Hazards and Tectonics

Hazards and Tectonics

1. Hazards

   • Atmospheric (weather)
     • Flooding
     • Tornados
     • Wind
     • Hurricanes
   • Geological hazards (earth)
     • Volcanoes
     • Earthquake
     • Tsunami

2. Tectonic

   • plate margins
     • constructive
       • shield volcanoes
         • Thin Lava
       • Small Earthquakes
         • Mid Atlantic Ridge
     • Conservitive
       • San Andreas Fault
       • Really bad Earthquakes
       • No Volcanoes
         • No magma can get out
     • Destructive
       • oceanic plate subducted
       • Big Earthquakes
       • Composite Volcanoes
         • Very Violent
         • Thick Lava
   • 3P's
     • prediction
       • NOT RELIABLE
       • Japan
         • predicted within 90secs
           • Used tremors
         • Slow down bullet trains
       • Can predict where
         • Not when
         • Istanbul, turkey
     • Protection
       • Create earthquake resistant Buildings
       • Construct Tsunami Walls
       • regular earthquake drills
         • The great California Shake Out
           • raises awareness of problems
     • Planning
       • Maps used to show
         • areas at risk
         • Evacuation Zones
         • Hospitals
   • Earthquakes happen on all plate boundaries
     • volcanoes mostly found here
       • Found in bands
         • Asia
         • Pacific Ocean (Hawaii)
   • Crusts
     • Oceanic
       • Thin
       • Dense
       • Younger
     • Continental
       • Thick
       • Less dense
       • Older
       • Cork
