Across
- 2. Violent ejection of steam and volcanic material
- 3. Mass movement mechanism triggered by seismic activity
- 4. A volcanic hazard consisting of a mixture of hot high density rock and gas
- 7. Part of the lithosphere which moves in continental drift
- 9. Plate boundary where new crust is created
- 12. Devastation of infrastructure e.g. roads, railways and industry
- 14. Rock fragments and material ejected from a volcano
- 17. Point on the surface directly above the focus of an earthquake
- 19. Precipitation affected by volcanic gases such as sulphur and nitrogen oxides
- 20. Conservative plate boundary
- 22. 300,000 deaths 180,000 homes destroyed and 1.5 million people homeless following a 7.0 magnitude earthquake here in 2010
- 24. Seismic activity that occurs preceding an earthquake as stress builds
- 25. Location of the 9.1 magnitude tsunami that affected 14 countries on Boxing Day 2004
- 26. Exposure of the ocean floor preceding a tsunami wave hitting land
- 28. Weakness in rock formation often trigger of seismic activity

Down
- 1. Earthquake resistant structures should not do this
- 5. Result of tectonic and/or volcanic activity severe shaking of the ground that can cause mass destruction
- 6. Large area prone to volcanic and seismic activity around the Pacific Ocean
- 8. Destructive mud flow on slopes of a volcano
- 9. Discipline of dealing with and avoiding natural and man made catastrophies
- 10. Sudden swell of high water
- 11. Found at a destructive plate boundary where crust sinks into the mantle
- 13. Water saturated sediment acting as a fluid when shaken
- 15. Logarithmic scale that measures magnitude of an earthquake
- 16. Destructive plate boundary
- 18. Seismic wave propagated by submarine tectonic fault
- 21. Size of seismic or tectonic hazard
- 23. Ruptured gas pipes and electricity lines can cause this potential hazard
- 27. Renewable energy source that creates a high risk of radioactive explosions
