Most of the historic hot springs are artesian wells in Korea. However, many boreholes have been drilled due to the shortage of hot water, and hot water is now being pumped by submersible pump installed at most of hot spring areas. The distribution of boreholes are expected to be related to the geological structure, and the study was carried out to interpret the relationship between two factors. The distributional maps of boreholes were made and the geological structures were interpreted at eight hot spring areas. Some distributions of boreholes have no special direction, and these are not related to the geological structure at Dogo, Suanbo, and Deoksan. The others are consistent with the direction of the geological structure at Goseong, Onyang, Sokcho, Yuseong, and Bugok.

Field learning have not well performed in elementary school for various reasons, in spite of the benefits of field study. Absence of suitable geological field courses for elementary science education is one of several reasons The purpose of this study is to develop learning materials for the field geology in Hampyeong region and apply them to the geological related units for elementary science education. The 5 observation sites for the field geology learning in study area include various rocks and geological structure such as granite, gneiss, conglomerate, sandstone, mudstone, plant fossil, fold, fault and weathering phenomenon changing rocks to soil. This study area is suitable place for the field geology learning of elementary science education in Kwangju and Chonnam province because of convenience access, fresh outcrops and distribution of various geological learning materials as rocks and structure.

Urban geology is the study of urban geologic environments to provide a scientific basis for rational land use planning and urban development and provides information on geologic environments as a basis for city planners. Based on AEG recommendations, urban geological studies covered the urbanism and historical backgrounds, geological setting, engineering geological constraints and environmental assessments of understudied cities. The aim of this study is to provide a good view of urban geology of Tabriz city the capital of East Azerbaijan province in Iran. The topics of discussions about Tabriz city urban geology are included geologic (geomorphology, geology, climatology and hydrogeology), engineering geological (earthquake, landslide and geotechnical hazards investigations) and environmental characteristics (air, soil and water hazards assessment).The results of the urban geologic studies indicated that Tabriz city in terms of engineering geological and environmental constraints is at high risk potential and in terms of seismic activity and landslide instability is highly potential. In terms of air, soil and water pollution there are many important environmental concern in this city.

International standards recommend typical phases to be included within any national program for the development of a geological repository dedicated to disposal of the high level radioactive wastes generated in countries using nuclear power. However, these are not universally applicable and the content of each of these phases may need to be adapted for each national situation and regulatory and institutional framework. Several national geological repository programs have faced failures in schedules and have revised their programs to consider an adapted phased management approach. The authors have observed that in the case of those countries in the early phases of a geological repository program where boundary conditions have not been fully defined, international recommendations for handling delays/failures in the national program might not immediately help. This paper considers a case study of the influences of the national context risks on the current planning schedule of the Romanian national geological repository. It proposes an optimum solution for an integrated response to any significant adverse impact arising from these risks, enabling sustainable program planning.

In this study, the city of Osijek is used as a case study area for low to medium seismicity regions with deep soil over deep geological deposits to determine horizontal PGA values. For this reason, we propose new regional attenuation equations for PGA that can simultaneously capture the effects of deep geology and local soil conditions. A micro-zoning map for the city of Osijek is constructed using the derived empirical scaling equations and compared to all prior seismic hazard estimates for the same area. The findings suggest that the deep soil atop deep geological sediments results in PGA values that are only 6 percent larger than those reported at rock soil sites atop geological rocks. Given the rarity of ground motion records for deep soils atop deep geological layers around the world, we believe this case study is a start toward defining more reliable PGA estimates for similar areas.

