A new shallow water buoy, has been tested from the geoscientists of the University of South Florida (USF). After the examination, the geoscientists resulted that the water buoy can detect small movements and Earth’s seafloor changes, which usually lead to natural hazards such as earthquakes, tsunamis or volcanoes.
The UK P&I club received updates on the tsunami that affected Indonesia on December 22. The club recommends that vessels passing through are alert and try to stay clear of the area, as practically as possible. As the alters in the depth of the water aren’t confirmed yet, the area’s naval activity isn’t busy.
Indonesian port of Merak has reopened after the devastating tsunami which was triggered by a combination of underwater landslides caused by the eruption of Mount Krakatoa and an abnormal tidal surge due to a new moon.
Due to increased activities of the Kick em’ Jenny Volcano, the alert level has been raised from Yellow to Orange, advised Grenada’s NaDMA through the technical support provided by the University of the West Indies Seismic Research Center. With this increase in the alert level, ships are asked to observe the exclusion zone of 5 km/3.1miles.
According to marine biologists from the Smithsonian Environmental Research Center, Williams College and other institutions nearly 300 coastal species were detected in Hawaii and the U.S. West Coast, after the tsunami in Japan in 2011, which crossed the ocean by attaching on debris.
Scientists say that a catastrophic tsunami could occur off the coast of Alaska similar to the huge tsunami that killed many people in Japan in 2011 following a 9.0 magnitude quake. They have now found that there are signals for a similar earthquake off the coast of Alaska, resulting in a dangerous tsunami that could devastate parts of the state and reach southerly parts of North America, Hawaii and beyond.
China has set up a tsunami alert centre in the South China Sea in Beijing’s latest effort to bolster its jurisdiction in the disputed waters.
Researchers, funded by NOAA, are partnering with Matson, Maersk Line and the World Ocean Council to equip 10 ships with real-time geodetic GPS systems and satellite communications. The newly built pilot network of GPS-equipped ships enables each vessel to act as an open-ocean tide gauge. Data from these new tsunami sensors are streamed, via satellite, to a land-based data center where they are processed and analyzed for tsunami signals.
