Natural DisastersA natural disaster is a severe event resulting from natural processes of the Earth.
Examples: HurricanesFloodsEarthquakesVolcanic eruptionsDrought
Natural Disasters of Latin America
Earthquakes• Caused by the
tectonic plates collidingo Leads to fires,
building collapses and tsunamis
• Occur at fault line, near volcanoes and around the Ring of Fire
Great Chilean Earthquake
• Largest recorded earthquake on the Richter scale – 9.5 on May 22, 1960
• Led to improving the infrastructure in Chile to withstand high magnitude earthquakes
Haitian Earthquake
• 7.0 M earthquake in January 2010 followed by 52 aftershockso Left 1 million
homeless / 530,000 dead or injured
• Haiti’s poor infrastructure caused much of the damage and deaths
Natural Disasters of Latin AmericaVolcanic Eruptions• Generally found where
tectonic plates are pulling away from each othero Earth’s crust is opened
causing lava to come to the surface
• Some of the Caribbean islands were formed through volcanic eruptions
Natural Disasters of Latin AmericaEl Nino & La NinaA warmer/cooler ocean current that flows off the west coast of South America every few years
o Changes weather patterns around the world
• Causes extreme weather like floods, droughts and other weather disturbanceso Agriculture and fishing
are most affected
Natural Disasters of Latin America
Hurricanes• Storms that forms over
warm, tropical ocean waterso Start off the coast of
Africa in the Atlantic Ocean and move west toward the Gulf of Mexico and the Caribbean Sea
• Produces powerful winds, torrential rain, high waves and storm surges
Man-Made Disasters
A man-made disaster is a severe event caused by humans interacting with the Earth.
Examples:DeforestationOil SpillsGlobal WarmingNuclear AccidentHazardous Waste
Man-Made Disasters of Latin America
Deforestation• Cutting down and
clearing away of trees
• The rain forests absorbs carbon dioxide and produces oxygeno Slash-and-burn in
the Amazon produces carbon dioxide and other harmful gases into the atmosphere
Man-Made Disasters of Latin America
Global Warming• The buildup carbon
dioxide in the atmosphere, preventing heat from escaping into space and causing rising temps and shifting weather patterns
Man-Made Disasters of Latin America
Oil-Spills• A release of petroleum
into the environment, due to human erroro Often leads to
catastrophic consequences to the environment and takes years to clean up
Petrotrin Oil spill
• A total eleven oil spills occurred in December 2013 off the Island of Trinidad in the Caribbean.o A massive die-off of
numerous fish & other marine species occurred.
o The fishing industry was also virtually wiped out.
Impact of Disasters
• Human impacto Injury/deatho Loss of homes/property
• Economic impacto Loss of jobs/businesses
• Infrastructure impacto Damaged/destroyed
roads, bridges, power grid, communications
