High-Speed Railways Interference Signal Characteristics and Multiple Remote References Denoising of Magnetotelluric Data in Jizhong Depression, China

Applied Sciences, 2023
In the economically developed Beijing–Tianjin–Hebei region, magnetotelluric data are susceptible to contamination from cultural noise, which can be caused, for example, by urban stray currents, high-speed railways, or high-voltage lines.

Determination of the Lithosphere-Asthenosphere Boundary (LAB) beneath the Nógrád-Gömör Volcanic Field by combined geophysical (magnetotellurics) and geochemical methods [PDF]

, 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 ...

Crustal Structure Across the Okavango Rift, Botswana: The SEISORZ Wide‐Angle Seismic Experiment

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract The Okavango Rift Zone (ORZ) is an incipient continental rift in Botswana at the terminus of the Southwestern Branch of the East African Rift System. The lack of syn‐rift magmatism and tectonic processes overprinting pre‐rift structures provide an opportunity to investigate incipient‐stage rift processes and the role of pre‐existing structures

Deep Sources of Recent Volcanism in Armenia Inferred From Ambient Noise Tomography

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract We perform Rayleigh wave ambient noise tomography to investigate crustal seismic velocity structure and sources of volcanism in Armenia. Armenia, a key part of the tectonically and volcanically active Caucasus‐Anatolia region, is actively being deformed by the ongoing Arabian‐Eurasian continental collision.

Signals and noise in magnetotellurics [PDF]

SEG Technical Program Expanded Abstracts, 1985
Magnetotelluric noise properties were determined as a function of separation using an orthogonal array of stations. The simultaneous recording of high sensitivity biaxial tiltmeters along with the electric and magnetic fields allowed a measurement of the magnetic noise caused by sensor movement within the earth's static field.

Seismological Characterization of Northern Hikurangi Margin Slow Slip Regions Associated With Normal Faults, Seamounts, and Seeps

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract At the northern Hikurangi margin, Aotearoa New Zealand, slow slip events (SSEs) recur every 6–24 months to ∼ ${\sim} $30 km depth. Although shallow SSEs (0–10 km) are well‐studied offshore, the deeper portion (10–30 km) remains poorly understood, limiting insight into SSE initiation.

A review on the magnetotelluric studies over the Central Asian Orogenic Belt—recent developments and future aspects

Frontiers in Earth Science
The Central Asian Orogenic Belt (CAOB) was originated from the subduction, closure, convergence, and post-collisional extension of the Paleo-Asian Ocean located between the North China Craton, Tarim Craton, and the Siberian Craton during the late Permian

Joint inversions of three types of electromagnetic data explicitly constrained by seismic observations: results from the central Okavango Delta, Botswana [PDF]

, 2017
The Okavango Delta of northern Botswana is one of the world's largest inland deltas or megafans. To obtain information on the character of sediments and basement depths, audiomagnetotelluric (AMT), controlled-source audiomagnetotelluric (CSAMT) and ...

Electrical Conductivity of Carbonatite Melts to 20 GPa: Constraints on Partial Melting Atop the 410‐km Discontinuity and in the Lower Mantle Transition Zone

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Deep‐origin carbonatite melts are considered to be the products of partial‐melting of the oceanic crust in the subduction zones. In this study, we conducted electrical conductivity (EC) measurements on two samples, the composition of which resemble the partial‐melting products atop the 410‐km discontinuity and in the lower part of the ...
