As abnormal weather events due to climate change continue to rise, landslide damage is also increasing. Given the substantial time and financial resources required for post-landslide recovery, it becomes imperative to formulate a proactive response plan. In this regard, landslide susceptibility analysis has emerged as a valuable tool for establishing preemptive measures against landslides. Accordingly, this study conducted an annual landslide susceptibility analysis using the history of landslides that occurred over many years in the Jeolla region, and analyzed areas with a high potential for landslides in the Jeolla region. The analysis employed an ensemble model that amalgamated 10 data-based models, aiming to mitigate uncertainties associated with a single-model approach. Furthermore, based on the cumulative data regarding landslide susceptible areas, this research identified regions vulnerable to recurring landslide damage in Jeolla region and proposed specific strategies for utilizing this information at various levels, including local government initiatives, adaptation plan development, and development approval processes. In particular, this study outlined approaches for local government utilization, the determination of adaptation plan types, and considerations for development permits. It is anticipated that this research will serve as a valuable opportunity to underscore the significance of information concerning regions vulnerable to recurring landslide damage.

This study provides considerations for quantitative risk assessment of landslide on GIS technology. It shows how the landslide possibility analysis is linked by GIS modeling to provide loss estimation tools for landslide hazards in support of socio-economic loss reduction efforts. Those risk assessment results can deliver factual damage situation prediction to policy making for the landslide damage mitigation.

산사태는 전 세계적으로 매년 큰 재산 피해를 야기하는 자연 재해로 알려져 있다. 국내에서도 기후 변화의 영향으로 산사태 피해가 증가하는 경향을 보이고 있으며, 이로 인한 피해를 줄이기 위해서는 산사태를 증가시키는 인자들을 파악하는 것이 중요하다. 따라서 본 연구는 충청북도 충주시에서 발생한 산사태 피해에 영향을 미치는 변수들의 중요도를 평가하기 위해 랜덤포레스트 모델을 활용하여 14개의 인자들 사이의 중요도를 분석하였다. 연구 결과, 모델의 성능은 AUC가 0.87로 높은 정확도를 보이며, 변수 중요도는 경사 방향, 경사, 계곡까지의 직선 거리, 고도 순으로 정해졌으며, 이는 경사방향과 경사 등의 지형인자가 암종과 유효토심과 같은 지질과 토양인자보다 산사태 피해에 더 큰 영향을 미친다는 것을 시사한다. 이 연구 결과는 산사태 피해 예측지도의 제작 및 산사태 피해 감소에 초점을 맞춘 연구에 기초 자료로서 활용될 수 있을 것으로 기대된다.

2002년의 루사, 2003년의 매미로 강원도에는 산사태 및 토석류 관련 심각한 재해가 발생하였으며 이러한 피해는 하천도로에 막대한 피해를 주었다. 2002년 이후 재해대장을 살펴보면 강원도의 산악지형에 이러한 피해가 집중된 현상을 볼 수 있다. 최근 GIS를 활용하여 산사태 및 토석류 발생 지역을 예측하기 위한 많은 연구가 활발히 진행되고 있으며, 산림청에서 제작한 산사태 위험도가 대표적인 예이다. 본 연구에서는 하천도로에 막대한 피해를 입은 강릉지역의 산사태위험도를 GIS기법을 이용한 통계적 분석법과 결정론적 분석법을 적용하여 제작하였다. 2002년 이후 국도유지관리사무소의 재해대장과 현장조사를 통한 피해지점의 GIS DB를 구축하였으며, GIS 기법을 통해 제작한 산사태 및 토석류 위험지도의 정확성을 검증하였다.

