Geophysical investigation along parts of the Dent and Augill Faults [PDF]

open access: yes, 1978
The areas covered in the present investigation lie near the towns of Brough and Kirkby Stephen. They include parts of the Dent and Augill Faults, which form the western margins of the Askrigg and Alston Blocks respectively.

A Cloud Screening Preprocessing Framework for GOCI‐II Aerosol Optical Depth: Development and Impact on Retrieval Errors

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 1, 16 January 2026.
Abstract Accurate retrieval of satellite‐derived aerosol optical depth (AOD) is critical for air quality forecasting, especially when AOD is assimilated into models. However, if retrieval errors in the satellite‐derived AOD are not corrected or characterized, they can lead to false analysis increments and ultimately degrade the quality of data ...

Bouguer gravity field of the Tuscan Archipelago (central Italy)

open access: yesJournal of Maps, 2019
In this paper, we present a new Bouguer gravity map of the Northern Tuscan offshore (central Italy), based on original gravity data acquired on the islands of the Tuscan Archipelago.

Gravity data reduction, Bouguer anomaly, and gravity disturbance

open access: yesГеофизический журнал, 2023
Each point on the earth has a gravity and gravity potential value. Surfaces formed by connecting points with equal gravity potential values are called equipotential surfaces or level surfaces.

Magmatic and Tectonic Structures in the Crust Beneath Armenia and Surrounding Regions of Lesser Caucasus Inferred From Body‐Wave Earthquake Tomography

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract The Armenian Highlands, a tectonically active segment of the Arabia‐Eurasia collision zone, exhibit widespread Quaternary volcanism, rapid uplift, and intense seismicity. However, the lithospheric processes driving these phenomena remain poorly understood.

PEMODELAN 3D STRUKTUR BAWAH PERMUKAAN GUNUNGAPI AGUNG PROVINSI BALI MENGGUNAKAN METODE GAYA BERAT

open access: yesJGE, 2020
Under surface structure, 3d modelling of Agung volcano in Bali had been conducted by using gravity methods. This research aims to identify the magma chamber and make a model below the surface of the Great Volcano of Bali Province by using gravity anomaly

Bouguer anomaly map of New Zealand [PDF]

open access: yesNew Zealand Journal of Geology and Geophysics, 1958
Summary The Bouguer map of New Zealand exhibits two major negative gravity anomalies. The Rangitikei-Waiapu Anomaly, which intersects tne axial ranges of the North Island, indicates a crustal downwarp which is not in isostatic equilibrium. This anomaly is closely parallel to the zone of intense seismicity, to the Taupo-White Island volcanic belt, to ...

Lithospheric 3D gravity modelling using upper-mantle density constraints: Towards a characterization of the crustal configuration in the North Patagonian Massif area, Argentina [PDF]

open access: yes, 2017
The North Patagonian Massif is an Argentinean plateau that has an average height of 1200 m and stands from 500 to 700 m above the neighboring areas. During Paleogene, it suffered a sudden uplift of more than 1200 m without noticeable internal deformation;

Evidence of Subduction, Collision, and Extension in Northern Borneo: Constraints From Receiver Functions

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract What happens when subduction stops is a key, but poorly understood, part of the tectonic cycle. Northern Borneo (Sabah) with a complex geological history of multiple episodes of subduction, magmatism, uplift, subsidence, and extension since the Mesozoic, is an ideal location for studying post‐subduction processes.
