Stratigraphic Model of East Biak Based on Magnetotelluric Data

open access: yesJournal of Mathematical and Fundamental Sciences, 2020
Biak Island is thought to have originated from the Australian Continental passive margin in the Mesozoic. This passive margin underwent tectonic collision to form the bedrock of Biak Island during the Paleogene.

A Study on Magnetotelluric Characteristics of Magmatic Geothermal Systems

open access: yesEnergies, 2022
The Magnetotelluric (MT) method is a widely used and effective method of exploring geothermal resources because it can reveal geological information at a great depth and is cost effective. In order to further improve the reliability and rationality of MT

Three-Dimensional Magnetotelluric Characterization of the Travale Geothermal Field (Italy)

open access: yesRemote Sensing, 2022
The geoelectrical features of the Travale geothermal field (Italy), one of the most productive geothermal fields in the world, have been investigated by means of three-dimensional (3D) magnetotelluric (MT) data inversion.

Efficient two-dimensional magnetotellurics modelling using implicitly restarted Lanczos method [PDF]

open access: yes, 2011
This paper presents an efficient algorithm, FDA2DMT (Free Decay Analysis for 2D Magnetotellurics (MT)), based on eigenmode approach to solve the relevant partial differential equation, for forward computation of two-dimensional (2D) responses.

New Insights into Crust and upper Mantle Structure in Guangdong Province, China and Its Geothermal Implications

open access: yesEnergies, 2021
Southeast Asia contains significant natural geothermal resources. However, the mechanism for generating geothermal anomalies by the crust–mantle structure still needs to define. In this study, we focused on Guangdong Province, China.

The electric field in northern England and southern Scotland: implications for geomagnetically induced currents. [PDF]

open access: yes, 2006
Magnetotelluric (MT) data, in the form of MT tensors, are used to estimate directly the size and spatial distribution of the electric field in northern England and southern Scotland with the aim of predicting the flow of geomagnetically induced currents ...

Deep Electrical Structure of Taiwan as Inferred From Magnetotelluric Observations

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 1998
Not until magnetotellurics (MT) were conducted, was very much known about the deep electrical structures beneath Taiwan. Finally, the first MT was used as part of an integrated project to map 3-D structures; subsequently, nineteen MT soundings, uniformly
