Latest Deep-ocean Assessment and Reporting of Tsunamis Stories
While the waves from a tsunami can be extremely destructive, acoustic waves could help warn of the impending danger.
Commercial ships travel across most of the globe and could provide better warnings for potentially deadly tsunamis, according to a study published May 5 by scientists at the University of Hawaii – Manoa (UHM) and the National Oceanic and Atmospheric Administration's Pacific Tsunami Warning Center.
The deadly tsunami generated from the March 2011 Tohoku-Oki earthquake that devastated northeastern Japan resulted from merging waves, causing the killer tsunami to double in intensity over ocean ridges, and then amplifying its power upon landfall.
The nation's ability to detect and forecast tsunamis has improved since the 2004 Indian Ocean tsunami, but current efforts are still not sufficient to meet challenges posed by tsunamis generated near land that leave little time for warning.
Scientists are hoping a new set of buoys in the Indian Ocean will provide farmers with information that can better predict monsoons in some of the worldâ€™s most underdeveloped regions.
Researchers are hoping to develop a network of ocean-floor and mobile sensors that would help detect tsunamis in the Indian and Pacific oceans.
Scientists predict killer tsunamis could strike the Caribbean, which lacks a warning system even though its seabed is gouged by some of the world's deepest trenches, where the giant waves can be generated by tectonic activity, and its low-lying islands are heavily populated along their coastlines.
A tsunami warning system could be built in the Indian Ocean in just a year and cost as little as $20 million. But experts warn the high-tech network of sensors and buoys would be useless unless countries like Indonesia beef up communications links to the coastal communities that would be hit by giant waves.
