  • JAPAN

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

  • 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.

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

  • NOTABLE PAST TYPHOONS IMPACTING JAPAN

  • THE WORST Super Typhoon Vera, September 21-28, 1959 Killed 5,098; Injured 38,021

  • TYPHOON TALAS: AUG. 25 SEPT. 5 2011

  • SUPERTYPHOON VERA

  • With heavy storm surge, rain, and winds of 160 mph, Vera slammed into the southeastern coast of Japan in Wakayama Prefecture and then proceeded northeast across Honsh, causing widespread wind damage and flooding

  • THE WORST IMPACTS WERE CAUSED BY HEAVY STORM SURGE AND FLOODING, ESPECIALLY IN NAGOYA

  • 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

  • 2011Just 6 months after the historic March 11th earthquake-tsunami

  • TRACKS OF 2011S TYPHOONS

  • TYPHOON TALAS: AUG. 25 SEPT. 5 2011

  • TYPHOON TALASTalas, which left 26 dead, was the worst to hit Japan since 2004, when 98 people were killed or reported missing.

  • TYPHOON TALASOne-half million were advised to evacuate to sheltersThousands were stranded as rain washed out bridges, railways and roads and landslides blocked access

  • TYPHOON TALAS: SEARCH AND RESCUE AFTER LANDSLIDE

  • 2012

  • 22 STORM TRACKS AS OF OCTOBER 21, 2012

  • GUCHOL: 1ST TYPHOON OF SEASON: JUNE 19, 2012

  • GUCHOL: A CAT I STORMGuchol caused heightened concerns for safety at the Fukushima Nuclear Power Plant, damaged earlier in the March 2011 earthquake and tsunami.

  • GUCHOL: A RAINMAKERHigh waves, heavy rain (9 cm/hr) and strong winds impacted the south coast of Honshu as far east as Nagoya and the Izu peninsula, southwest of Tokyo. Evacuation advisory issued for 10,000 residents.

  • SANBA: A SUPER TYPHOON, ENTOUTE TO LANDFALL ON KOREAN PINUNSULA

  • JAPAN: IMPACTS OF SANBAHeavy rain and high velocity winds impacted southwestern Japan. The rain caused flooding and landslides. 67,000 homes in Japan lost power.

  • TYPHOON JELAWATS PATH: SEPT. 20 - OCT. 1, 2012

  • TYPHOON JELAWAT:SEPTEMBER 28

  • WIND OVERTURNED A VEHICLE IN NAHA CITY, OKINAWA

  • The wind field that reached 300 kph when Typhoon Jelawat jumped over Okinawa decreased to 120 kph when it reached Tokyo .

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