“…The injected current spreads under the surface, from which potential difference values measured by M and N potential electrodes are obtained. The field data acquisition process uses Schlumberger configuration due to its efficiency and error minimal [11]. The working principle of this configuration is shown by Figure 1, which shows that distance between MN potential electrodes is closer, while the distance of current electrodes is changed gradually according to the predetermined lane length.…”

Drought is one of the problems faced by the people of Lembor Village, Lamongan Regency, this problem will be slightly resolved if the area has reserves of groundwater sources. Therefore, this study aims to determine the existence of potential groundwater sources around Lembor Village. The method used is the geoelectrical resistivity method schlumberger configuration. Data acquisition was carried out for 10 measuring points of Vertical Electrical Sounding (VES) with a track length of 310 meters, and a distance between electrodes of 10 meters. The measurement results are then correlated between VES points to produce a 2-dimensional cross-section. The results showed that the measured resistivity value was between 0.03 Ωm to 81.1 Ωm. The structure of the subsurface layer of the study area is dominated by clay and limestone. The indications for the presence of groundwater are found at a depth between 25 to 35 meters at a track distance of 35 to 45 meters, a track distance of 170 to 180 meters, and a track distance of 270 to 280 meters with resistivity values between 0.03 Ωm to 0.32 Ωm. The indications of the presence of groundwater sources need to be investigated in a wider area, to determine the distribution and direction of groundwater flow.

“…Three case studies which we have been discussed showed that resistivity method was approriate for mitigating hydrometeorological disaster. For further analysis, we comparing withresistivity data from landslide disaster area in Pulung Subdistrict, Ponorogo in 2017 [19]. From 12 resistivity measuring points in the area, it was identified rock with resistivity ranging(1.4-67.5)Ωm which were interpreted as clay, tuff lapili, volcanic breccia, and andesite lava.…”

The research has been carried out about natural disasters (landslides, ground motion, drought) using geophysical methods. This research was conducted in several places, in East Java, i.e. land slides and ground motion occurred in Malang and Blitar areas and drought occurred in theTulungagung and Malang areas. This research uses resistivity and self-potential. The active method is resistivity, which means that an electric current is injected into the earth, after which the resulting potential difference is recorded, then processed. Self-potential and geomagnetic methods, are passive methods. In the self-potential method, the potential difference that occurs between two points, which have a certain distance, is recorded (the middle between those two points becomes a point measurement). The data of several points of measurement, that have been made within a certain distance, then is processed for determining underground river tracing. The equipment used is the OYO Mac Ohm resistivity meter. The results obtained are, an artesian well in the Tulungagung area, at a depth of 108 m, an indication of new faults in the Blitar area, and ground motion cracks in the Malang area.

“…The resistivity cross-section can be used to identify rock layers and the direction of the subsurface structure [18]. Many additional geoelectrical resistivity studies have been conducted to prevent geological disasters, such as identifying structures (faults) and subterranean lithology that can trigger geological disasters [19][20][21].…”

Microtremor and geoelectrical resistivity surveys have been conducted in areas where the April 10, 2021, earthquake of 6.1 Mw caused the most damage. Wirotaman Village, Malang Regency, was one of the regions with the most extensive damage. This study aims to investigate the seismic vulnerability and subsurface conditions that result in severe damage at the research location. This study's Horizontal to Vertical Spectral Ratio Analysis (HVSR) curve was derived from the recorded microtremor signal in the frequency domain. The frequency parameter and amplification factor obtained from the curve are used to determine the seismic vulnerability index. In addition, a geoelectrical resistivity study with a dipole-dipole configuration was conducted at the site with the most extensive damage. The results of this study show the correlation between the results of the HVSR curve analysis and geoelectrical resistivity in determining the seismic vulnerability of an area. The results indicated that the high seismic vulnerability index value ranged from Kg= 12.0 to 18.0, with the most severe damage concentrated in the Southwest at SA 05 and SA 06. Based on the results of the geoelectrical survey, information was obtained that several points of damage to buildings at SA 05 (red circle) were on the same line, where this condition was associated with the possibility of new faults at that location. This microtremor and geoelectric resistivity investigation reveals thick sedimentary deposits with a high seismic vulnerability index and low resistivity. This study's findings can be utilized as a guide for micro zonation studies in research areas. This research contributes to the surrounding community in the form of disaster mitigation, where construction must avoid local fault positions that have been found to reduce the level of damage when natural geological disasters occur.
