Britain 3D MT Model Reveals Hidden Subsurface Geophysics
New 3D Electrical Map Sheds Light on Britain’s Deep Structure A milestone in terrestrial geophysics arrives with Montiel-Álvarez and colleagues’ first 3D electrical resistivity model of Britain. Built from long-period magnetotelluric (MT) data collected across the island, the model—named BERM-2024—provides a high-resolution view of how electrically conductive and resistive rocks are arranged beneath Britain’s surface.…

New 3D Model Reveals Britain’s Subsurface Geophysical Structures
Unveiling Britain’s Hidden Architecture Magnetotelluric (MT) surveys, which measure natural electric and magnetic field variations at the Earth’s surface, offer a window into the subsurface by mapping electrical resistivity. Changes in resistivity help scientists identify geologic features such as igneous intrusions, sedimentary basins, and variations in crustal composition. A new 3D resistivity model, based on…

New 3D Model Reveals Geophysical Structures Beneath Britain
Unveiling Britain’s Subsurface with 3D Magnetotellurics Researchers have produced the first comprehensive 3D electrical resistivity model of Britain, offering a new view into the country’s hidden geophysical structures. The model, called BERM-2024, is built from long-period magnetotelluric (MT) data that track variations in electric and magnetic fields at Earth’s surface. By interpreting how easily electrical…
