Tectonic processes and hazards

Tectonic processes and hazards

1. Locations at risk

   • Global distribution
     • Earthquakes
       • Often found on plate boundaries
         • Around 70% of all earthquakes are in the "Ring of Fire"
         • Most powerful on convergent and conservative boundaries
         • Distribution of earthquakes reveals a pattern
           • Oceanic fracture zone - along mid-ocean ridges
           • Continental fracture zones - along mountain ranges
           • Intra-plate earthquakes can occur on old fault lines
     • Volcanoes
     • Plate boundary
     • Hot spots and magma plumes
   • Plate movement
