  • 3. FLOOD A flood is an overflow of water which submerges the area of land. The EU Floods Directive is an overflow of water that submerges land which is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Flooding may occur as an overflow of water from water bodies, such as a river or lake, in which the water overtops or breaks levees, resulting in some of that water escaping its usual boundaries. While the size of a lake or other body of water will vary with seasonal changes in precipitation and melting snow, the flood is not considered significant unless flood water covers areas of land used by man like villages, cities or other inhabited areas; roads, expanses of farmland, etc.

  • 5. LIMNIC ERUPTION A limnic eruption occurs when a gas, usually CO2, suddenly erupts from a deep lake water, posing the threat of suffocating wildlife, livestock and humans. Such an eruption may also cause tsunamis in the lake as the rising gas displaces water. Scientists believe landslides, volcanic activity, or explosions can trigger such an eruption. To date, only two limnic eruptions have been observed and recorded.
  • 6. LIMNIC ERUPTION
  • 7. TSUNAMIS A tsunami can be caused by the undersea earthquakes as the one caused by the 2004 Indian Ocean Earthquake, or by landslides such as the one which occurred at Lituya Bay, Alaska.
  • 8. TSUNAMIS
  • 9. STORM A storm is any disturbed state of an environment or astronomical body's atmosphere especially affecting its surface, and strongly implying severe weather. It may be marked by significant disruptions to normal conditions such as strong wind, hail, thunder and lightning (a thunderstorm), heavy precipitation (snowstorm, rainstorm), heavy freezing rain (ice storm), strong winds (tropical cyclone, windstorm), or wind transporting some substance through the atmosphere as in a dust storm, blizzard, sandstorm, etc.
