PHYSICAL
DISTORTMENT OF LAND
PACIFIC DIPPING INTO EURASIAN
TECTONIC STRESS BETWEEN PLates
P AND S WAVES CAUSED DAMAGE (S)
8,8 MAGNITUDE
LASTED FOR 5 MINUTES
LIQUEFACTION
SPEED OF THE TSUNAMI DEPENDS ON –OPEN SEA
FAST AS A JET
HEIGHT DEPENDS ON THE LAYOUT OF THE COASTLINE
Silica are ejected from the volcano=glass that can destroy the turbines of airplanes
ENVIRONMENTAL
HUGE FIRES, OIL SPILLS ETC
NUCLEAR WASTE
SALT WATER INTRUSION
Livelihoods lost
Habitats destroyed
POLITICAL
WARNING SYSTEM WORKED
STRUCTURES IN PLACE
CLEAN UP-BILLION OF DOLLARS
“One of the WORST NUCLEAR DISASTER EVER”
ECONOMICALLY
NUCLEAR TECHNOLOGY END?
INFRASTRUCTURES/INDUSTRIES DESTROYED
ECONOMY RECESSION-MONEY TO REBUILD
SOCIAL/CULTURAL
HOMES LOST
EMOTIONAL DEVASTATION
TOWN WIPED OFF THE MAP
LIVES LOST = ALL PERSONAL BELONGINGS
