An 8.8 magnitude earthquake occurred 500 km out of the coast of Sumatra, another area which was also very hard hit in 2004 is India’s Andaman Islands. The second massive quake has been decreased to 8.2 by USGS and it has to be seen as a massive aftershock. Many
After devastating tsunami on March 11 2011, the Japanese government estimated that 5 million tons of debris was swept up by the event. Estimates are that about 70 % sunk to the seafloor and 1.5 million tons left floating. More than a year later, the debris from that
The topography of the seafloor near the coast plays a major role in determining how large tsunami waves become and what places get hit harder than others. Scientists had suspected that the same phenomenon might also take place in the deep ocean, where seamounts
Be it scalar weapon attack, mini nukes in fracture zones or natural occurence the Great Tohoku earthquake or 3/11 Japan earthquake and tsunami generated by it made enormous material damage, took many lives and still threatens to take many more.One year after the
The massive waves were triggered by a devastating 9.0-magnitude earthquake that struck Japan last March and crippled the Fukushima Dai-ichi nuclear power plant, gave the sea floor a huge shove toward Honshu, Japan’s largest island. But until now it has been unclear how
The US East Coast tsunami posibility was main target of new sonar mapping study. Researchers at the U.S. Geological Survey, along with other governmental and academic partners, have been researching the potential for tsunamis generated by landslides in submarine
Two major hazard excercise are scheduled for November 9 2011 and also close approach of asterois 2005 YU55. Testing of Emergency Alert System (EAS) and PACWAVE11, a multi-scenario exercise that will allow PTWS countries to exercise using a destructive local or
Debris from the devastating tsunami that hit Japan on March 11 has turned up exactly where scientists predicted it would after months of floating across the Pacific Ocean. Finding and confirming where the debris ended up gives them a better idea of where it’s headed
