This exposes high numbers of people to the hazards of tsunami. There were also aftershocks, many at 7 of above and over eight hundred aftershocks of magnitude 4. A Meteorological Agency official appeared on TV urging those affected by the quake not to return home because of possible tsunamis. Image courtesy of Wikipedia. Many countries such as the UK sent search and rescue teams to help search for survivors. Over the following three weeks there was evidence of a partial nuclear meltdown in units 1, 2 and 3; visible explosions, suspected to be caused by hydrogen gas, in units 1 and 3; a suspected explosion in unit 2, that may have damaged the primary containment vessel; and a possible uncovering of the units 1, 3 and 4 spent fuel pools.
Damage was caused in Tokyo and many injuries in the north where the quake was centred The yen fell sharply but recouped most of its decline several hours later. It was originally reported at a magnitude of 7. It detected the Earthquake and issued televised warnings just after the very rapid P-waves that arrived but before the more damaging S waves.

The upper 10m of the soil in this zone was also very vulnerable, as the waves amplified in this soil and caused liquefaction.
Over the following three weeks levep was evidence of a partial nuclear meltdown in units 1, 2 and 3; visible explosions, suspected to be caused by hydrogen gas, in units 1 and 3; a suspected explosion in unit 2, that may have damaged the primary containment vessel; and a possible uncovering of the units 1, 3 and 4 spent fuel pools. We can classify the effects of an earthquake into the following categories: A tsunami measured at anywhere from one meter to 7.
Richer earthquakke will be more likely to be able to predict, protect and prepare themselves from the effects of an earthquake. Interactive — how Japan had recovered one year on. Christchurch could no longer host Rugby World Cup matches so lost the benefits, e. The depth of the focus – if it’s shallow, it can be more destructive.
Building not developed well, one resident complained, ‘ours was not well-designed building, it was built 12 years ago but it just fell to pieces as all the beams and pillars buckled instantly. Japan had its emergency crews and the army on site very quickly after the event. Immediate power outages in Tokyo and eight other prefectures reportedly affected some 4 stduy homes. Liquefaction where the ground gets saturated and loses strength caused lots of damage to roads and buildings.
It was technically an aftershock from a larger earthquake in but the impacts were more severe. In Iwate Prefecture a bridge collapsed and a building was washed away, with boats and cars swirling around in the rising waters. In this instance it was the Eastern seaboard of Japan and the Island of Honshu that were vulnerable. The situation has been further compounded by numerous aftershocks. Responses are how countries react to an earthquake. Distance from epicentre – the effects of an earthquake are more severe at its centre.

Damage to roads through liquefaction made it difficult for people and emergency services to move around. It lasted 6 minutes.
We’ll assume you’re ok with this, but you can opt-out if you wish. This cause contamination of the sea and land, and force the evacuation studyy local residents.
Tectonics Case Study Facts. The Japanese government is among the best prepared in the world for disasters and has so far only made specific requests for help, such as calling for search and rescue teams. This information also plays a vital role as a trigger for the initiation of rescue and relief operations related to earthquake disasters JMA. It had 10, times more energy than the magnitude 6. There were also huge numbers of large sized aftershocks, as big as magnitude 6.
He told a news conference a large amount of damage had occurred in the northern Tohoku region. In response, 91 countries have offered aid, from blankets and food to search dogs and military transport. The Defence Ministry was sending eight fighter jets to check the damage, the agency said.
The Japanese government responded by sending in specially trained people such as the Self-Defence Forces, a domestic response. There were 7 foreshocks, including a magnitude 7.

There were also aftershocks, many at 7 of above and over eight hundred aftershocks of magnitude 4. When this pressure builds up and is released, it causes a rapid shift in the plates and a lot of energy to be release, in this case about the same as the annual energy output of the UK.
A Meteorological Agency official appeared on TV urging those affected by the quake not to return home because of possible tsunamis. In effect, Japan owes its existence to this boundary and the Islands are volcanic in origin.
