While not submissive International Atomic Energy Agency (Aiea) reported
Whether there was no damage to the nuclear installations in Japan after an 8.8 magnitude earthquake was recorded off the Kamchatka peninsula in Russia, coastal communities did not take risks and have evacuated on higher grounds or moving more inside.
UNDRR) confirmed. Although the authorities have now downgraded the threat through Japan, because waves of 1.3 meters (4 feet 2 inches) have been recorded, the council is that people remain in shelters until the danger decreases on continuous sea overvoltages.
“It’s very complex; We observe tsunami data in real time, so we need people to stay in the refuge until the end of the tsunami “,” said professor engineer of Tsunami, Professor Fumihiko Imamura of Tohoku University.
Mortal heritage
In the nation of the Asian island, memories are still raw from the earthquake and tsunami of March 11, 2011 which killed more than 18,000 people.
Last year, the magnitude 7.6 Noto Quake left around 500 dead and damaged 150,000 houses.
“” An earthquake of magnitude 8.8 is a very large earthquake “,” explained Kamal Kishore, special representative of the Secretary General of the United Nations for the reduction of disaster risks.
“As you go from the eight -to -nine magnitude, or seven to eight, at each stage, the strength of the earthquake increases exponentially. Thus, an earthquake which is eight of magnitude as opposed to seven would be 30 times larger. »»

Leur progrès peut être aussi rapide qu’un jet de passagers et peut être suivi par des capteurs de changement de pression en mer profonde, ou tsunameters, qui sont connectés à des bouées de surface qui relaient les informations en temps réel aux satellites. These data is then modeled by national weather centers, influencing if alerts are issued.
“It is a real threat because tsunamis travel very quickly from one coast to another,” continued Mr. Kishore. «Le tsunami de l’océan Indien de 2004 a été l’un des plus dévastateurs de notre mémoire, qui a voyagé depuis la côte de l’Indonésie aux côtes sri-lankaises en un peu plus d’une heure.»
Lessons learned
In addition to the coordination role of the UNDRR in the global early alert system, other United Nations entities also closely involved include the world meteorological organization (Wmo) and the intergovernmental oceanographic commission of the United Nations Education, Science and Culture Agency (UNESCO-IOC).
The role of the IOC is essential to ensure that countries that use tsunami monitoring instrumentation follow the same standard.
These efforts comply withThe first warnings for all
Today, one in three people – and mainly in the least developed countries and the development states of small islands – does not have access to adequate multiple early alert systems.
“There are countries separated by thousands of kilometers of ocean, but they are affected by the same danger,” he continued.
