Hawaii Island makes up of five volcanos of Kohala, Mauna Kea, Hualalai, Mauna Loa, and Kilauea. They are big shield volcanoes rising above the Pacific ocean floor and final two volcanoes provide a natural laboratory for the study of active volcanoes. Mauna Loa is the largest single volcano on earth. At the submmit is an oval-shaped Mokuaweoweo caldera, from which two rift zones extend to the southwest and northeast, and in the medial part are the longest lava tube systems in the world. Kilauea has been formed largely by eruption along southwest and eastern rift zones extending from Kilauea caldera at the submmit. On the eastern rift zone, spectacularly, the 1989-1974 eruption of Kilauea at Mauna Ulu crater formed the Mauna Ulu lava flow field. The 1983-1986 eruption of aa flows at Puu Oo crater, and the activities of pahoehoe flows during 1986-1990 at Kupaianaha crater and during 1991-recent at the Puu Oo has produced the Puu Oo and Kupaianaha lava flow field.

제주도는, 일반, "한국의 하와이"라고도 불리우고 있는데, 중앙에 한국제일의 명산 한라산이 우뚝 솟아 있는 이 섬은 틀림없이 으뜸 가는 관광지로 생각된다. 변화무쌍한 해안선, 한라산을 중심으로한 산악지대, 각지에 점재하는 세계에서도 유수의 대용암동굴 등의 풍부한 천연의 관광자원과 아울러 골프, 낚시, 수렵 등의 레저를 즐길 수 있는 것은 극히 매력적이다.(중략)

The accurate official map of air temperature does not exist for the Hawaiian Islands due to the limited number of weather stations on the rugged volcanic landscape. To alleviate the major problem of temperature mapping, satellite-measured land surface temperature (LST) data were used as an additional source of sample points. The Moderate Resolution Imaging Spectroradiometer (MODIS) system provides hypertemperal LST data, and LST pixel values that were frequently observed (${\ge}$14 days during a 32-day composite period) had a strong, consistent correlation with air temperature. Systematic grid points with a spacing of 5km, 10km, and 20km were generated, and LST-derived air temperature estimates were extracted for each of the grid points and used as input to inverse distance weighted (IDW) and cokriging methods. Combining temperature data and digital elevation model (DEM), cokriging significantly improved interpolation accuracy compared to IDW. Although a cokriging method is useful when a primary variable is cross-correlated with elevation, interpolation accuracy was sensitively influenced by the seasonal variations of weather conditions. Since the spatial variations of local air temperature are more variable in the wet season than in the dry season, prediction errors were larger during the wet season than the dry season.

It is widely assumed that climate change and other anthropogenically driven processes are having a serious impact on coastal environments. One such impact is saltwater intrusion into coastal aquifers, which has resulted in the loss of groundwater resources. The pattern of saltwater intrusion is strongly dependent on regional hydrogeological characteristics. This study reviews recent qualitative and quantitative research into this problem, and considers relevant case studies. In addition, the characteristics of the aquifers from two representative volcanic islands (Jeju Island, Korea and Oahu Island, USA) are compared. The fundamental theory of density-dependent flow used to model saltwater intrusion processes and the programs that are widely used to simulate saltwater intrusion based on density-driven problems are also investigated. It is expected that the knowledge gained from this review of previous studies can be used to help improve groundwater management practices in Korea and also to inform future interdisciplinary studies.

Kilauea volcano located in the southern part of Hawaii island chains has been formed by continuous and sporadic eruption activities from 16 century to September of 1982. Kilauea volcano was investigated from collecting the samples of basalt to identify the geochemical characteristics of the lavas. Olivine, clinopyroxene, plagioclase, and opaque minerals with glass groundmass are observed. Clinopyroxene formed glomerophopyritic texture with plagioclase and zoning texture was observed in some of plagioclase phenocrysts. Major elements such as $K_2O$, $P_2O_5$, $TiO_2$ increased with respect to MgO. $Al_2O_3$ and CaO show the kink on Marker diagram due to the crystal fractionation of plagioclase and clinopyroxene with plagioclase respectively. Olivine has a wide range of Fo% ranging from 60 to 90, and MnO and FeO in the olivine are decreased with increasing Fo% oppositely increased $SiO_2$, MgO, and NiO. Ni in the whole rock is controlled not only by the mode of olivine but also by the Ni abondance in the olivine.
