Precambrian Era
Paleozoic Era
- 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
Mesozoic Era
Cenozoic Era
- 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
West Coast of Northern Sumatra
Asian 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
Japan
Asian Continent
- 9.0 magnitude earthquake
- strike-slip fault...largest on record
- triggered tsunami
- 29,000 lives lost
Chile,
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
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
