Tsunami Warning, Education, and Research Act of 2014 : ウィキペディア英語版 | Tsunami Warning, Education, and Research Act of 2014
The Tsunami Warning, Education, and Research Act of 2014 () is a bill that would authorize the National Oceanic and Atmospheric Administration (NOAA) to spend $27 million a year for three years on their on-going tsunami warning and research programs.〔 The bill was introduced into the United States House of Representatives during the 113th United States Congress. ==Background== (詳細はlarge lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations of underwater nuclear devices), landslides, glacier calvings, meteorite impacts and other disturbances above or below water all have the potential to generate a tsunami. Tsunami waves do not resemble normal sea waves, because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide, and for this reason they are often referred to as ''tidal waves''. Tsunamis generally consist of a series of waves with periods ranging from minutes to hours, arriving in a so-called "wave train". Wave heights of tens of metres can be generated by large events. Although the impact of tsunamis is limited to coastal areas, their destructive power can be enormous and they can affect entire ocean basins; the 2004 Indian Ocean tsunami was among the deadliest natural disasters in human history with at least 290,000 people killed or missing in 14 countries bordering the Indian Ocean.
