- Case study: Japan tsunami 2011
- What happened?
- Friday 11 March 2011 at 14:46, an earthquake of magnitude 9.0 on Richter scale occurred.
- The epicenter was 30 km below the pacific Ocean seabed and 129 km off the east coast of Honshu, Japan.
- It was at the point where the Pacific tectonic plate slides beneath the North American plate.
- This triggered a tsunami
- High, powerful waves were generated and travelled across the Pacific Ocean
- The area worst affected by the tsunami was the east coast of Honshu in Japan
- Main impacts
- Infrastructure
- the waves travelled as far as 10 km inland in Sendai
- the tsunami flooded an area of approx. 561 square km
- ports and airports in Sendai were damaged and closed
- the waves destroyed protective tsunami seawalls at several locations
- The massive surge destroyed three- storey buildings where people had gathered for safety
- The area worst affected by the tsunami was the east coast of Honshu in Japan
- a state of emergency was declared at the Furushima nuclear power plant, where cooling systems failed and released radioactive materials into the environment .
- In July, TEPCO, the Tokyo Electric Power Company, admitted that about 300 tons of radioactive water continued to leak from the plant everyday into the pacific Ocean
- social and economic:
- four years after the quake, around 230,000 people who lost their homes were still living in temporary housing
- The total damages from the earthquake and tsunami are estimated at $300 billion (approx. 25 trillion Yen)
- The number of confirmed deaths as of 10 April 2015 is 15,891. More than 2,500 people are still reported missing
- Infrastructure
- Responses to the disaster
- The country recently unveiled a newly-installed, upgraded tsunami warning system
- Earthquake engineers examined the damage, looking for ways to construct buildings that are more resistant to quakes and tsunamis. Studies are ongoing
