Analytics software has been developed to help scour information posted on social media to get a clearer picture surrounding an event such as a disaster according to a Japanese expert
It was just one of the outcomes of the recent earthquake disaster in Japan shared by Nomura Research Institute (Japan) corporate senior advisor, Sawaaki Yamada, in his International keynote address about ICT and disaster management at CeBIT 2011 in Sydney.
Following a magnitude 9.0 earthquake on March 11 in the Tohoku region of Japan, and the resulting 10-metre tall tidal wave that hit the coastline, the damage to Japan’s ICT infrastructure was both wide and costly, he said.
In the wake of the disaster, 33 per cent of fixed lines and 21 per cent of base stations were down in the Tohoku area, but through a quick response 99 per cent of fixed lines and base stations were restored soon after.
Loss of power was found to be the biggest cause of damage to ICT infrastructure, as well as congestion caused by a reduction in working facilities and increased demand.
Yamada highlighted that social media played a big part in the dissemination of information following the disaster.As such the afore-mentioned software was developed to speed up the process of analysing information.
Lessons learned by Japanese telcos include the need for a more robust mobile network, development of new disaster reporting technologies, and the adoption of diverse power sources.
A quick response in the face of a disaster was also emphasised by Yamada. It was this that helped restore the majority of telecommunication services in Tohoku following the disaster.
