Identifying mountain permafrost degradation by repeating historical electrical resistivity tomography (ERT) measurements [PDF]

The Cryosphere, 2023
Abstract. Ongoing global warming intensifies the degradation of permafrost. Permafrost thawing impacts landform evolution, reduces freshwater resources, enhances the potential of natural hazards and thus has significant socio-economic impacts. Electrical resistivity tomography (ERT) has been widely used to map the ice-containing permafrost by its ...

SHALLOW SUBSURFACE STRUCTURES AND QUATERNARY DEFORMATIONS ON THE EASTERNMOST MATANO FAULT, INDONESIA, REVEALED BY ELECTRICAL RESISTIVITY TOMOGRAPHY

Rudarsko-geološko-naftni Zbornik
In active fault studies, electrical resistivity tomography (ERT) with wide electrode spacing (10 m) and fewer than 60 electrodes is typically utilized. However, this configuration limits the ability of ERT to resolve detailed geological information, such

Lithology Of Geothermal Potential Areas Using The Electrical Resistivity Tomography (ERT) Method

JURNAL GEOCELEBES, 2023
The rock lithology of the potential hydrothermal area has been studied using Electrical Resistivity Tomography (ERT) in Pungguk Pedaro Village, Bingin Kuning District, Lebong Regency. Field data acquisition uses a stretch length of 480 meters with the MAE X612-EM Geoelectric tool that forms a straight line. ERT method, using Res2dinvx64 software.

3D interpretation of helicopter-borne frequency-domain electromagnetic (HEM) data from Ramså Basin and adjacent areas at Andøya, Norway

Earth, Planets and Space, 2020
The Ramså Basin is situated on the strandflat on the northeastern side of Andøya between Ramså and Skarstein. It is the only known Mesozoic sedimentary basin onshore Norway and therefore represents an easily accessible analogue to study the setting and ...
