The Scales of Disaster (Part Deux)
Kobe Earthquake, Japan, 1995 [MAP] [Background]
Some 9 years after the Chernobyl disaster, an Earthquake with a magnitude of 7.2 shook Japan and flattened the port city of Kobe. This VIDEO displays images from the aftermath of the Earthquake which killed over 5000 people. One very clear scaled interest here would be the Richter scale by which the magnitude of earthquakes is measured. This link gives an easy reading explanation of the Richter scale and the effects that may accompany the range of magnitudes. Kobe at 7.2 is in a category of earthquakes that according to this site occurs around 15 times a year, so one matter for you may wish to investigate is why are the scale of impacts seen in Kobe not more common?
This was a disaster of tragic proportions there can be+ no doubt, but what has become of Kobe now close to 15 years since this earthquake? Very noticeable in the case of Kobe when compared to Chernobyl, is that when you simply type the name into google, Kobe returns some results that are not solely focused on this disaster, while Chernobyl returns nothing but reports and views on its disastrous events. Kobe's is featured in an online Japan travel guide, which displays several areas of interest and a present day picture of a thriving port city and ranks Kobe 11/111 destinations worth visiting in Japan. There is a mention in the guide of the events of 1995, and a memorial is among the tourist attractions, but Kobe has been entirely rebuilt and moves on looking towards the future.
Chernobyl vs Kobe
These are two tragic events that have death tolls that reach well into the thousands and have cost fortunes in their aftermaths. The key scale by which Chernobyl extends beyond Kobe in its impacts however, is time. These examples were picked to demonstrate to you the enormous scale of destruction that both man and nature can bring to the world, but as stated at the beginning of part 1 these are older examples chosen to allow you to see how the impacts of disasters can develop over time. In the case of Kobe, the earthquake and the lives lost will never be forgotten, but the city has been brought back to life. The events of Chernobyl in contrast continue to cause political, financial and (depending upon your sources) medical issues to this day, and will continue to do so well into the future.
One final thought for you. Watch this video on the Earthquake we experienced in the UK a few years back which centred in Lincoln. The BBC reporter for this story use the terms 'disaster' to describe the events. Compared to the disastrous events that have occurred in Kobe and Chernobyl, in your opinion, can this relatively small scale incident really class as a disaster? And whatever your stance, why?
SHIFT HAPPENS!
Its an effective piece that just stirs some useful thoughts about the wonder that is scale

We'll call this, the scales of ignorance- its just funny to be honest
This hopefully justifies the need for our chosen proffesion!

MAPS!!! Looking at scales of maps and different types of maps.
Because the Earth is round, and maps are flat, it is impossible to create a map with a perfect scale. Some parts of the map will be too large, while others will be too small. The larger a territory represented by a map, the greater that the distortions in scale will be.
There are many benefits to using a graphic scale. Firstly and most importantly it is a straight forward and easy way to determine scale. Secondly, if a map’s size is enlarged or decreased the scale is also enlarged or reduced, meaning that it is still accurate. The map adjacent shows a graphic scale.
The verbal method of depicting scale simply uses words to describe the ratio between the maps scale and the real world. For example, a map might say something like “One Inch equals one hundred and fifty miles”. Calculating scale on a map using the verbal method is easy. Simply measure the distance on the map and then follow the verbal directions to calculate the actual distance. this is what you would expect to find in the corner of your map if it was made using the verbal method of scale:
- Road (1:250,000 scale) – Designed for road users. They have green covers; 8 sheets cover the whole of Great Britain.
- Tour (c.1:100,000 scale except Scotland) – One-sheet maps covering a generally county-sized area, showing major and most minor roads and containing tourist information and selected footpaths. Tour maps are generally produced from enlargements of 1:250000 mapping. Several larger scale town maps are provided on each sheet for major settlement centres.
- OS Landranger map (1:50,000 scale) – The "general purpose" map. They have pink covers; 204 sheets cover the whole of Great Britain. The map shows all footpaths and the format is similar to that of Explorer, albeit with less detail.
- OS Landranger Active map (1:50,000 scale) – select OS Landranger maps are available in a plastic-laminated waterproof version, similar to the OS Explorer Active range. As of October 2009, 25 of the 204 Landranger maps were available as OS Landranger Active maps.
- OS Explorer map and Outdoor Leisure (1:25,000 scale) – Specifically designed for walkers and cyclists. They have orange covers, and the two series together contain 403 sheets covering the whole of Great Britain (the Isle of Man is excluded from this series). These are the most detailed leisure maps that Ordnance Survey publish and cover all types of footpaths and most details of the countryside for easy navigation. The Outdoor Leisure series complement the OS Explorer Map, showing areas of greater interest in England and Wales (e.g. Lake District, Black Mountains) with an enlarged area coverage. It appears identical to the Explorer, except the numbering and a little yellow mark on the corner (relic of the old OL series). The OS Explorer maps, together with Outdoor Leisure, superseded the previous Pathfinder maps (green covers) which were numerous in their coverage of the country.
- OS Explorer Active map (1:25,000 scale) – the OS Explorer and Outdoor Leisure maps are also available in a plastic-laminated waterproof version.
Also a threat to the OS operation is the use of technology and GIS. The examples that were used above to describe the various scales given on a map were taken from a GIS piece of software called Google Earth, this software is free to download and can you used to look at any place on the globe either in map form, or with limited results aerial / satellite photos. There are also a limited number of terrain maps showing the various terrain of an area which is layered over a street map.
So that concludes this section on maps and thier scales. We hope you have gained a valuable insight into maps, thier history and how they are "scaled" when created. There are many many many more types of map, and you can pretty much create a map to show whatever you want based on a country, such as rainfall, population, politics, the list goes on....literally anything can be put on a map! Why not try and think of some more things that could be put on a map.

