On This Day... 12 March 2011

On this day in 2011 the Fukushima 1 Nuclear Power Plant, Futaba District, Japan, suffered a meltdown and explosion releasing radioactive material into the environment. 

On 11 March 2011 a magnitude 9.0 earthquake and tsunami struck approximately 70 kilometres east of the Oshika Peninsula  off the northeast coast of Japan. Units 4, 5 and 6 had been shut down prior to the earthquake for planned maintenance.The remaining reactors were shut down automatically after the earthquake, and the remaining decay heat of the fuel was being cooled with power from emergency generators. 

The tsunami generated by the undersea earthquake resulted in waves of up to 14 meters. The reactors were designed to handle up to 5.7 meters and the tsunami which hit the plant disabled emergency generators required to cool the reactors. 

The events at Fukushima have been rated at Level 7 (major release of radioactive material with widespread health and environmental effects r­equiring implementation of planned and extended countermeasures) on the International Nuclear Event Scale.

On This Day... 22 February 2011

On this day in 2011 The City of Christchurch, New Zealand was devastated by a magnitude 6.3 earthquake.

185 people perished and thousands were left homeless when the magnitude 6.3 earthquake struck the largest city on the South Island of New Zealand and New Zealand’s third largest urban area.

The earthquake caused liquefaction of the ground which combined with tremors brought down many of Christchurch’s biggest structures including the historic cathedral spire.

The quake struck at 12.51pm and greater loss of life was avoided due to the earthquake’s timing being during daylight hours whilst residents of the city were not asleep and were going about their business.

Damage from the earthquake is estimated at between NZD$20-$30 Billion.
