  • 70% of the marine creatures went extinct
  • reef-building communities almost completely disappeared
  • possible reasons why:
  • global cooling because Gondwana became a glacier
  • major asteroid impact

  • 9.1 magnitude earthquake
  • lasted 10 minutes and the fault broke a total of 1500km, which is the twice the length of Alberta going north to south
  • thrust fault...type of reverse fault
  • tsunami followed affected 12 surrounding nations
  • killing 227,898 and 1.7 million without homes

Geological Natural Disasters

Middle of Paleozoic Era

Devonian Period

End of Precambrian Era

Cenozoic Era

South Pacific Ocean

  • global ice age resulting in mass extinctions
  • largest volcanic eruption
  • lasted 6 million years
  • covered the South Pacific with volcanic rock
  • in some places it was 30 km deep

Egypt and Syria

Africa/Asia Continents

Alaska

North America

The Future

  • deadliest earthquake in history
  • strike-slip fault
  • 1.1 million people killed
  • 9.2 magnitude earthquake
  • resulted from a subduction zone...oceanic plate slide under the continental plate
  • 128 lives lost, but $311 million in damage
  • tsunamis that wiped out entire villages
  • Scientists argue the one day Africa will break in two
  • Super continent

End of Mesozoic Era

Middle of the Paleozoic Era

End of the Paleozoic Era

  • massive freeze
  • resulted in the second largest extinction of all time
  • at least half the marine animal species died
  • extinction of more than half the species, including dinosaurs
  • possible reasons why:
  • major asteroid or comet impact
  • worst extinction in Earth's history
  • 90% of marine animals and 70% of land animals died
  • possible reasons:
  • many volcanoes erupting producing so much as the sun was blocked
  • massive asteroid impact

South America

  • 9.5 magnitude earthquake...largest on record
  • subduction zone
  • killing 1,655 and $550 million in damage
  • tsunami followed with waves as high as 80 feet

1980

Mt. Saint Helens

North America

  • volcanic eruption
  • entire side of the volcano blown away
  • 57 lives lost, but $550 billion in damage

Indonesia

  • deadliest volcanic eruption
  • killing 70,000-90,000 people
  • ash cloud was so large summer was cancelled
