Impacts of tectonic hazards on natural & human systems - Coggle Diagram
Impacts of tectonic hazards on natural & human systems
volcanoes hazards / negative impacts
Earthquake
Hazards
Soil liquefaction
Loose soil loses soil structure and transform into thick liquid
Cause infrastructure to sink and shift as ground becomes unstable
Critical medical services become disrupted and delayed
Landslides
Occurs on slopes
Ground shaking creates cracks on slopes
Trigger loose rock to fall downslope
Ground shaking
can cause massive property damage, structures would collapse and trap prevent people to escape
Cause communication / electrical lines to snap
harder for people to call emergency services
Lower visibility for first responders to rescue people
Eg, Haiti has a dense population, with weak materials, harder for first responders to rescue due to higher possibility of collapsing buildings and more people to rescue.
due to dense pop. , lesser oxygen enter when buildings collapse, especially at higher altitude towns / villages
Tsunamis
Caused by undersea earthquakes
Fast moving waves and large debris
destroying infrastructure
railway / roads
prevent people to escape
snap communication / electrical lines
preventing people to call emergency services
lower visibility
*Note: The earthquakes usually doesn't kill people, its the buildings and structures around them
Volcano positive impacts
