Tectonic hazards Flashcards
Natural hazard
It’s a threat to people or poverty
Tectonic plates
Destructive margins – move towards each other(oceanic and Continental), oceanic plate is denser so forced into mantel - ocean trench formed and volcanoes
Constructive – move away
Conservative – move sideways
Volcanoes
Found at destructive and constructive plate margins
Earthquakes
Occurred at all three plate margins – caused by tension that builds up
Effects and responses
Primary – buildings collapse, people injured/killed
Secondary – leaking gas, unemployment, can trigger landslides
Immediate – rescue people, put out fires, recovered dead bodies, shelter
Long-term – re-house, repair/rebuild buildings
