Energy Sources Introduction

• In 2003, gt 80,000 people died in natural hazards
• The deadliest hazards were earthquakes, heat
  waves, floods, tropical storms, landslides
• The hazards were spread around the world, but
  they were not evenly distributed
• The events were the result of natural systems
  operating at the high end of the energy scale for
  short periods of time in a localised area
