A research using remote sensing have been done on Kawah Wurung-Ijen. This research was conducted to analyze the distribution of land surface temperature and to identify the geothermal manifestations. The land surface temperature was obtained by using emissivity method of calculating the Normalized Difference Vegetation Index (NDVI). Remote sensing data was used more secund data from Landsat 8. The result shows that the research area has the land surface temperature distribution in ranges 10°C to 50°C. The interpretation shows any anomalous area in ranges 31°C to 50°C that indicated as geothermal potential area. The anomalous are associated with volcanic areas. In the West is associated with Mt. Genteng, in the North is associated with Mt. Gending Waluh. In addition, there is also an anomaly in the East precisely around kolovium of Mt. Kukusan.

Have been research geothermal of Arjuno Welirang area of East Java with geoelectric resitivity tomography. Geoelectric tomography was performed by VES (Vertical Electrical Sonding) and Mapping. Acquisition of data totaled 7 points of VES and 4 tracks Mapping was located surrounding the hot springs.Results of geoelectric resistivity modeling showed the resistivity of rock layers the carrier fluid (water) heat <10 Ohm.meter, while a layer of carrier fluid (water) was worth 10-100 Ohm.meter. The hot fluid coming from the direction of CR4 and CR3 are located in the south from the hot springs with a depth of 24.7 meters from the ground CR 3 (see Figure 5) which alleged a layer of sand, with layers of lava rock in the form of heat source at depth 34 meters. Mapping the results of modeling that consists of 4 tracks show around hot springs artifacts crack / crack is suspected as a medium to hot water flow out of the ground surface, precisely located at CANGAR_LINE1.

Study of the focal mechanisms of A-Type Volcanic earthquake (VA) Semeru has been done to know the volcanic activity in more detail, until the information about the magma migration process. The study began with the selection of seismic events that has a clear appearance, continued with the conversion value in the instrument readings and the amplitude correction which includes the correction of propagation effect and local effect. Hypocenter distribution showed that the epicenter was dominant in the northwest direction, relative to the central volcano, with a depth between 1-13 km. Interpretation of the hypocenter distribution, supported by past research as well as geological information around, gave initial estimates that there was a column of magma flow that leads from the northwest to the center of the crater. VA study of earthquake focal mechanism illustrate that the dominant type of normal fault occurs at the peak of eruption, and would change to reverse fault after the activity dropped to normal. From the research, VA earthquake in G. Semeru could be classified into two types: deep VA (VAD) with a depth range of more than 6 km and the shallow VA (VAS), with a depth of 1-6 km.

The research has been done in Cangar area of complex Mt.Arjuno-Welirang, East Java. This research using magnetotelluric method. The purpose of this research is to identify the geothermal system of research area based on its resistivity value. Acquisition of magnetotelluric data done in 11 point with spaces 70 meters up to 150 meters. Magnetotelluric measurement points is divided into 5 profile. Based on the result of data processing given range resisitivity value in research area between 4 W.m up to 2000 W.m. The result of modeling geothermal system in Cangar indicated of caprock (≤21 W.m), reservoir (21 W.m – 167 W.m) and a heat source (≥167 W.m). Geothermal Cangar is controlled by Cangar fault.

The image of subsurface with a migration method keeps on developing to get an image result which the closest in real condition. The conditions in subsurface are very complex and variables it couses the process of wave propagation which can not be judged as the same in every layers. so it is needed an anisotropy pharameter analysiz (η) in seismic data migration process. The research will compare two kinds of migrations those are Kirchhoff migration and finite difference anisotropy. It is done because not all datas are processed by anisotropy, even with isotropi it will get good result. The result of kirchoff migration has not so good quality (low resolution) on the first layer reflector.but on the second and third layer reflector have good result (high resolution). I estimate that in the first layer reflector there is anistropi influence, because the ratio effect between far offset and the depth is hight. The analysis result get η ansotropi pharameter result as 0,25 and put into migration process. On the second migration process is finite difference anisotropy appears on the first layer reflector and shows high resolution and suitable with the real layer model.

Sakenan Temple is one of the most sacred and historic temples in Bali. Located on Serangan Island. In addition, Sakenan Temple is an area located in the tectonic pile zone that causes earthquakes. The purpose of this study was to examine possible land movement near Sakenan Temple in Bali in attempts to lessen local calamities. The sentinel 1-A picture data from August 2022–2024 is used in this research methodology. processed on SNAP software with the DinSAR approach to extract variables related to land movement. According to the findings, there was land movement in August 2022–2023 from -0.109 to 0.145 cm/year and in August 2023–2024 from -0.245 to 0.207 cm/year. Negative numbers indicate land subsidence, while positive values indicate uplift. There is an increase in land movement, with an average of -0.158 cm/year for land subsidence and 0.176 cm/year for uplift between August 2022 and August 2023 and -109 cm/year between August 2023 and August 2024. The value of land movement increased, increasing by -0.178 cm/year. The average is -0.156.

Mount Semeru is an active volcano located on the island of Java. On December 4, 2021, Mount Semeru erupted again, resulting in damage and loss of life. Sentinel-2 satellite imagery was utilized for mapping vegetation areas, while Sentinel-3 was employed for assessing surface temperatures. The NDVI distribution related to the Semeru volcano eruption indicates that the extent of cloud cover, water, and open vegetation was consistent before, during, and after the eruption. Before the eruption, areas of very low vegetation were more prevalent than during and after. In contrast, areas of low vegetation were more common following the eruption compared to the eruption period and before it. Medium vegetation remained dominant after the eruption in comparison to the periods before and during it. In contrast, high vegetation was most abundant during the eruption and was at its lowest before the eruption occurred. The land surface temperature recorded before the eruption ranged from a minimum of 11.8 °C to a maximum of 30.12 °C. During the eruption, temperatures peaked at 42.4 °C and dropped to a low of 14.0 °C. Following the eruption, the maximum temperature recorded was 40.8 °C, with a minimum of 11.6 °C. The presence of lava flow during and after the eruption is indicated by the red circle on the land surface temperature map, and when compared to the NDVI map, the black circle shows areas where vegetation was absent due to the lava flow observed on the land surface temperature map
