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.

Magnetotelluric Variations in Nigeria

Journal of geomagnetism and geoelectricity, 1972
A study of the daily variations of earth-current and geomagnetic fields at stations lying north and south of the magnetic equator in Nigeria is presented. The experimental results show that, during the period of measurements, the east-west component of earth-current variation is predominant for stations lying within about 2° from the magnetic equator ...

Modeling overthrust structures for hydrocarbon exploration by 3D magnetotellurics

The seismic reflection method is widely used in hydrocarbon exploration due to its ability to provide detailed imaging of sedimentary layers. However, in overthrust terrains where high velocity rocks (e.g., volcanic cover) overlie low velocity sediments,

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

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 ...
