Post‐Eruptive Deformation and Faulting Caused by Dike Channel Retraction, Material Drain‐Back and Contraction of the 2021 Tajogaite Craters (La Palma)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Young scoria cones fed by dike channels or conduits may undergo rapid and substantial post‐eruptive morphological modification; however, the structural controls and mechanisms governing topographic degradation remain poorly constrained. This knowledge gap limits our ability to reliably interpret topography, faults, deposits and the evolution ...

A high-resolution aeromagnetic survey over the Cape Roberts Rift Basin: correlations with seismic reflection and magnetic susceptibility log data. Extended abstract [PDF]

, 2007
A high resolution aeromagnetic survey (altitude 125 m asl, spacing 500 m , area 800 km2) was carried out in 1994 offshore of Cape Roberts by the GITARA (German ITalian Aeromagnetic Research in Antarctica) Group.

Enhancing the total-field magnetic anomaly using the normalized source strength

Open Geosciences
Enhancement methods of aeromagnetic data are widely used in mapping geological features. Many methods based on field gradients have been introduced to outline the source edges. However, the disadvantage of these methods is that they require the reduction

Processed line aeromagnetic data over Coats Land, including the region of three tributaries of Slessor Glacier, East Antarctica (2001/02 season)

, 2020
During the austral summer of 2001/02 five thousand line kilometres of airborne radio echo sounding and aeromagnetic data were collected in the region of three tributaries of Slessor Glacier, East Antarctica, which drains into the Filchner Ice Shelf.

Quantitative interpretation of aeromagnetic data [PDF]

, 2017
The present work is intended as a contribution to the setting up of a framework for the interpretation of total intensity aeromagnetic data. Although instrumentation for this purpose is in good order, little has been published related to the ...

Aeromagnetic Survey

, 2018
An aeromagnetic survey (AMS) is an air-borne geophysical survey performed using a magnetometer aboard or towed behind an aircraft. A magnetometer is an instrument used to measure the magnetic field.

Aeromagnetic survey in south-eastern Greenland: project Aeromag 2013

, 2014
Aeromagnetic surveys are nowadays used at a wide range of scales and purposes. In frontier and under-explored areas, where data are otherwise sparse or non-existent, aeromagnetic acquisition remains the cheapest and easiest way to obtain or refine a ...
