Satellite thermal infrared remote sensing is nowadays an important and efficient techniques to explore and monitor the thermal ground around active volcanoes or hot spring regions in the world due to unstable ground, land use restricted as a park and higher cost of ground observations. Landsat 8 OLI-TIR sensors images were used in this study to observe the thermal status of three hot spring areas in UAE for the first time in the year of 2017. We used Landsat 8 TIR band 10 to estimate land surface temperature using mono-window algorithm, Normalised directional vegetation index (NDVI) threshold method for emissivity, Stefan Boltzmann law for radiative heat flux and heat discharge rate using a relationship coefficient. The highest maximum land surface temperature (LST) was obtained about 43 °C, 40 °C and 27 °C, respectively in the area of Ain Faida (AF), Green Mubazzarah (GM) and Ain Khatt (AK) hot spring area. The LST was about 13 °C, 10 °C and 4 °C above ambient on the pixel (30*30 m) average temperature, although the point LST might be higher than these. The landcover shows about 77%, 95% and 87% area of bared or desert land, 21%, 4% and 13% of mixed region, respectively in the study area of GM, AF and AK hot spring. Fully vegetated area was found only in GM area about 5% of total study area. Water bodies were about 1% only in the study areas of GM and AF. The highest radiative heat flux (RHF) obtained about 68 W/m2, 83 W/m2 and 21 W/m2 respectively in the GM, AF and AK spring area in United Arab Emirates (UAE). Total radiative heat losses were estimated about 157 MW, 530 MW and 15 MW respectively in the three hot spring areas. Total Heat discharge rate (HDR) was estimated about 1013 MW, 3423 MW and 94 MW respectively from GM, AF, and AK hot spring area using the relationship coefficient HDR and RHF i.e., 6.49. The study shows that the LST and RHF was increased with decreasing NDVI value i.e., bared or desert shows higher value than vegetated. We can infer from this study that the satellite remote sensing could be used for estimating or monitoring the thermal components of hot springs in UAE and any other part of world in a cost effective and efficient way.

Petrographic analysis to rock samples located at Oma-Haruku hot springs was dominated by mudstone. Another alteration mineral types of the rocks in this area are quartz, aragonite/calcite and feldspar minerals. Petrographic analysis was supported by the XRD method. The method indicated that the alteration minerals content was generally dominated by the presence of aragonite/calcite with particle size of 0.05 - 2 mm, the abundance of 55% and the spread evenly. Based on such presence of aragonite/calcite, one can interpret that the origin rock was carbonate. Alteration minerals which were generally dominated by mudstone indicate that the type of hot spring area in Oma-Haruku is a type of high-temperature reservoir, namely > 175 oC. Therefore, the area is  potentially as geothermal field in Central of Moluccas.

Competitive Structure

This paper investigates the competitive structure of prices in a traditional hot springs resort area in Japan from a spatial econometric perspective. This perspective has not been addressed in hot springs—or “onsen” in Japanese—tourism areas, which have been gradually losing momentum due to the ageing of operators and diversification of leisure activities. The study area is one of the three oldest hot springs in Japan, the Dogo Onsen area in Matsuyama, where hotels and ryokans are clustered. First, we present a conceptual framework that characterizes two strategies, namely, differentiation and partnership strategies. Then, spatial error models are employed to test the hypothesis that spatial closeness intensifies price competition, while social closeness mitigates price competition. The estimation results reveal that our hypothesis was verified, in that the social network which has been nurtured for generations in the study hot spring area mitigates price competition, in comparison with the non-hot spring area in Matsuyama. Thus, good partnerships among local operators based on social networks should be more closely scrutinized for the revitalization of traditional hot springs areas.

Hot springs in the Alvord/Pueblo valleys in southeastern Oregon are analogous to Basin-and-Range hydrothermal systems where heat source and permeable pathways are met through crustal thinning. Silica sinter deposition at Mickey Springs, Alvord Valley, predates the late Pleistocene high stand of pluvial Lake Alvord. At Borax Lake, Pueblo Valley, sinter deposition occurred during the Holocene. This study examines the evolution of springs at Mickey Springs, where three morphologies of sinter are present: (1) basalt clasts surrounded by sinter in interbedded conglomerate and sandstone, (2) pool-edge and aprons of sinter surrounding depressions (12–32 m diameter), and (3) quaquaversal sinter mounds with pool-edge sinter. The oldest sinter occurs in silica-cemented conglomerate and sandstone, where deposition occurred prior to 30 kya. Deposition around broad depressions and mounds occurred after 30 kya but before water levels began to rise in pluvial Lake Alvord. Thermoluminescence dates suggest sinter deposition ceased before 18 kya when silt and clay filled inactive vents and buried aprons. A few mounds hosted active springs after sinter deposition ceased but while submerged in pluvial Lake Alvord. Now, high-temperature springs, steam vents, and mud pots are concentrated in a 50 × 50 m area near the southern edge of the spring area.
