Effects of Tectonic Hazards

• Primary Effects - Earthquake:

  • people killed and injured
  • infrastructure damaged
  • gas, water and electricity supplies disrupted or broken
• Secondary Effects - Earthquake:

  • economy slowing due to money being spent on repairs and reduced business activity
  • blocked transport infrastructure restricts emergency access
  • burst water pipes leads to a shortage of fresh water, poor sanitation and illness
  • fires due to broken gas pipes
• Primary Effects - Volcanic Eruption:

  • farmland and property destroyed
  • people and livestock killed and injured
  • restricted air travel due to ash in the atmosphere
  • contaminated water supplies
• Secondary Effects - Volcanic Eruption:

  • glaciers covering volcanoes melt, causing flooding
  • rainfall and meltwater mix with volcanic ash, creating lahars
  • tourism increases
  • ash provides fertile soil
