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.
