On 11 March 2011 an earthquake measuring 9 on the Richter scale triggered a tsunami in North-East Japan, with 10-metre waves ravaging the coastal areas and causing the worst nuclear disaster since Chernobyl, with the explosion of the reactor of the Fukushima power station. The destruction of infrastructure, the shortage of fuel, and many power cuts to the capital make the situation extremely complex. TSF deployed from its base in Bangkok to provide its emergency communications facilities. The mission drew to a close due to the high risk of the nuclear alert.

Context

A record 9-magnitude earthquake hit the north-east of Japan on 11th March 2011 at 2.46pm local time. The resulting 10-meter tsunami that crashed into the eastern coast and swept away towns led to the worst nuclear accident since Chernobyl, when the Fukushima nuclear power plan was swamped and its reactor caught fire.

Reaching the affected areas proved to be very difficult owing to the petrol limitation and the heavy damage on the roads to the north. Significant areas of the country have remained without power and water for an extended period of time. Power cuts occurring even at the heart of the capital slowed down the operations. As of 11th March, landlines were unavailable in Sendai and some parts in Tokyo. The GSM network became over-saturated.

The government declared an atomic emergency amid growing international concern over its reactors, and thousands of people were evacuated. The uncertainty regarding the extent of the nuclear alert following the explosion of Fukushima nuclear reactor made the situation all the more complex.

Support to coordination

TSF deployed a team from its regional base in Bangkok to assess the needs in telecommunications and provide emergency telecommunications assistance. They carried satellite phones and terminals, as well as computer and IT devices.

The team worked in collaboration with the United Nations Disaster Assessment and Coordination teams (UNDAC) and the Ministry of Foreign Affairs of Japan (MOFA). On 15th March, TSF opened a wireless connection at the On-Site Operations Coordination Centre (OSOCC) based at the JICA Tokyo International Centre (Japan International Cooperation Agency), to strengthen information management and sharing.

Nevertheless, in light of the emergency nuclear situation, the Direction of TSF issued an evacuation order for its members on 15th March at 10pm GMT.
