Mágneses torzulások a magnetotellurikában / Magnetic distortions in magnetotellurics : A klasszikus MT feldolgozási eljárások várható torzulásai mágneses közeg megjelenése esetén, 2D direkt modellezés eredményei extrém nagy mágneses peremeabilitás esetén = Magnetic distortions in magnetotellurics. Predictable distortions in classical processing MT procedures, in presence of a magnetic medium, based on 2D direct modeling results

, 2023
Amint korábbi tanulmányok rámutattak arra, hogy a magnetotellurikus méréseknél az elektromos vezetőképesség mellett változóként megjelenik a mágneses permeabilitás is, amire a meglévő magnetotellurikus feldolgozási eszköztár nincs felkészítve.

Three‐Dimensional Resistivity Structure of Iwo‐Yama Volcano, Kirishima Volcanic Complex, Japan: Relationship to Shallow Seismicity, Surface Uplift, and a Small Phreatic Eruption

Geophysical Research Letters, 2018
Iwo‐yama volcano, part of the Kirishima Volcanic Complex, has recently shown signs of unrest. We conducted a hypocenter relocation of shallow earthquakes and broadband magnetotelluric measurements around Iwo‐yama.

Anisotropic forward modelling of fluid injection and phase angles exceeding 90o in magnetotellurics [PDF]

, 2012
This item is only available electronically.Electrical anisotropy, defined as the directional dependence of electrical conductivity within a medium, causes changes in the electromagnetic signal measured by magnetotellurics (MT) and as such is an important

Combined geophysical (magnetotellurics) and geochemical results for determination of the Lithosphere-Asthenosphere Boundary (LAB) beneath the Nógrád-Gömör Volcanic Field

, 2014
Understanding the fundamental role of LAB is substantial for the investigation of the geodynamic evolution of the Earth. The LAB depths can be estimated by different geophysical methods (seismology, magnetotellurics), however these depths are ...

Long‐Term Peak Geoelectric Field Behavior for Space Weather Hazard Assessment in Alberta, Canada Using Geomagnetic and Magnetotelluric Measurements

Space Weather
To better understand the risks of space weather to electric power transmission networks, magnetometer data and nearby magnetotelluric impedance data at four sites in Alberta, Canada are used to estimate the induced geoelectric field over the last 12–32 ...
