Tsunsmi Flashcards
Earthquake : where, when and how
On Friday 11 March 2011 at 14:46:24, an earthquake of magnitude nine on the Richter scale occurred. It was at the point where the Pacific tectonic plate slides beneath the North American plate. The epicentre was 30 kilometres below the Pacific Ocean seabed and 129 kilometres off the east coast of Honshu, Japan.
Tsunami : how and where was most affected
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 ) (3)
The waves travelled as far as ten kilometres inland in Sendai.
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.
Social impacts (3) of teh Japan tsunami
Four years after the quake, around 230,000 people who lost their homes were still living in temporary housing.
6152 people injured, 15894 people, 130927 people displaced. Fujiuma dam failed and collapsed washing away houses and killing at least four people
450, 000 people left homeless

Responses to build capacity and reduce risk 2
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 earthquakes and tsunamis. Studies are ongoing
Economic impacts
The total damages from the earthquake and tsunami are estimated at $300 billion (about 25 trillion yen).
2126 Road, 56 bridges, 332,395 buildings, and 26 Railways destroyed or damaged
impact of the tsunami on teh power plant
A state of emergency was declared at the Fukushima nuclear power plant, where a cooling system failed and released radioactive materials into the environment.
In July 2013, the Tokyo Electric Power Company (TEPCO), admitted that about 300 tons of radioactive water continued to leak from the plant every day into the Pacific Ocean.

japan warniing tsunai
Japan’s earthquake early warning system, which uses seismometers and other sensors to detect seismic activity and issue alerts, was able to provide up to 90 seconds of warning before the 2011 earthquake struck. This allowed many people to evacuate buildings and move to higher ground before the tsunami hit.

Natural disasters
Catostrophic event caused by natural processes such as earthquakes or tsunamis. causes widespread damage or loss of life, such as earthquakes, hurricanes, floods, tornadoes, wildfires, and volcanic eruptions.
earthquake
An earthquake is a sudden and rapid shaking of the ground caused by the movement of tectonic plates