A total of 594 reservoirs (17%), which are managed by KRC, equipped with earthquake-resistant facilities whereas remaining ones did not. In addition, reservoirs were placed without the effect of geological structures (i.e., fault and lineament). Therefore, development on technique for alleviating the potential hazards by natural disasters along faults and lineaments has required. In addition, an effective reinforcement guideline related to the geological vulnerabilities around reservoirs has required. The final goal of this study is to suggest the effective maintenance for the safety of earth fill dams. A radius 2 km, based on the center of the reservoir in the study area was set as the range of vulnerability impacts of each reservoir. Seismic design, precise safety diagnosis, seismic influence and geological structure were analyzed for the influence range of each reservoir. To classify the vulnerability of geological disasters according to the fault distribution around the reservoir, evaluation index of seismic performance, precise safety diagnosis, seismic influence and geological structure were also developed for each reservoir, which were a component of the vulnerability assessment of geological disasters. As a result, the reservoir with the highest vulnerability to geological disasters in the pilot district was analyzed as Kidong reservoir with an evaluation index of 0.364. Within the radius of 100km from the epicenter of the Pohang earthquake, the number of agricultural infrastructure facilities subject to urgent inspections were 1,180 including reservoirs, pumping stations and intakes. Four reservoirs were directly damaged by earthquake among 724 agricultural reservoirs. As a result of the precise inspection and electrical resistivity survey of the reservoir after the earthquake, it was reported that cracks on the crest of reservoirs were not a cause of concern. However, we are constantly monitoring the safety of agricultural facilities by Pohang aftershocks.

본 연구는 과학기술에 대하여 우리 사회가 갖는 신뢰와 불신 인식을 측정하고자 하는 것이 목적이다. 과학기술에 대한 신뢰와 불신을 살펴보는 것과 동시에 지질자원기술에 대하여 신뢰와 불신을 함께 살펴보았다. 또한 과학기술과 지질자원 기술에 대한 신뢰와 불신의 수준을 비교함으로써, 지질자원기술의 신뢰성을 높이는데 필요한 시사점을 도출하고자 한다. 본 연구는 수도권에서 근무하고 있는 20세 이상의 남녀 직장인들을 대상으로 과학기술 및 지질자원 기술에 대한 신뢰와 불신에 대해 설문조사를 실시했다. 분석 결과, 전체적으로 응답자들은 과학기술 및 지질자원 기술에 대한 신뢰를 보통 수준 이상으로 가지고 있는 것으로 나타났다. 응답자의 성별이나 연령대에 따라서는 과학기술 및 지질자원 기술에 대한 신뢰 및 불신에 대한 차이가 나타나지 않았다. 과학기술과 지질자원 기술에 대한 신뢰 및 불신에 대한 차이를 살펴본 결과, 응답자들은 지질자원 기술보다 과학기술에 대한 신뢰도 점수가 좀 더 높게 나타남을 알 수 있었다.

다양한 지질명소가 국내에 분포하고 있음에도 불구하고, 지질명소를 야외학습장으로 활용하지 못하고 있다. 이 연구의 목적은 상세한 지질조사를 통해 서낭바위 일대를 야외학습장으로 활용 가능하게 하는데 있다. 서낭바위는 강원도 죽왕면 송지호해수욕장 부근에 위치하며, 송지호에서 남동쪽으로 약 1km 떨어져 있다. 서낭바위 일대는 중생대 백악기 속초화강암과 이를 부정합으로 충적층이 덮고 있는 단순한 암석분포를 보인다. 서낭바위 일대는 초중등학생과 일반인들에게 화강암 암상, 구성광물, 풍화과정뿐만 아니라, 절리(N50E/80SW, N40W/84NW), 단층(N42W/83SW), 엽리(N32E/54SE), 암맥(N35E/40SE, N26W/63SW)과 같은 지질구조와, 토르, 타포니, 그루부, 나마와 같은 지형들을 학습할 수 있는 장소이다. 그러므로 서낭바위 일대는 작은 규모의 공간에서 여러 지질 및 지형학적 현상들을 학습하고 서낭바위의 성인을 토론할 수 있는 최적의 야외학습장이다.

The 'Fault' has been common interests to the structural geologists, geotechnical engineers and civil engineers. The 'Fault' is very important factor to evaluate to the geotechnical stability. In this paper, geological origin and classification of faults with structural geological features are described. These geological characteristics of faults are useful to understand and detect of faults for engineering practice.
