JAPAN

AFTER 2:46 PM, MARCH 11

Walter Hays, Global Alliance for Disaster Reduction, University of North Carolina, USA


The earthquake is now a m9 0 event l.jpg

THE EARTHQUAKE IS NOW A M9.0 EVENT

The MEGA-earthquake, which struck at 2:46 pm on Friday, March 11th, would have caused a disaster….

THE EARTHQUAKE IS NOW A M9.0 EVENT

…BUT JAPAN was well prepared to cope with it.

A 7-10 M TSUNAM FOLLOWED IN ABOUT 10 MINUTES

Japan was well prepared to cope with a tsunami, but ….

A 7-10 M TSUNAM FOLLOWED IN ABOUT 10 MINUTES

This tsunami was devastating, inun-dating towns, im-mobilizing airports and roads, destroy-ing buildings, and treating everything (e.g., people, cars) in its path as debris.

Tsunami hazards aka potential disaster agents l.jpg

TSUNAMI HAZARDS (AKA POTENTIAL DISASTER AGENTS)

  • HIGH-VELOCITY, LONG-PERIOD WATER WAVES

  • WAVE RUNUP

  • FLOODING

  • WAVE RETREAT

  • SHORELINE EROSION


Advance warning and vertical evacuation are the keys to surviving a tsunami l.jpg

ADVANCE WARNING AND VERTICAL EVACUATION ARE THE KEYS TO SURVIVING A TSUNAMI

ON MARCH 11TH, MANY PEOPLE HAD TOO LITTLE WARNING AND NO PLACE TO GO


Slide10 l.jpg

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 BENEFIT/COST FOR PROTECTING PROPERTY

TSUNAMIS

VOLCANIC ERUPTIONS

WILDFIRES


Slide11 l.jpg

CAUSES OF DAMAGE

HIGH VELOCITY IMPACT OF INCOMING WAVES

INLAND DISTANCE OF WAVE RUNUP

VERTICAL HEIGHT OF WAVE RUNUP

INADEQUATE RESISTANCE OF BUILDINGS

TSUNAMIS

FLOODING

“DISASTER LABORATORIES”

INADEQUATE HORIZONTAL AND VERTICAL EVACUATION

PROXIMITY TO SOURCE OF TSUNAMI


Monitoring technologies and warning systems are a vital part of the story l.jpg

MONITORING TECHNOLOGIES AND WARNING SYSTEMS ARE A VITAL PART OF THE STORY.


Slide13 l.jpg

KNOWING WHERE, WHEN, AND WHY A TSUNAMI OCCURS IS A VITAL PART OF THE ART AND SCIENCE OF INTELLIGENT EVACUATION.


Intelligent evacuation leave the area or evacuate vertically l.jpg

INTELLIGENT EVACUATION:LEAVE THE AREA OR EVACUATE VERTICALLY

  • LEAVE, IF ENOUGH ADVANCE WARNING

  • EVACUATE TO A TALL BUILDING OR A HIGHER ELEVATION TO GET BEYOND REACH OF THE TSUNAMI’S WAVE RUNUP.


Slide15 l.jpg

THE ART AND SCIENCE OF KNOWING WHEN TO EVACUATE BEFORE A TSUNAMI WAVE ARRIVES AND WHERE TO GO CAN BE THE DIFFERENCE BETWEEN LIFE AND DEATH.


Slide16 l.jpg

EVACUATION FOR A TSUNAMI IS COMPLICATED BY:1) THE SHORT TIME BETWEEN THE EARTHQUAKE AND THE TSUNAMI WAVE ARRIVAL, AND 2)DAMAGE AND LOSS OF FUNCTION TO BUILDINGS AND INFRASTRUCTURE CAUSED BY THE EARTHQUAKE AND ITS AFTERSHOCK SEQUENCE.


Slide17 l.jpg

WHEN YOU CHOOSE NOT TO EVACUATE, OR YOU ARE UNABLE TO EVACUATE, THE ODDS FOR SURVIVAL ARE LOWER, BECAUSE ---


Slide18 l.jpg

YOU CAN’T OUTRUN OR DIVERT10-M-HIGH, DEBRIS-LADEN, OCEAN WAVE THAT ARRIVES WITH A HIGH VELOCITY (E.G., 30+ KM/HR) AND MOVES RAPIDLY INLAND FOR 2-3 KM, OR MORE

Search and rescue is often the last best chance for survival but it has limits l.jpg

SEARCH AND RESCUE IS OFTEN THE LAST BEST CHANCE FOR SURVIVAL, BUT IT HAS LIMITS

ON MARCH 14TH, SOME SEARCH AND RESCUE TEAMS FOUND NO ONE TO RESCUE