본 연구는 산지토사재해의 인문사회적 피해강도 기준을 개발하기 위하여 산지토사재해로 피해를 입은 지역주민들의 산사태 방재사업에 대한 인식을 조사하고, 분석하는 것을 목적으로 한다. 우리나라는 전 국토의 약 64%가 산림지역이며 인구밀도가 매우 높아 산지개발을 통해 도시가 발전한 대표적인 산지-도시생활형 국가이다. 최근들어 우리나라는 산지토사재해로 인한 인명피해가 침수로 인한 인명피해를 넘어서는 등 산사태의 발생이 대형화되고 있다. 그 결과 2011년에는 서울시 우면산, 춘천시 등에서 예상하지 못한 산사태로 총 43명의 사망자가 발생하였고, 복구사업으로 막대한 비용이 소요되었다. 본 연구는 2011년의 주요 피해지역인 서울 우면산, 춘천시, 부산시, 동두천시를 대상으로 산사태의 피해현황과 피해요인에 대한 시설물 현장답사와 주민 설문조사를 수행하였다.

The whole death by disaster is totalized to 1,515 person from 1993 to 2004 year in our country. In this section life damages by landslide is totalized 357 people(about 24% of whole life damage). About 36 people are died by landslide(such as cutting area failure every year). Kangwon-do need a lot of interests and prevention because dangerous area that landslide occurrence is more than other area at summer localized downpour or thawing season and there is landslide occurrence possibility area more than other area. Kangwon-do area is higher than other area in natural disaster incidence and damage scale because topography and a lot of rainfalls by summer localized in Kangwon-Do than other area. In this study, dangerous area of landslide occurrence possibility is analyzed and compared Kangwon-Do with other areas in our country. as a result, every year we have experienced landslide occurrence and natural disaster. accordingly, we urgently need to prevent landslide occurrence and natural disaster by analy-zed source about landslide occurrence and condition of disaster in Kangwon-Do and suitable engineering method and construction work.

For development of landslide risk assessment techniques using GIS(Geographic Information System), this study classifies the category of socioeconomic factors. The landslide quantitative risk assessment performs first prediction of flow trajectory and runout distance of debris flow over natural terrain. Based on those results, it can be analyzed the factors of socioeconomic which are directly related to the magnitude of risk due to landslide hazards. Those risk assessment results can deliver factual damage situation prediction to policy making for the landslide damage mitigation. Therefore, this study is based on feature classification of the digital map ver. 2.0 provided by the National Geographic Information Institute. The category of factors can be used as useful data in preventing landslide.

The damages caused by landslides are increasing worldwide due to climate change. In Korea, damages from landslides occur frequently, making it necessary to develop the effective response strategies. In particular, there is a lack of countermeasures against landslides in cultural heritage areas. The purpose of this study was to spatially analyze the relationship between Buyeo-gun's cultural heritage and landslide susceptible areas in Buyeo-gun, Chungcheongnam-do, which has a long history. Nine spatial distribution models were used to evaluate the landslide susceptibility, and the ensemble method was applied to reduce the uncertainty of individual model. There were 17 cultural heritages belonging to the landslide susceptible area. As a result of calculating the area ratio of the landslide susceptible area for cultural heritages, the cultural heritages with 100% of the area included in the landslide susceptible area were "Standing statue of Maae in Hongsan Sangcheon-ri" and "Statue of King Seonjo." More than 35% of "Jeungsanseong", "Garimseong", and "Standing stone statue of Maitreya Bodhisattva in Daejosa Temple" belonged to landslide susceptible areas. In order to effectively prevent landslide damage, the application of landslide prevention measures should be prioritized according to the proportion belonging to the landslide susceptible area. Since it is very difficult to restore cultural properties once destroyed, preventive measures are required before landslide damage occurs. The approach and results of this study provide basic data and guidelines for disaster response plans to prevent landslides in Buyeo-gun.

This paper presents the disaster control due to flooding through the case study of Samwhadong, Donghae city, Kangwondo, broken out at 31, August 2002. In order to assess the characteristics of flood damage one must consider social and geological conditions, the factors of flood risk were derived based on GIS. For reduction of flood damage, flood hazard map was prepared for local residents. These information will support refuge activities, it would aid the reduction of flood damage.
