Link to GCSE syllabus: A case study of a tsunami – its cause, effects and responses.
Case Study: The Tohoku Tsunami, Japan 2011
On the 11th March 2011 a powerful earthquake measuring 9.0 on the Richter scale occurred around 100km east of Sendai on Honshu, Japan, In just 30 minutes a wall of water up to 40m high hit the coast of north western Japan. It was followed in places by up to 9 additional waves up to 10m in height. 3000km of coastline was affected by the waves, which tore through coastal defences.

Causes of a tsunami (BBC bitesize)
The earthquake that triggered the tsunami occurred at a destructive plate boundary where the Pacific plate was being subducted (pushed under)the North American plate. A segment of rock around 200km long slipped suddenly and flicked upwards by around 5-10m. This sudden uplift displaced (pushed up) the water creating the tsunami.
- 200000 people killed
- 500km2 coastal plains hit, destroying farmland, settlements and communications.
- Ruptured gas pipes led to fires.
- Explosions at the Fukushima nuclear power plant- this led to nuclear contamination and the possibility of meltdown as the cooling systems failed.
- Electricity lost in 6 million homes, 1 million had no running water,
- Further problems were caused by heavy snow and blocked roads.
- 100,000 Japanese soldiers sent out to search and rescue.
- Specialist search and rescue teams flown in from overseas.
- Exclusion zone set up around Fukushoma, people evacuated from area.
- Longer term: Re-building, re construction. Port facilities rebuilt, tsunami defence system reconsidered and extended.
23:38 The Independent newspaper is quoting reports of tens of thousands of people missing. That's many times the official police estimates.
23:12 What appeared to be a relatively controllable problem at the Fukushima facility is starting to look more serious. Mark Hibbs, of the Carnegie Endowment for International Peace, said if the cooling systems were not repaired within 24 hours, the plant risked a “definite danger of a core meltdown", with the “ultimate worst-case” was a “Chernobyl scenario” with explosions destroying the reactor.
22:42 Second power plant at Fukushima starting to lose its cooling systems, according to Japanese officials.
22:10 Fukushima plant is still partly submerged in the floodwater.

19:41 BBC's science correspondent, Pallab Ghosh, claims the fishing boat trapped in what appeared to be a whirlpool would have been dragged to the centre and "pushed to the bottom of the sea" unless it could power away. Didn't look that powerful to me, but maybe that's why I'm not a science correspondent. Or perhaps he was getting a bit carried away.
19:40 The tsunami alert in Indonesia has now been dropped, according to the BBC's Kate McGeown in Jakarta. It appears that the Pacific Rim is being less badly affected than we had feared, happily.

13.07: Britons living in Japan have spoken of their terror.
Ellie Moe, 30, a mother of two originally from Hertford, was at home in Tokyo with her young daughters when the earthquake hit.
She initially couldn't contact her New Zealand-born husband Steven, 34, who had only this week returned from Christchurch where he had been visiting his parents in the wake of their earthquake.
Mrs Moe said:
Earthquakes have been on my mind a lot, and I've been really wondering when one will hit Tokyo. We have little ones fairly infrequently here, but this was the first that I was actually doubting if our building would hold up.
Thankfully I was at home with my two girls, aged three-and-a-half and 18 months, and when it started I thought it would be over with soon, but it got bigger and bigger.
I grabbed them and we sat in the hallway, away from the windows and anything that might fall. It just went on and on.
Everything was shaking and banging, doors were opening and closing and I could hear lots of things falling over, but thankfully no furniture fell down.
Afterwards we sat there glued to the ground, praying for my husband who works in the city in an older building with 5,000 people. Then the second one came, it seemed right away, just as big although not for as long.
My elder daughter Shanna was pretty scared but deals with situations like this by going to sleep and the baby, Ayala, I think thought it was a ride.
I wondered if we were meant to go outside somewhere in an event like this but i didn't know where.
Also I couldn't find any English information on our radio nor much on the internet so had to guess at the Japanese announcements.
It was certainly terrifying. My mouth was dry for hours afterwards and I felt nauseous. But I just keep thinking how much worse it would have been if it was centred under Tokyo. Only now are we realising the extent of the horror further north.

