In this paper, we develop a new method of three-dimensional (3-D) inversion of multi-transmitter electromagnetic data. We apply the spectral Lanczos decomposition method (SLDM) in the framework of the localized quasi-linear inversion introduced by Zhdanov and Tartaras (2002 Geophys. 1. Int. 148 506-19). The SLDM makes it possible to find the regularized solution of the ill-posed inverse problem...

Inversion is a fundamental step in magnetotelluric (MT) data routine analysis to retrieve subsurface geoelectrical model that can be used inform geological interpretations. To reduce the effect of non-uniqueness and local minimum trapping problems improve calculation speeds, data-driven mathematical method with deep neural network was developed estimate resistivity. In this study, learning (DL)...

<p class="TesisTextOneHalfSpace"><em>Indonesia is one of the country having a lot geothermal fields potentially used as source energy. For example, Java island noted to have almost 57 fields. One those which rarely studied Guci field. Hence, there was conducted research investigate subsurface image and system in field based on resistivity data. </em><em>The carried out u...

A resistivity and time-domain induced polarization (IP) survey was conducted at a landfill site under restoration at Härlöv in Southern Sweden. The covering of the landfill had begun some years ago, without keeping precise records of the work done, as is usual in such procedures. The survey was conducted in two steps, on two adjacent areas. First, a number of geoelectrical sections were made on...

Multifractal fluctuations in the time dynamics of geoelectrical data, recorded in a seismic area of southern Italy, have been revealed using the Multifractal Detrended Fluctuation Analysis (MF-DFA), which allows to detect multifractality in nonstationary signals. Our findings show that the geoelectrical time series, recorded in the seismic area of southern Apennine Chain (Italy), is multifracta...

The interpretation of the segment deep three-dimensional Crimean region geoelectrical model within Saki and Yevpatoria profiles, built on basis Earth's low-frequency electromagnetic field experimental observations, was obtained in 2012 by INSTITUTE OF GEOPHYSICS named after S.I.Subbotin. main result analysis is identification vertical horizontal alternation high low resistivity, both earth's cr...

After a large landslide event in Sibratsgfäll/Austria several exploration methods were evaluated on their applicability to investigate and monitor landslide areas. The resulting optimised strategy consists of the combined application of airborne electromagnetics, ground geoelectrical measurements and geoelectrical monitoring combined with hydrological and geological mapping and geotechnical mod...

Abstract The Covid-19 pandemic has made one of the tourists in East Lampung regency inactive, namely “Gua Pandan.” Due to its unique location geologically, efforts must be revive area. One approaches is applying an indirect method, geophysical method. them geoelectrical profiling Six lines are spread study area with a length 70-105 m. target cave filled air because it suitable as tourist spot. ...
