Concluding Remarks
• Relatively little damage given the event, and as compared
with 2004 earthquake
• Largest impact is on the Kashiwazaki NPP
– Major implications for NPPs worldwide
– Major impact on TEPCO operations / profits
– Impacts Japan electric supply this summer
• Brief shutdown of Japan auto industry, but recoverable
• Emphasizes economic impacts of even moderate sized
events in advanced economies
• Reinforces need for mitigation of foreseeable natural
hazards, and integrated risk management (eg, BCP, risk
transfer)
