Secondary Volcanic Hazards Flashcards
Define Acid Rain.
Rainfall that is acidic made by atmosphere pollution that causes environmental harm.
Includes sulphur combined with atmospheric moisture.
Define Climate Change.
A change in global or regional climate patterns.
Define Lahars.
Type of mudflow or debris flow composed slurry, rock debris and water flowing down a volcano.
Extremely destructive.as lava combines with ice.
Define Landslides.
Large masses of wet or dry rock and soil that fall, slide or flow very rapidly under force of gravity.
Define Flooding.
Overflow of large amounts of water beyond its normal limits. Or a eruption may melt ice causing this mass flow of water.
Define Tsunami or Tidal Wave.
Series of waves in a water body caused by the displacement of a large volume of water generally in the ocean.
Damage/hazard Acid Rain.
Harmful to wildlife/fish.
Respiratory diseases - asthma.
Damage/hazard Climate Change.
Glacier/ ice melting - polar bears risk.
Loss of sea water.
Intense waves.
Damage/hazard Lahars.
Building and valuable land buried.
Entrapment of people.
Damage/hazard Landslide.
Property damage, injury, death.
Negative economic damage - repair buildings.
Water availability affected.
Damage/hazard flooding.
Social consequences for communities.
Waterborne diseases.
Drowning - death.
Damage/hazard Tsunamis/tidal wave.
Violent flooding.
Loss of life/property.
Sweeping away trees.
Example of Acid Rain from a volcano.
Volcano in Hawaii.
High concentration of sulfur dioxide produce volcanic smog causing persistent health problems.
Example of climate change from a volcano.
Current global average temperature is 0.85’c higher than it was in late 19th century.
Example of lahars from a volcano.
Lahar at el Palmar, Guatemala.
