There were also aftershocks, many at 7 of above and over eight hundred aftershocks of magnitude 4. The size of the earthquake on the Richter scale – the higher it is on the scale, the more destruction it can cause. Shock waves could be felt over the border in Pakistan, also felt in Bangladesh and Nepal. Two nuclear plants on the Pacific coast in F ukushima were automatically shut down. This displaced the water above in the Pacific Ocean causing a Tsunami wave to ripple radially outwards. In this instance it was the Eastern seaboard of Japan and the Island of Honshu that were vulnerable. This cause contamination of the sea and land, and force the evacuation of local residents.

Live footage of the actual earthquake – what impact did JUST the earthquake have? Pre release notes for Unit 4 Tectonics. Damage to roads through liquefaction made it difficult for people and emergency services to move around.

It was originally reported at a magnitude of 7. Business were put out of action for long periods causing losses of income and jobs. The coastline is also vulnerable, as the vast majority of people live on the coast of Japan.


SEE impact include primary and secondary Hazards. It was technically an aftershock from a larger earthquake in but the impacts were more severe. Focus of 17km below the earth’s surface which measured 7. By continuing to use this website, you agree to their use.

To monitor earthquakes, the Japanese Meteorological Agency operates network of about seismographs and seismic intensity meters. The yen could be in for further declines as the scale of the damage becomes known.

The tsunami is a secondary consequence of this initial movement. All Tokyo area trains were halted, while the shinkansen bullet train service was suspended. The depth of the focus – if it’s shallow, it can be more destructive. Liquefaction where the ground gets saturated and loses strength caused lots of damage to roads and buildings.

The warnings from the JMSA also helped save lives. In Tokyo, hundreds of concerned office workers tried in vain to make calls on jammed cellphone networks, some wearing hard hats and other protective headgear. At Fukushima the subsequent tsunami disabled emergency generators required to cool the reactors.

Communications were damaged and power lines brought down. There were several nuclear incidents but the most notable was 3 nuclear meltdowns at the Fukushima power plant.

As a result of the high frequency of Earthquakes in this area Japan has developed a high capacity to cope with both Earthquakes and tsunami. We can classify the effects of an earthquake into the following categories: The IAEA has rated the events at level 7, the same as Chenobyl, and the highest on the scale — meaning that there is a major release of radio active material with widespread health and earthquae effects.
