"Alert earthquake: An earthquake was detected in the northwestern region. Be prepared for very strong shocks" thanks to technology developed in Japan, mobile phones can warn people and help organize aid.
This "early warning device" developed by the Japanese Meteorological Agency has yet to be perfected "a message sent on 25 August 2009 at 06H37 to mobiles of thousands of people in eastern Japan was a false alarm, but the system is unique in the world.
Such warnings were once reserved for institutions, nuclear power and railway companies. Since October 2007, are sent to phones, are broadcast by the media and broadcast over loudspeakers in public places in Japan.
The alert may also resonate in every home, thanks to specific appliances offered by electronics manufacturers, security companies or managers of buildings.
The result of years of research, the system proposed by the Meteorological Agency to detect early signs of an earthquake and instantly assess their destructive potential.
The device plays with the differences in speed of propagation of different waves emitted by an earthquake. Thanks to the speed of telecommunications networks, early warning can be given just before they hit the waves more deadly.
Experts estimate that the number of victims of the earthquakes could be reduced by 90% if people available for only ten seconds off the gas, cover under a table, open the door, etc..
Only major earthquake alerts are communicated to the general public to avoid panic in a country where small earthquakes are extremely common and effective earthquake-resistant techniques.
When tragedy occurs, the Japanese rely on telecommunications to reduce its severity, by tracking devices of the damage and casualties as conceived by NTT Comware.
This portable device that includes a computer, a projector and a stylus in addition to mapping software linked to a database, is aimed at local authorities.
Allows record events in real time, quickly, easily and immediately transmitted to crisis management centers.
"The operator has only to select a small image (fire, landslide, tsunami, etc.). In a paddle with the stylus and bring to a map projected on a table," Katsuki said Aki, NTT Comware.
"Instantly, you get a view of the situation can escalate, filter the display, assessing risks around measure distances, display the number of people potentially affected and different indication necessary for organizing assistance," explains.
The data located and dated, including photos and videos can also be brought directly to the ground from surveillance cameras, fire detectors, gas sensors and other equipment, or be aimed at rescuers equipped with mobile phones equipped with a module satellite tracking (GPS).
Computerized, the data dictionary is available immediately from more distant places.
The 47 prefectures are to be equipped with this device in the perspective of an earthquake of great magnitude greater than 7, which is highly likely to occur in coming decades in several regions, including Tokyo.
