According to the National Oceanic and Atmospheric Administration, tsunamis are a naturally occurring part of Earth's climate and can't be prevented. The best course of action people can take when dealing with tsunamis is to better prepare for them and minimize the damage that tsunamis inevitably cause. Consistent research and effort is being put into developing the means to help global communities mitigate the devastation of tsunamis.
The National Oceanic and Atmospheric Administration and other similar agencies work diligently to establish effective warning systems and educational programs designed to alert people to the impending occurrence of tsunamis far enough in advance that communities are given adequate time to evacuate danger zones. One example is NOAA's Tsunami Warning System, which monitors the Pacific Basin for potential tsunami activity. Between its two centers in Alaska and Hawaii, NOAA is able to serve the areas of Alaska, British Columbia, Washington, Oregon, California, Hawaii and surrounding international locations that may be affected by any seismic activity connected to the Pacific Basin. NOAA states it has been working since 2004 to expand the outreach of its data expedition to include warning services to the Atlantic Oceans and the Caribbean Sea. NOAA also has an educational outreach program called the Hazard Education and Awareness Tool, which informs citizens in threatened areas of how to be prepared in the event of a tsunami.Learn More
As of August 2014, China has not had any significant tsunamis in over 200 years. Historical records suggest a tsunami in 1782 devastated China, killing 40,000 people. In 1765, an estimated 27-foot wave from another tsunami swept up to 10,000 people out to sea. Storm surges are more common than tsunamis in China. A storm surge occurs when a cyclone creates a single wall of water.Full Answer >
A tsunami begins above an undersea earthquake, landslide or volcanic eruption along the ocean floor, explains Lisa Gardiner of the National Earth Science Teachers Association. In the case of an earthquake, when the movement along a fault moves the seafloor upward, water also pushes upward and becomes a tsunami wave.Full Answer >
Tsunamis occur most often in the Pacific Ocean and Indian Ocean, according to the National Oceanic and Atmospheric Administration’s Center for Tsunami Research. Areas along the Pacific Rim are most vulnerable due to the frequent earthquakes that occur. Tsunamis also occur less frequently in the Mediterranean Sea.Full Answer >
While an immediate effect of a tsunami is the destruction of life and property, tsunamis also create a health crisis. Not only do tsunamis wipe out buildings and carry many of the things in their path away, they leave behind a crippled infrastructure that makes it extremely difficult to provide basic services to the people who survived.Full Answer >
