Two hour-long programmes recounting the triple disaster that rocked Japan will air back-to-back this Sunday on Discovery Channel. Megaquake: Hour That Shook Japan outlines the events surrounding the 9.0 magnitude quake, the biggest to strike Japan in 140 years, and the deadly aftermath that crippled the nation. The programme features exclusive footage, first-person accounts and analysis by experts. It will be followed by Emergency in Fukushima, tracing the dramatic struggle to avert a full nuclear meltdown at the Fukushima Daiichi nuclear power plant. Megaquake premieres on Sunday at 9pm, followed by Emergency in Fukushima at 10pm on Discovery Channel.
