MEDC EARTHQUAKE CASE STUDY A LEVEL

The time of day – whether people are in their homes, work or travelling. Population density – the more people living in an area, the more likely that more deaths and casualties may arise. Level of development – whether it occurs in a rich or a poor country. Impact Japan was largely prepared for the earthquake and many buildings remained standing afterwards, but it was not prepared for the subsequent Tsunami. The official death toll report confirmed 15, deaths, 26, injured and 3, people missing across twenty prefectures.

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.

Case Study – Japan Earthquake & Tsunami 11/03/11 – Joe Blakey

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.

More thanbuildings suffered some form of damage. Much of the cultural heritage was destroyed incuding forts, palaces, temples and monuments with many of them being centuries old. Authorities unable to cope with magnitude of event so there is no accurate toll of injured.

In Iwate Prefecture a bridge collapsed and a building was washed away, with boats and cars swirling around in the rising waters. The situation has been further compounded by numerous aftershocks.

In additionbuildings totally collapsed and another nearbuildings partially damaged. A brave team of nuclear power plant workers battled bravely to prevent the nuclear reactors overheating completely and exploding. Distance from epicentre – the effects of an earthquake are more severe at its centre.

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.
