“…The Landsat satellites that still provide services are Landsat 7 and Landsat 8. The OLI and TIRS sensors are used by Landsat 8, and ETM + sensors are found on Landsat 7 (Chan et al, 2018;Yanis et al, 2020b). Landsat 7 is an eight-band satellite launched on April 15, 1999, using the ETM + sensor concept.…”

“…The geothermal manifestations, such as crater and hot spring have been developed into tourist site to accelerate the community's economy development (Borović and Marković, 2015;Marwan et al, 2020). Besides the geothermal energy of Geuredong volcano in the center of Aceh (Yanis et al, 2022b), and the Peut Sagoe volcano in the Pidie district have never been explored using geochemical and geophysical methods, so the Research Article energy capacity of the volcano cannot be predicted (Yanis et al, 2020b;Zaini et al, 2022). This is because the volcanoes situate a high topography, so instrument mobility is very challenging.…”

Geothermal energy, as a part of green and renewable energy, has been widely developed in the world to replace the current conventional fossil energy. Peut Sagoe is an active volcano in the northern part of Sumatra. The volcanic mountain has not been completely explored for geothermal and energy reserves study. This is due to the volcano locates in a high topography and surrounded by dense tropical forest, which makes it challenging to deploy geophysical instruments in the area. The Landsat 8 thermal infrared and meteorological data from 2013 – 2020 were used to estimate the energy resources by calculating the radiative heat flux (RHF) and measuring the energy lost annually through the heat discharge rate (HDR). We also used the normalized differential vegetation index (NDVI) for vegetation analysis, and estimation of its emissivity data. The mono-window algorithm was used to calculate the land surface temperature (LST). The Stefan–Boltzmann equation was utilized to analyze thermal infrared data for RHF, and ambient temperature and relative humidity data were acquired from the Indonesian Meteorological Agency (BMKG) database. The results showed that low vegetation values and high LST of 25°C–35°C were found in crater areas, which indicate the underground thermal activities of the mountain. It demonstrates that the maximum RHF values were 55 W/m2 in 2013 and 37 W/m2 in 2020. The HDR data were calculated by applying 15% of the RHF data, and the amounts of energy lost were 132.5 MWe and 64.5 MWe in 2013 and 2015 respectively. It increased to 186.4 MWe in 2017 and 89 MWe in 2020. Based on these predicted results, we conclude that the combination of thermal infrared imagery of Landsat 8 and meteorological data is an effective approach in estimating geothermal energy potential and energy loss of volcanoes situated in remote areas

“…While there are 20 geothermal sources in the northernmost region of Sumatra, Aceh Province, there are no geothermal power plants [10]. Four of the geothermal sources are activestatus, i.e., Jaboi volcano which has an estimated energy capacity of 50 MW [11], PeutSagou volcano with 100 MW [12], [13], geuredong volcano [14], and the largest volcano SeulawahAgam with an energy of 275 MW [15], [16]. Figure 1 shows the topography of SeulawahAgam which is visualized by the Shuttle Radar Topography Mission (SRTM) with a resolution of 30 m/px [17].…”

SeulawahAgam has planned to construct a geothermal power plant with an estimated 275 MW by the government to replace fossil energy. This study used a magnetotelluric (MT) survey to investigate the primary geothermal system, such as heat sources, reservoirs, or faults, which are responsible for regulating the surface manifestation. The regional volcano and fault of the Seulimum segments were traversed by 26 MT stations. The 1D Inversion was conducted toward the overall MT data using the Occam inversion algorithm from IP2Win MT. This Inversion was performed to acquire characteristics of the geothermal system based on resistivity parameters against the depth. The 1D model distribution was combined and converted into pseudo 2D, which could depict the subsurface conditions. Based on the data analysis, the cross-section model revealed that the volcanic sediment layer near the surface had a resistivity of 57–98 Ωm. In the depth of 4–8 km in profile one, and 0.2–2 km, in profile 2, coverage of clay cap rocks was found with impermeable properties, where the resistivity was low (<10 Ωm). Afterward, the reservoir layer was characterized by resistivity ranging from 94 to 188 Ωm located at 1–3 km depth, where this anomaly could be seen across all measuring tracks. Meanwhile, the region beneath the reservoir was estimated to be a heat source with a depth range of 2–5 km, as evidenced by a high resistivity of more than >1000 Ωm. The pseudo-2D results could provide an initial model of SeulawahAgam’s geothermal system.

“…The system has been operated in China [13] and geothermally in Krafla volcano, Iceland [14]. Both of these systems require several integrated methods such as remote sensing [15][16][17], geochemistry [18,19], and geophysics [20,21], which will be a baseline for the exploration and usage plans of sustainable geothermal sources [22].…”

“…Indonesia has significant amount of geothermal reserves amounting to 28,000 MW [24]. Specifically, the province of Aceh, which is located in the northern part of Sumatra, has ±20 geothermal energy sources, with four active volcanoes, namely, Jaboi on the Weh Island [25], Seulawah Agam in Aceh Besar [26,27], Peut Sagoe in Pidie Jaya [15], and Burni Telong in Bener Meriah. The Indonesian government has planned to construct a power plant in Seulawah Agam, with an estimated energy of 230 Mwe [21,28].…”

Magnetotellurics (MT) is an important geophysical method for exploring geothermal systems, with the Earth resistivity obtained from the MT method proving to be useful for the hydrothermal imaging changes of the system. In this research, we applied the MT method to map the geothermal system of the Seulawah Agam volcano in northern Sumatra, a site intended for the construction of a geothermal power plant with an estimated energy of 230 Mwe. Herein, 3D MT measurements were carried out, covering the entire area of the volcano and the various intersecting local faults from the Seulimeum segment in the NW–SE direction. Based on Occam 2D inversion, a conductive anomaly (<10 ohm·m) near the surface was identified in response to specific manifestation areas, including the Heutsz crater on the northern side and the Cempaga crater on the southern side. A further conductive anomaly was also found at a depth of 1 km, which was presumably due to a clay cap layer covering the fluid in the reservoir layer below the surface, where the manifestation areas are formed at various locations (where faults and fractures are found) owing to the fluid in the reservoir rising to the surface. The MT modeling also revealed that the reservoir layer in Seulawah Agam lies at a depth of 2 km with a higher resistivity of 40–150 ohm·m, which is the main target of geothermal energy exploration. At the same time, the heat source zone where magma is located was estimated to lie in two locations, namely, on the northern side centering on the Heutsz crater area and the southern side in the Cempaga crater area. A clear 3D structure obtained via Occam inversion was also used to visualize the hydrothermal flow in the Seulawah Agam volcano that originates from two heat source zones, where one structure that was consistent across all models is the conductive zone that reaches a depth of 5 km in the south in response to the regional faulting of the Seulimeum segment. Based on the MT research, we concluded that the volcano has the geothermal potential to be tapped into power plant energy in the future.
