Tsunami Earthquake storm Feel Do you FEEL the ground shaking severely? Strong earthquakes may cause tsunamis. RUN to high ground if you feel strong shaking. See Do you SEE the water withdraw an unusual distance? As a tsunami approaches land, the ocean may pull back a long way from the shore, exposing the ocean floor, reefs and fish. RUN to high ground if the sea withdraws. Hear Do you HEAR a strange roar? A roaring sound from the ocean is sometimes heard before a tsunami arrives. RUN to high ground if you hear a strange roar. Tsunamis do not necessarily make their final approach to land as a series of giant breaking waves. They may be more like a very rapidly rising tide. This may be accompanied by much underwater turbulence, sucking people under and tossing heavy objects around. Entire beaches have been stripped away by tsunamis. The 2004 Indian Ocean tsunami could rank as the most devastating on record. More than 200,000 people lost their lives, many of them washed out to sea. The Pacific is by far the most active tsunami zone, according to the U.S. National Oceanic and Atmospheric Administration (NOAA). But tsunamis have been generated in other bodies of water, including the Caribbean and Mediterranean Seas, and the Indian and Atlantic Oceans. North Atlantic tsunamis included the tsunami associated with the 1775 Lisbon earthquake that killed as many as 60,000 people in Portugal, Spain, and North Africa. This quake caused a tsunami as high as 23 feet (7 meters) in the Caribbean. How to Know Naturally when Earthquake Will Strike No one can predict when an earthquake will strike, but if you stay in an earthquake prone area, you have to depend on these age old indications of the animals and try to go to a safer places the moment you notice any behavior aberration among the animals. Powerfull storm Powerful storms such as thunderstorms, hurricanes, and tornadoes are generated when warm, light air rises quickly into higher, colder levels in an unstable updraft that can reach over 100 miles per hour. Each type of storm forms under specific conditions; hurricanes occur over moisture-rich oceans and coastlines, for example. They draw their energy from warm ocean waters. Understanding the conditions that give rise to powerful storms is the key to preparing for their devastating effects. Thunder and lightning At any given moment, there are an estimated 2,000 thunderstorms in progress over Earth's surface. These storms can vary from relatively mild rainstorms to very damaging storms that feature hail and high wind. Thunderstorms form when warm air rises from Earth's surface and moves upwards quickly into the colder levels of the atmosphere. If conditions are right, tornadoes can form from this rapid updraft. Normally, however, the result is rain, wind, lightning, and thunder.