The Scales of DISASTER!
As recently as just a couple of weeks before this post, issues surrounding the management of Chernobyl were raised by Ukraine's President. This article displays the scale of impact the Chernobyl disaster is still having today as a very much international scaled issue with links to the US and Europe as a broad entity. The level of funding required still now to safely seal the reactor at Chernobyl close to 24 years since the initial accident demonstrates vast scale of impact that this disaster has had, and will continue to have for a long time to come.
The after effects of the Chernobyl disaster can still be seen at work very clearly today and hopefully with the links we have provided you could begin to help you investigate this matter further if you wish as there is so much to discover about this issue beyond mere matters of scale.

Meanings of Scale
Cartographic Scale; this refers to the depicted size of a feature on a map relative to its actual size in the world.
Analysis scale; this refers to the size of the unit at which some problem is analysed, such as at the county or state level.
Phenomenons Scale; this refers to the size at which human or physical earth structures or processese exist, regardless of how they are studied or represented.
Although the three referents of scale frequently are treated independently, they are in fact
interrelated in important ways that are relevant to all geographers and the focus of research or some. For example choices concerning the scale at which a map should be made depend in part on the scale at which measurements of earth features are made and the scale at which a phenomenon of interest actually exists
Issues of scale have always been central to geographic theory and research. Advances in the understanding of scale and the ability to investigate scale-related problems will continue, particularly with the increasingly common representation of geographic phenomena through the medium of digital geographic information (Goodchild and Proctor 1997)

The scales of......The Recession (Part 2)
In the previous post we used an article relating to empty store space in the UK, so what better way to link into our local area of Leicester than look at the same issue in this fine city. 'One in seven shops in city centre empty' was an article released by the Leicester Mercury in May 2009. At the same time there has been huge investment in the old Shires shopping centre, now The High Cross which has brought more big name stores into the city. In the majority of cases the common pattern has been the closure of small independent stores coupled with the introduction or often expansion of larger chains. On this local scale, as well as the previous national scale you can observe small scale stores being lost while larger scale players are able to stave off the challenges of the recession far better. As such, scale appears to play a key role in succesful business in times of economic hardship.
One independent store lost in Leicester's city centre however, was one store within the UK's largest independent entertainment retailers chain, Zavvi. This web based electrical entertainment retailer which bought out Virgin records high street store chain had 114 stores stores in the UK plus 11 in Ireland. However, 'The end of the road for Zavvi stores', came despite the scale of Zavvi's operation. Zavvi as a high street store is no more across the UK, now just maintaining its original web-based operation.
The Scales of......The Recession (Part 1)
This post along with Part 2 which will follow shortly will look to demonstrate the different levels on which the Global recession has had an impact. Looking at individuals, companies, cities, counties and the globe, not only will we look to demonstrate the scales on which the recession has hit, but also to demonstrate how these varying scales are linked together. In this first post we will look to tie together the Global and National scales
So first of all, for any readers outside of the UK, and those who do live here but have been living in a bunker for the last two years or just haven't noticed, here is a short article and attached video from The Telegraph investigating how, 'High streets have been left empty by the recession' , in the UK. The first tie directly coming from the article is the link to global phenomenon that is the internet as a potential cause of the loss of stores; and also something which may have now taken away demand for the high street store in the long run. The internet opens up individuals market options to a whole host of global chains such as Amazon who may have started trends towards internet sales and now more budget sellers such as CDwow among others. So, aside from the crippling global recession, global actors have driven the UK's high street further towards obscurity.
Hopefully this has provided some nice Global-National scale links for you all. But now lets flip the focus round, here is another article taken from The Guardian, 'Recession "threatens UK effort to tackle global warming"' . (Please note that the central theme here is more important in this case than spending too long reading the whole article.)
Bringing the first article again into the equation, here we have global factors impacting upon UK markets, reducing sales and taking them overseas- and as a result the UK's stance on the very global matter (the clues in the name) of Global Warming is in danger of being effected in potentially globally negative ways. Now, if the recession within the UK were infact to prove to have negative impacts upon climate change legislation, then Global influences upon the UK may turn around to have very global results. As such, in this case alone (and there would be many other avenues through which to demonstrate a similar point) we hope to have demonstrated the links between global and national scales in the impacts of the current recession.
In Part 2 which will follow shortly, we will tie this example into local and individual case studies within the UK to hopefully build a full picture of the scales of the recession.
