What each of these has in common is that they were local, rapid onset events, where tsunami waves arrived on the shore quickly, and in some places before warnings were issued or before people could evacuate to safety. The horrific scenes of destruction that we have witnessed through the media over the last three days should act as another reminder for countries with communities living close to potentially tsunamigenic zones to step up their efforts to develop awareness, preparedness and mitigation measures.

Communities must learn to recognize the natural warning signs and act immediately to save their lives. Focused research is also required to continue updating our knowledge about subduction zones capable of generating great earthquakes and tsunamis. The IOC stands ready to support these activities in collaboration with partners and is more than ever committed to the goal of developing effective end-to-end tsunami warning systems at the regional, national and local level.

The 11 March magnitude 9. As of 30 May , the Japan National Police Agency reports 15, persons killed and 8, persons missing from the earthquake and tsunami.

On 7 April , a M7. Live video of the advancing tsunami waves and their impact on structures at the coast was aired by Japan NHK television and seen at the same time globally. Waves overtopped tsunami walls and destroyed many structures, especially wooden homes. Nonetheless, some tall reinforced concrete buildings and evacuation platforms did survive and allowed citizens to shelter in place by vertically evacuating.

Tsunami waves also caused huge infrastructure damage to the Fukushima Nuclear Power Plant, resulting in the meltdown of core reactors and local emission of dangerous radiation.

Like the previous tsunamis, drowning was the main cause of death, with casualties greatest in the elderly. The 11 March Japanese tsunami was the first to cause deaths since the Sea of Japan magnitude 7.

In comparison, the most fatal and damaging tsunami that has ever occurred in the world was the magnitude 9. The most fatal Japanese tsunamis are listed below:.

Six minutes later warnings or watches were issued for islands from the South Pacific to Hawaii, as well as Japan and Russia. In the subsequent 24 hours, the Tsunami waves were tracked across the ocean, and warnings were issued for North and South America.

The Japanese Meteorological Agency monitors sea level gauges continuously in real time and reported these observed tsunami measurments. The IOC is primarily concerned with international coordination among nations, while the operational duties of the centers reside with national agencies. Tsunami early warning systems are based on observation networks of seismometers and sea level measuring stations, which send real time data to national and regional tsunami warning centers TWCs.

Based on these observations, TWCs are able to evaluate the potential for a given earthquake to generate a tsunami, and confirm or cancel a tsunami warning advisory. When a potentially destructive tsunami is detected, national authorities decide if a tsunami warning and an evacuation order must be issued to their public. Sophisticated ocean wave models are now used to predict the cross ocean pathways of tsunami propogation.

These results can be used with minutes of tsunami detection to guide warnings and advisories across the oceans. Japan's meteorological agency lifted a tsunami advisory around an hour after a strong 7. An earthquake of preliminary magnitude of 4. The word tsunami had entered the lexicon of journalists in newsrooms around the world after the December Indian Ocean tragedy, and on 11 March , when news broke of tsunami waves striking the coast of east Japan, there was a sense that this had the potential of becoming a major crisis.

Japan will tomorrow mark 10 years since the devastating earthquake and tsunami, followed by the Fukushima nuclear disaster, the worst natural disaster in the country's history. Many survivors say the unconnected phone line in the town of Otsuchi helps them keep in touch with their loved ones and gives them some solace as they grapple with their grief. A strong 7. Clean-up efforts at Japan's Fukushima nuclear plant, destroyed by a massive earthquake and tsunami in , have significantly reduced radiation levels but untreated forested areas remain a problem, scientists said Thursday.

An earthquake with a preliminary magnitude of 6. More News ». Japan lifts tsunami warning after strong 7.
