Impact on natural system and human system by ground shaking

• What are the two main systems affected by tectonic hazards?

  Natural and human systems
• What are some hazards associated with earthquakes?

  Ground shaking, soil liquefaction, landslides, and tsunamis
• How does ground shaking impact natural systems?

  It destroys ecosystems
• What are the impacts of ground shaking on human systems?

  It destroys properties and infrastructure, disrupts services, and causes injuries and fatalities
• What are the specific impacts of ground shaking on infrastructure?

  It weakens buildings, bridges, roads, and railways, causing them to collapse
• What happens to water and gas pipes during ground shaking?

  They snap, resulting in water shortages and disruptions to gas supply
• How does ground shaking affect communication services?

  It breaks electricity and communication cables, affecting important communication services such as tsunami warnings and television broadcasts
• What are the hazards associated with earthquakes?

  Ground shaking, soil liquefaction, landslides, and tsunamis
• How does ground shaking affect ecosystems?

  It ruptures oil and chemical factories, polluting land and water, and fractures trees, damaging wildlife habitats
• How does ground shaking affect wildlife habitats?

  It causes widespread tree injury and death and damaging wildlife habitats
• What are the impacts of volcanic eruptions on natural and human systems?

  • Tephra and gases released
  • Lava flows and pyroclastic flows
  • Lahars and landslides
  • Disruption of services
  • Damage to ecosystems and infrastructure
• What are the effects of tectonic hazards on human health?

  • Causes injuries and fatalities
  • Weakens public health systems
  • Disrupts access to medical services
• What are the benefits of living near volcanoes?

  • Fertile soil for farming
  • Access to minerals and building materials
  • Geothermal energy for activities
• What infrastructure was affected by ground shaking during earthquakes?

  Buildings, bridges, roads, and railways
• How does ground shaking disrupt services in human systems?

  It snaps water and gas pipes, and breaks electricity and communication cables
• What are the consequences of snapped water and gas pipes during an earthquake?

  Water shortages and disruptions to gas supply
• How can ground shaking lead to injuries and fatalities?

  People may get trapped under collapsed buildings and infrastructure
• What are the main impacts of ground shaking on natural and human systems?

  • Destroys ecosystems: pollution and tree damage
  • Destroys properties and infrastructure: building collapses
  • Disrupts services: water, gas, electricity, and communication
  • Causes injuries and fatalities: people trapped under debris
• How do the impacts of earthquakes differ between less developed and more developed countries?

  • Less developed countries: often have weaker infrastructure, leading to higher casualties and damage
  • More developed countries: typically have better preparedness and response systems, reducing impacts
