World's largest nuclear power plant restarts in earthquake-prone region

Japan's Kashiwazaki-Kariwa, the world's largest nuclear power plant, is set to restart despite its location in a high-risk earthquake and tsunami zone. The plant was shut down after the 2011 Fukushima disaster, which involved meltdowns in three reactors due to cooling system failure after a major earthquake and tsunami. Globally, about 20% of nuclear reactors are in seismically active areas. Critics raise concerns about earthquake safety at plants like Onagawa in Japan and Diablo Canyon in the US, while India's Tarapur and Armenia's Metsamor also face seismic risks. Germany has phased out nuclear power.
