Natural Hazards
Across
- 4. a storm of heavy hail.
- 6. a long, high sea wave caused by an earthquake or other disturbance.
- 7. a loud rumbling or crashing noise heard after a lightning flash due to the expansion of rapidly heated air.
- 9. a sudden violent shaking of the ground, typically causing great destruction, as a result of movements within the earth's crust or volcanic action.
- 10. the point on the earth's surface vertically above the focus of an earthquake.
- 12. the perceptible natural movement of the air, especially in the form of a current of air blowing from a particular direction.
- 13. an elastic wave in the earth produced by an earthquake or other means.
- 16. a violent disturbance of the atmosphere with strong winds and usually rain, thunder, lightning, or snow.
- 17. a collapse of a mass of earth or rock from a mountain or cliff.
Down
- 1. a fire in scrub or a forest, especially one that spreads rapidly.
- 2. A numerical scale for expressing the magnitude of an earthquake on the basis of seismograph oscillations.
- 3. a prolonged period of abnormally low rainfall, leading to a shortage of water.
- 4. a prolonged period of hot weather.
- 5. A numerical scale for expressing the magnitude of an earthquake on the basis of seismograph oscillations.
- 8. the condensed moisture of the atmosphere falling visibly in separate drops.
- 11. a sudden local flood, typically due to heavy rain.
- 12. the perceptible natural movement of the air, especially in the form of a current of air blowing from a particular direction.
- 14. a system of winds rotating inwards to an area of low barometric pressure, with an anticlockwise (northern hemisphere) or clockwise (southern hemisphere) circulation; a depression.
- 15. an overflow of a large amount of water beyond its normal limits, especially over what is normally dry land:
- 18. he occurrence of a natural electrical discharge of very short duration and high voltage between a cloud and the ground or within a cloud, accompanied by a bright flash and typically also thunder:
