Conductive structures around Las Cañadas caldera, Tenerife (Canary Islands, Spain) : a structural control [PDF]
External eastern areas of the Las Cañadas caldera (LCC) of Tenerife (Canary Islands, Spain) have been investigated using the audiomagnetotelluric (AMT) method with the aim to characterize the physical rock properties at shallow depth and the thickness of

The Gannon Storm's Impact on Electric and Magnetic Fields in Italy: A Regional Perspective
Abstract The intense May 2024 geomagnetic storm provided an opportunity to conduct the first analysis of geoelectric hazards in Italy. Data from three geomagnetic observatories and a magnetotelluric station were analyzed to examine the spatiotemporal evolution of storm‐induced variations.

Stratigraphic Model of East Biak Based on Magnetotelluric Data
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.

Abstract Geomagnetically induced currents (GICs) are telluric currents driven by space weather that can adversely impact high voltage transformers in electricity supply networks. It is often difficult to obtain transformer GIC data so ground based magnetometer data may be used to estimate the transformer GIC via complex modeling of both network and ...

Beyond magnetotelluric decomposition: Induction, current channeling, and magnetotelluric phases over 90° [PDF]
This paper presents a method to examine strong current channeling affecting the magnetotelluric (MT) impedances, going beyond existing tensor decomposition schemes. The method allows recognition of elongated conductors in the crust and is also useful for a qualitative recognition of general three‐dimensional (3‐D) high‐conductivity anomalies.

Abstract The Newer Volcanic Province (NVP) in southeastern Australia is a classic example of continental intraplate volcanism located far from a plate boundary, yet the configuration of its magma plumbing system remains unclear. Using three‐dimensional (3D) magnetotelluric (MT) inversion, we imaged a vertically continuous, trans‐lithospheric conductive

Continental rifting is initiated by a dynamic interplay between tectonic stretching and mantle upwelling. Decompression melting assists continental breakup through lithospheric weakening and enforces upflow of melt to the Earth's surface.

Audiomagnetotelluric investigation of seawater intrusion using 2-D inversion of invariant impedances [PDF]
An audio-magnetotelluric survey was conducted to estimate the extension of the seawater intrusion in a coastal aquifer, in Ensenada, Baja California, México. The survey consisted of 134 closely spaced sites along three profiles 5 to 6 km long.
