"The giant earthquakes and tsunamis in Sumatra in 2004 and in Japan in 2011 are examples of the kind of events we'd like to better understand and forecast in the future." Some countries, like Japan, already had good warning systems because they were a land of earthquakes and had been hit by hundreds of tsunamis … Japan is located on the Ring of Fire, an extremely seismically active plate boundary that surrounds the Pacific Ocean. Occasionally, tsunamis can form walls of water (known as tsunami bores) but tsunamis normally have the appearance of a fast-rising and fast-receding flood. “Tsunamis have behaviors, and those behaviors affect the damage they inflict and how prepared you have to be,” Cox says. Tsunamis also form as a result of undersea landslides. Tsunamis have also occurred in Puerto Rico and the Virgin Islands.

Japan is prone to tsunamis and has built numerous tsunami walls along the coast of heavily populated areas. “Near-field tsunamis, like the one in Japan in 2011, only give residents about a 10-minute or less warning of their impact. ... seawalls to protect against tsunamis … Japan is well-rehearsed for quakes and tsunamis As one of the world's most earthquake-prone nations, Japan has had considerable experience of tsunamis. [12] And people forget. Tsunamis are violent and devastating manifestations of our planet, which have the power to wipe out any settlements found on coastal areas. Throughout Japan’s long struggle with seismic activity, tsunamis have devastated the coasts of the country and caused catastrophic disasters. The disaster saw large-scale power outages, three moderate meltdowns at the Fukushima Dai-ichi power plant, more than 18,000 people killed, and it caused damages to the country estimated to be worth about US$34 billion. So when the Tohoku-Pacific Ocean earthquake hit at 2:46 p.m. on March 11, it was at first considered just another temblor. Four years ago, much of Japan’s northeastern coastline was ravaged by the magnitude 9.0 Tōhoku earthquake and tsunami.. The death toll in Japan right now is still rising, with hundreds more missing, and much remains to be seen about the full extent of the disaster. Fact The Japanese government has invested billions in coastal defenses against tsunamis -- for example, building concrete sea walls to blunt the impact of the waves and gates that slam shut to protect harbors. Researchers in Japan are working to find ways to limit the most-catastrophic damage from tsunamis. Before the tsunami, Miyagi Prefecture — which has a mile or more of flat land between the mountains and sea in many places — generally had fewer and shorter seawalls than neighboring regions. Japan’s radical bid to fend off tsunamis with giant, 400km sea wall ... Local leader Takeshi Konno said no construction project will eliminate the need for coastal residents to protect themselves. Japan is arguably the most disaster-aware nation in the world, and has spent several decades developing mitigation strategies for a variety of hazards, including earthquakes and tsunamis. Science correspondent Miles O'Brien reports. It's extremely easy to get injured in an earthquake, so if you feel the ground shaking for more than 20 seconds, drop to the ground and take cover under a desk or table, making sure to hold on tightly. The 8.9-magnitude (which may have been upgraded to a 9.0) earthquake that struck Japan triggered tsunamis across the region. Japan thought it was prepared.

Arikawa says a system to protect … Due to the size and speed, there is no way to stop a tsunamis after it has been set in motion. The walls promise protection from tsunamis that occur once every few dozen to 100-plus years — not the much rarer mega-tsunamis like that of 2011.