Richard O'Shea, 25, originally from Neath, South Wales, is also currently living in Tokyo, where he works as a teacher.
I was at school when it hit. First we got the children to go under the table, that was just standard procedure, but the force just continued to grow, it felt like the world was going to end.
The children were very well behaved when the quake was at its peak and I was quite scared.
I looked under the desk and there was a three-year-old boy playing with a toy banana as if everything was normal - I don't know why, but it really calmed me down.
Matthew Holmes, a 27-year-old from Nottingham, was at work in Shimokitazawa, west central Tokyo, when he felt the earthquake, which he described as being "like many shocks, joined up by a feeling of being on a wave".
Mr Holmes, who is teaching English after studying for a journalism MA at Sheffield University, said:
I was teaching a class at the time and it's the first time I've been under the table. People were genuinely worried when they told me to get down.
We're only on the second floor, and I thought they were looking after the uninitiated foreigner, but then they really seemed to hit a strange auto-pilot panic.
I have been in Tokyo for three years but never felt something like that. People in their 50s are telling me that neither have they.

12.42:Japan has told the U.N. nuclear wathchdog that a heightened state of alert has been declared at the Fukushima Daiichi nuclear power plant after Friday's major earthquake, the Vienna-based agency said.
Reuters reported that the International Atomic Energy Agency also said it had been told that the plant had been shut down and that no release of radiation had been detected.
Japanese media have reported separately that a leak was possible at the plant as water levels fell.
The World Meteorological Organisation says prevailing winds are blowing eastwards, away from the Japanese coast.
The IAEA is seeking further details on the situation at Fukushima Daiichi and other nuclear power plants and research reactors, including information on off-site and on-site electrical power supplies, cooling systems and the condition of the reactor buildings.
Nuclear fuel requires continued cooling even after a plant is shut down.

11.10: Stocks all round the world have been hit but the yen proved resilient to one of the bigger tremors the country has suffered. The FTSE is set for its worst ever week for almost a year.
Shares in European insurers fell sharply on Friday morning after the massive earthquake.

She told The Daily Telegraph via Skype that she was "quite close" to where the quake hit:
We were in school, talking to the kids when suddenly the entire school was swaying for 3 minutes. We noticed this one. There have been constant aftershocks ever since. The power went out with second or third.
There have been two aftershocks in the last thirty minutes. They're big. Crazy. We got off pretty lightly I think. Haven't heard from anyone in Miyagi, but it's meant to be much worse there.
Everywhere in our prefecture the power is out. Possibly all over Northern Japan. We have got no news but on the radio.
The phone network is still up - at least on 3G anyway - but we can't really call each other. Gas and water are still fine. The news here is there might be aftershocks for the next month.
Everyone is coping. There's no damage. The teachers say it's the biggest they've ever felt, but they're pretty calm. The big problem is the snow has come back. There's a full on blizzard and no traffic lights.
None of the shops have power. They're all chock full of people buying up food. No idea when power is going to come back.
It was meant to be graduation tomorrow but it isn't going to go ahead as planned. I am probably going to sleep under my table

We have set up a crisis centre in the Foreign Office to co-ordinate our response and offer advice to anyone concerned about relatives or friends in Japan. We are not aware of any British casualties at this time.
Our advice to those in Japan is to check immediate surroundings for fire, gas leaks, broken glass and other hazards, and open doors and windows to avoid being locked in if there are after-shocks.
British Nationals should also make contact with the British Embassy in Tokyo on +(81) 3 5211 1100 or the Consulate-General in Osaka +(81) 6 6120 5600 and monitor local TV and radio for evacuation information.
Radio stations in the Tokyo area that have emergency information in English include the US Armed Forces station at 810AM and InterFM (76.1FM).
British Nationals at evacuation sites should cooperate with the Japanese authorities and clearly identify themselves as British. Those connected with larger organisations such as companies, schools or church groups should also try to let these organisations know of their situation if possible.
Following tsunami warnings across the region our Embassies and Consulates are preparing to provide assistance. Rapid Deployment Teams are ready to travel immediately to the areas of most need.

This is the largest earthquake known in Japan. There have been seven earthquakes in Japan over magnitude 8 since 1891.
In 1923 in the great Kanto earthquake which measured 7.9, 147,000 people died so our expectation is that many people will be killed and there will be extensive damage. Fortunately for Tokyo it’s a bit further north than the great Kanto earthquake was, which means the damage in Tokyo is likely to be much less.
A Pacific wide tsunami has been generated, so that will be impacting other countries in the north Pacific in the coming hours.

Prof James Goff is Co-Director of the Australian Tsunami Research Centre and Natural Hazards Research Lab at the University of NSW:
This Japanese event was considerably larger, only 10 km deep [now revised by the USGS to 24km] and so we should expect a tsunami to have been generated by this.
Not surprisingly warnings and watches are in place. It would highly unlikely for a tsunami to NOT be generated.
Japan has a rigourous earthquake building code and excellent tsunami warning system and evacuation plans - this event will likely provide a severe test for all of them.
