Local Tsunamis And Possible Local Tsunamis In Hawaii

Many coastal areas of the United States are at risk for tsunamis. After the catastrophic 2004 tsunami in the Indian Ocean, legislation was passed to expand U.S. tsunami warning capabilities. Since then, the nation has made progress in several related areas on both the federal and state levels. At the federal level, NOAA has improved the ability to detect and forecast tsunamis by expanding the sensor network. Other federal and state activities to increase tsunami safety include: improvements to tsunami hazard and evacuation maps for many coastal communities; vulnerability assessments of some coastal populations in several states; and new efforts to increase public awareness of the hazard and how to respond. Tsunami Warning and Preparedness explores the advances made in tsunami detection and preparedness, and identifies the challenges that still remain. The book describes areas of research and development that would improve tsunami education, preparation, and detection, especially with tsunamis that arrive less than an hour after the triggering event. It asserts that seamless coordination between the two Tsunami Warning Centers and clear communications to local officials and the public could create a timely and effective response to coastal communities facing a pending tsuanami. According to Tsunami Warning and Preparedness, minimizing future losses to the nation from tsunamis requires persistent progress across the broad spectrum of efforts including: risk assessment, public education, government coordination, detection and forecasting, and warning-center operations. The book also suggests designing effective interagency exercises, using professional emergency-management standards to prepare communities, and prioritizing funding based on tsunami risk.

Focuses On The Causes And Effects Of Tsunamis Such As Earthquakes, Landslides, Volcanic Eruptions, And Even Meteorites.

On April 1, 1946, shortly after sunrise, the town of Hilo on the island of Hawai'i was devastated by a series of giant waves. Traveling 2,300 miles from the Aleutian Islands in less than five hours, the waves struck without warning and claimed 159 lives. Fourteen years later, on May 22, 1960, a massive earthquake occurred off of the coast of Chile. The earthquake generated giant waves that sped across the Pacific at 442 miles per hour, reaching Hilo in just fifteen hours. The first wave to hit the town was a modest four feet higher than normal, the second nine feet. Before the third wave could arrive, a tidal phenomenon known as a bore smashed into the Hilo bayfront, with thirty-five foot waves that wrenched buildings off their foundations. That day several city blocks were swept clean of all structures and 61 people died. The first edition of Tsunami!, published in 1988, provided readers with a complete examination of the tsunami phenomenon in Hawai'i. This second edition adds many eyewitness accounts of the tsunamis of 1946 and 1960 and expands its coverage to include major tsunamis in the Mediterranean and off the coasts of Japan, Chile, Indonesia, Fiji, Alaska, California, Newfoundland, and the Caribbean, as well as the 1998 devastation in Papua New Guinea. Dramatic photographs and accounts of experiencing a tsunami firsthand are placed within the framework of the how and why of tsunamis, our scientific understanding of these phenomena, and the current status of the Tsunami Warning System, which is widely used to forecast and measure tsunamis and prepare coastal areas for potentially deadly tsunami strikes.
