGNORANCE Walter Hays, Global Alliance for Disaster Reduction, Vienna, Virginia, USA
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.
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) STATUS OF THE WORLD 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 OUR COMPLEX GLOBAL PROBLEMS AT THE BEGINNING 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 REALITY OF THE 21ST CENTURY
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 THE FRAMEWORK OF DISASTER RESILIENCE PROVIDES WORTHY GOALS
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. WE KNOW WHAT TO DO, SO JUST DOIT!
CAUSES OF DAMAGE INADEQUATE RESISTANCE TO HORIZONTAL GROUND SHAKING SOIL AMPLIFICATION PERMANENT DISPLACEMENT (SURFACE FAULTING & GROUND FAILURE) IRREGULARITIES IN ELEVATION AND PLAN EARTHQUAKES TSUNAMI WAVE RUNUP CASE HISTORIES LACK OF DETAILING AND POOR CONSTRUCTION MATERIALS LACK OF ATTENTION TO NON-STRUCTURAL ELEMENTS
ANY COMMUNITY CAN EVALUATE THE VULNERABILITY OF ITS BUILDINGS • An Incremental Process CLARIFY VULNERABILTIES INDENTIFY OPTIONS IMPLEMENT BEST SOLUTION OPTIMIZE INITATE ACTIONS EVALUATE
SOURCE OF INFORMATION • The following graphic characterizations of building vulnerability to earthquake ground shaking were developed by an insurance company and provided to facilitate education and training.
BUILDING ELEVATIONS • Horizontal and vertical changes in symmetry, mass, and stiffness will increase a building’s vulnerability to ground shaking
AN IMPORTANT NOTE • NOTE: The local site geology and the construction materials are key parameters in controlling a building’s performance; analysis of their effects is NOT considered here.

TUSCALOOSA, AL: EF5 STORM WITH 466 KPH (280 MPH) WINDS APRIL 27, 2011
MOUNT KARANGETANG ERUPTS The 1,784 m (5,853 ft) volcano, which is one of Indonesia’s 129 active volcan-oes, is located on Siau.
VOLCANO HAZARDS (AKA POTENTIAL DISASTER AGENTS) • LAVA FLOWS • LAHARS • EARTHQUAKES (related to movement of lava) • “VOLCANIC WINTER”
NATURAL HAZARDS FOR WHICH EVACUATION IS TYPICAL FLOODS GOAL: MOVE PEOPLE OUT OF HARM’S WAY HURRICANES TYPHOONS HIGH BENEFIT/COST FOR SAVING LIVES, BUT LOW BEMEFIT/COST FOR PROTECTING PROPERTY TSUNAMIS VOLCANIC ERUPTIONS WILDFIRES
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
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 ORNO 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
