Impacts of tectonic hazards
human systems
Ground shaking
destroys property and infrastructure
Weakens buildings, bridges, roads and railways, causing them to collapse, making it difficult to rescue people or supply emergency aid
disrupts services
snaps water + gas pipes --> water shortages + disruptions to gas supply
Electricity + communication cables break, affecting important communication services such as tsunami warnings + television broadcasts
causes injuries and fatalities
People may get trapped under collapsed buildings and infrastructure, resulting in loss of lives and injuries
soil liquidation(occurs when saturated loose soil lose its soil structure and transforms into a thick fluid.) :
destroy property + infrastructure
Buildings + other structures can sink and tip in--> damage makes it difficult to rescue people or supply emergency aid.
disrupts service
Electricity + communication cables and water and gas pipes can sink in and snap disrupting supply f these services
roads and railways above liquidefied soil can sink in and get damaged, making it difficult to rescue people or supply aid.
*causes injuries and fatalities
People can get trapped under collapsed buildings and infrastructure, resulting in injuries and loss of lives
Landslides
destroy properties + infrastructure
Debris can bury villages and farms
Disrupts services
Debris can snap electricity and communication cables, and water and gas pipes, disrupting supply of these services.
Roads and railways can be blocked by debris, making it difficult to recues people or supply emergency aid
cause injury
Debris can bury people or hit them, causing injuries and loss of lives
Debris can block rivers, resulting in floods which can drown people
Tsunami
Destroy properties + infrastructure
Fast moving water+ debris in waves can sweep away buildings + infrastructure
Disrupts services
fast moving waters + large debris can snap electricity + communication cables
fast moving water can sweep away roads ad railways making it difficult to rescue people or supply emergency aid
injury + fatality
sweeping waters can drown people
large amounts of debris carried by wave can hit and kill people
Natural systems
Ground shaking
destroy ecosystems
Ruptures oil and chemical factories, polluting land and water
Fractures and uproot trees-->widespread tree injury + death and damage to wildlife habitats
soil liquidation(occurs when saturated loose soil lose its soil structure and transforms into a thick fluid.)
destroys ecosystems
trees sink and tip over--> damages wildlife
may enter rivers--> smothering plants
sewage pipes might be broken + untreated waste materialsmay pollute rvers, killing aquatic species
Land slides
Destroy ecosystems
Fast moving debris can bury huge areas of forest and wetlands
Rivers can be polluted with debris, killing aquatic life
Rivers can be blocked causing floods that can damage nearby ecosystems and properties
tsunami
Destroy ecosystems
seawater can flood huge areas of coastal wetlands and forests damaging habitats
Large amounts of debris carried in by the waves can pollute these areas, damaging ecosystems and killing wildlife
