  • A moment magnitude 3.1 earthquake occurred in the Seoul metropolitan region (SMR), Korea, on 9 February 2010. The unexpected shaking attracted much attention and raised concerns about the seismic hazards and risks in the SMR, which was regarded as an area safe from any earthquake hazard. The SMR has a population of 25 million and is one of the largest metropolitan areas in the world. A shakemap for a scenario earthquake with magnitude 6.5 and focal depth 12 km implies that the SMR will be exposed to serious risk because of its large population and the high vulnerability of its buildings. Although the instrumentally recorded earthquakes discussed in this article cannot be classified as major events, they should not be discounted as insignificant. Considering the low seismicity, micro-earthquakes below the magnitude of a conventional seismic network can achieve would be used to estimate background information in the evaluation of earthquake hazards and risks.

  • The main purpose of this paper is to examine selectivity and rasons for move of internal migrants in Korea. There have only been a few studies available on the issues of selectivity and reasons for move of internal migration in Korea, mainly due to the lack of appropriate data. The main source of data for this analysis come from the raw data set of the 1997 Special Migration Survey conducted by the National Statistical Office. Analysis of selectivity of those who moved across the provincial boundary revealed that females, young adults, singles in their marital status and more educated are more likely to move. Among various reasons for move, employment related reason is the most important for all migration streams. But with different migration streams, diverse patterns are emerged. For those who moved into the Capital Region, employment related reason is outstanding. But those who moved out from the Capital Region, moved for employment as well as family related reasons. For movement within the Capital Region, housing related reason is equally important together with employment and family reason. The analysis also found that among individual attributes, age and marital status affect most significantly to the reasons for move. Education level and housing ownership are also important for explaining for variations in reasons for move.

  • The purpose of this study is to examine the transportation, equity and efficiency impacts of cordon pricing schemes in the Seoul Capital Region of Korea. Autos would be required to pay a toll of 2.000 Won each time they enter cordons around the CBD or the subcenters during morning peak periods. The imposition of the toll would produce a substantial decrease in traffic volumes within the cordons as well as throughout the Capital Region. The lower the income level of commuters is, the more the share of auto decreases and that of transit increases. For equity impacts, the welfare of commuters would increase or decrease according to the cordon pricing schemes but would produce progressive impacts irrespective of the schemes. However, the commuters who have the highest value of time would experience welfare gains and it would result in regressive impacts. The schemes would result in a substantial net social welfare gain for the efficiency impacts. When the toll is charged at the CBD cordon only, the net social welfare would increase more.

  • This study targets to recognize needs of spatial pattern analysis and to draw the relationship between relocation of Capital Region firms and population outflow in Capital Region through the regression analysis. The population outflow in Capital Region has moved to and around Yesan-gun and Asan-si. Also, such outflow is found to compose mostly one or two household members for their jobs. In addition to this study has analyzed to find effect factors through the Geographically Weighted Regression. The results of the analysis has confirmed that the most decisive factors affecting population flow from Capital Region to Chungcheongnam-do were population factors and transportation factors and others. Thus, the below policy implications could be derived and also may be applied toward Sejong City which are currently experiencing the relocating of Public sectors and new constructions. Firstly, the effect of Capital Region firms movement on population inflows could be better observed in small-scale towns like "kun" than larger-scale towns like "si.". On the other hand, people in Capital Region moved to larger-scale towns like "si" unlike the Capital Region firms. This difference implicates that people select their residence according to not only their jobs but also residential environment. Secondly, moving people from Capital Region to another region for their jobs are expected to appear more in a form of family units rather than individual units. Sejong city, where public organizations are being relocated, should recognize this particular Chungcheonnam-do phenomenon and be prepared to be more effectively used in perspectives of land use as well as urban planning.
