Australian researchers describe a mathematical model in the International Journal of Operational Research that can find the ten optimal sites at which tsunami detection buoys and sea-level monitors should be installed. The model could save time and money in the installation of a detection system as well as providing warning for the maximum number of people should a potentially devastating tsunami occur again in the Indian Ocean.A magnitude 9.3 shook the sea floor off the coast of Aceh, in...
The northeastern U.S. was subjected to heavy flooding and damage from late winter storms, and the Geostationary Operational Environmental Satellite, GOES-12 captured a movie of those storms as they dumped heavy rainfall between March 8 and 16, 2010. "Following the Nor'easter 'parade of blizzards' in February this year, another week-long parade of storms flooded the upper Midwest and Northeastern U.S. in March," said Dennis Chesters of the NASA GOES Project at NASA's Goddard Space...
A unique wave-generating machine that mimics the activity of real-life tsunamis with unprecedented realism has been used successfully in an Oxfordshire laboratory.The simulator has copied the behavior of the first massive wave of the 2004 Boxing Day tsunami.Developed and built with Engineering and Physical Sciences Research Council (EPSRC) funding, the tsunami generator will improve understanding of how tsunamis behave.This will aid development of more effective evacuation guidelines for...
Known as rogue or freak waves, these towering walls of water are simply called monsters of the sea by some people. No matter what they are called, these oversized swells can appear suddenly on the open water and can be large enough to overwhelm even the biggest of ships, according to experts.These rogue waves are believed to be what caused havoc on the cruise ship Louis Majesty this past Wednesday off the Mediterranean coast of Spain. Though not confirmed, three 26-foot waves reportedly...
The first tsunami hit Japan's outlying islands early Sunday after a strong earthquake rocked the South American country of Chile on Saturday morning. Japan's Meteorological Agency said the first wave was recorded in the Ogasawara islands. It was only 4 inches high. Another wave was seen in Hokkaido that was 12 inches high. The Pacific Tsunami Warning Center has already lifted its warning for every country but Russia and Japan. Some countries, including the Philippines, Australia...
Waves impact offshore structures, submarine navigation, moreScientists at the University of Rhode Island are gaining new insight into the mechanisms that generate huge, steep underwater waves that occur between layers of warm and cold water in coastal regions of the world's oceans.David Farmer, a physical oceanographer and dean of the URI Graduate School of Oceanography, together with student Qiang Li, said that large amplitude, nonlinear internal waves can reach heights of 150 meters or more...
MCLEAN, Va., Feb. 24 /PRNewswire-FirstCall/ -- Science Applications International Corporation (SAIC) [NYSE: SAI] today announced it has been awarded a contract for the production and delivery of three SAIC Tsunami Buoy (STB) systems and long-term maintenance services to the Indian National Center for Ocean Information Services (INCOIS), Ministry of Earth Sciences in Hyderabad, India. (Photo: http://www.newscom.com/cgi-bin/prnh/20100224/PH59894) The STB systems will be deployed at...
Aid agency says comparisons to 2004 Indian Ocean tsunami inaccurate, misleading Global shift toward urbanization will set new paradigms for disaster response World Vision announces increased funding commitment for Haiti relief to $50 million in the United States to scale up massive, long-term relief effort PORT-AU-PRINCE, Haiti, Jan. 25 /PRNewswire-USNewswire/ -- The potential death toll and high-visibility of Haiti's deadly earthquake have sparked comparisons to the 2004 Indian Ocean...
Underwater Communication Network May Sense TsunamisTsunamis send electric signals through the ocean that appear to be sensed by the vast network of communication cables on the seabed, according to a new study led by Manoj Nair of the University of Colorado and NOAA.Nair and his colleagues used computer models to estimate the size of an electric field created by the force of the 2004 Indian Ocean tsunami as it traveled over major submarine cables. Salty seawater, a good conductor of...
On the 5th anniversary of the Indian Ocean Tsunami, an international scientific team has cautioned against claims that "˜bioshields' - belts of coastal trees - offer protection from tsunami or storm surges.In fact, planting alien trees along exposed coastlines will do more harm than good, by destroying local ecosystems, displacing people and taking money away from more effective coastal defense projects, according to the scientists. In the wake of the Indian Ocean Tsunami that struck on...

Image Credit: Meteorologist Joshua Kelly When meteorologists are forecasting for ocean-going vessels, there are a few terms that we need to understand. The first term is wavelength. Wavelength is defined as the distance between two crests or between two troughs as seen in the image above. The example above highlights the crest to crest concept of wavelength. The next term that we use is wave height, and to determine this, we first must look at the wave when it passes our station. When...
