  • NATURAL HAZARDS THAT PLACE TAIWANS COMMUNITIES AT RISK

    GLOBAL CLIMATE CHANGEENACT AND IMPLEMENT POLICIES HAVING HIGH BENEFIT/COST FOR COMMUNITY RESILIENCEGOAL: DISASTER RESILIENCE

  • TYPHOONSTAIWAN IS AT RISK EVERY YEAR FROM TROPICAL STORMS AND TYPHOONS FORMING IN THE WESTERN PACIFIC OCEAN, ESPECIALLY IF THEY CAUSE DEVASTATING FLOODS AND LANDSLIDES AFTER LANDFALL

  • Physics Of A Typhoon

  • LESSONS LEARNED ABOUT DISASTER RESILIENCEALL TYPHOONS WITHOUT ADEQUATE PROTECTION, HIGH VELOCITY WIND WILL LIFT THE ROOF OFF OF NON-ENGINEERED BUILDINGS.

  • LESSONS LEARNED ABOUT DISASTER RESILIENCEALL TYPHOONS.DISASTER-INTELLIGENT COMMUNITIES USE TIMELY EARLY WARNING BASED ON CRITICAL INFORM-ATION TO EVACUATE PEOPLE AND PREPARE.

  • TYPHOON MORACOT

  • Morakot was the most devastating storm of the deadly 2009 Pacific typhoon season and was also the deadliest typhoon to impact Taiwan in recorded history

  • MORACOTS FLOODING

  • LOSS OF FUNCTION OF STRUCTURES IN FLOODPLAINFLOODSINUNDATION INTERACTION WITH HAZARDOUS MATERIALS STRUCTURAL/CONTENTS DAMAGE FROM WATER WATER BORNE DISEASES (HEALTH PROBLEMS)

    EROSION AND MUDFLOWSCONTAMINATION OF GROUND WATER CAUSES OF RISKCASE HISTORIES

  • MORACOTS IMPACTSMorakot dumped a total of 2.5 meters (100 inches) of rain on the island.

  • TYPHOON MORACOT: FLOODING CHIATUNG CO.

  • TYPHOON MORACOT: SUBMERGED HOUSE

  • TYPHOON MORACOT: COLLAPSE OF HOTEL

  • TYPHOON MORACOT: RAILWAY BRIDGE DAMAGED

  • LESSONS LEARNED FOR DISASTER RESILIENCEALL TYPHOONSCAPACITY FOR INTELLIGENT EMERGENCY RESPONSE IS ESSENTIAL FOR COMMUNITY RESILIENCE.

  • TYPHOON MORACOT: RESCUE WORKERS

  • TYPHOON MORACOT: EVACUATION BY MILITARY

  • TYPHOON MORACOT: EVACUATION OF ELDERLY

  • OTHER NOTABLE TYPHOONS IMPACTING TAIWAN

  • NATURAL DISASTERS: 2003 TYPHOON DUJUAN TIAWAN 1-3 SEPTEMBERTHOUSANDS OF BUILDINGS AND HOMES INUNDATEDAGRICULTURAL CROPS LOST$320 M LOSS$-- 0 INSURED LOSS42 DEATHS

  • NATURAL DISASTERS: 2001 TYPHOON NARI (TIAWAN) $800 MILLION ECONOMIC LOSS PARTIAL INDEMNIFI-CATION BY INSURANCE 93 DEATHS

  • LESSONS LEARNED FOR DISASTER RESILIENCEALL NATURAL HAZARDSCAPACITY FOR RECOVERY AND RECONSTRUCTION IS ESSENTIAL FOR COMMUNITY RESILIENCE.

  • TYPHOON MORACOT: DEBRIS IN FUGANG HARBOR

  • MAIN INSIGHTS FROM SEVERE WINDSTORMSEARLY WARNING AND EVACUATION TO MOVE PEOPLE OUT OF HARMS WAY ARE VITAL FOR SAVING LIVESWIND ENGINEERING PROTECTS BUILDINGS WIND INSURANCE POOLS SPREADS RISK

  • TOWARDS TYPHOON DISASTER RESILIENCE

  • LANDSLIDES IN TAIWANASSOCIATED WITH TYPHOONS AND EARTHQUAKES

  • MORACOTS IMPACTSAt least 40 people dead, many as the result of a village being buried by a landslide (mudslide) during the storm..

  • TYPHOON MORACOT: LANDSLIDE; AUGUST 2009

  • TYPHOON MORACOT: RESCUE FROM MUDSLIDE AREA

  • LANDSLIDE EXACERBATED BY M6.5 EARTHQUAKE AND RAIN APRIL 26, 2010

  • Following several days of rain, a hillside collapsed onto a three-lane highway over a 300-meter stretch, burying three cars and disrupting traffic.

  • LANDSLIDE AFTER EARTHQUAKE

  • SEARCH AND RESCUE
