Field tests of a portable MEMS gravimeter [PDF]

, 2017
Gravimeters are used to measure density anomalies under the ground. They are applied in many different fields from volcanology to oil and gas exploration, but present commercial systems are costly and massive.

Apollo 17 Lunar Surface Gravimeter as a Seismometer: Relocating Shallow‐Moonquake Sources and Implications for Source Mechanism

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Among the reported seismic events on the Moon, shallow moonquakes are known for their unique features, such as high‐frequency energy excitation, similarity to intraplate earthquakes, and the largest energy release of all reported moonquakes. Despite these interesting features, a small number of samples (<80 events) and sparse seismic network ...

Resistivity Structure of the Alabama‐Oklahoma Lineament and Mississippi Embayment: Insights Into Crustal Weakness, Heat Flow, and Seismicity of the Region

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract The Alabama–Oklahoma Lineament (AOL) is a major crustal boundary that intersects the Mississippi Embayment (ME) and may influence intraplate deformation in the southern United States. We present the first regional magnetotelluric (MT) resistivity models across the AOL–ME system using EarthScope data and two‐dimensional inversion. All southwest–

A possible paleorift zone in the Central Dharwar Craton of South Indian Shield: Evidence from regional gravity anomalies

Geosystems and Geoenvironment, 2023
A conspicuous zone marked with linear Bouguer gravity anomalies encompassed with overall regional gravity high zone spreads about 5° length and width of about 1 to 1 1/2° in the central part of Dharwar Craton is not entirely relatable to surface ...

Holocene Normal Faulting in the Southern Rocky Mountain Trench; Orogenic Collapse Modulated by Glacial Unloading?

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Southern Rocky Mountain Trench (SRMT) is a conspicuous valley in the eastern Canadian Cordillera. It lies above a sharp change in lithospheric strength and thickness and is occupied by a normal fault thought to have last been active in the Eocene.

Estimation of CO2 Emissions in Fault Systems at a Global Scale

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract Influenced by tectonic, geophysical, and environmental aspects, the release of carbon dioxide (CO2) in fault systems is a fundamental component of Earth's carbon cycle. Appreciating their contribution to natural greenhouse gas flow depends on knowing these emissions.

Supervised Swin Transformer‐Based Predictive Lithological Mapping and Uncertainty Quantification Using Aeromagnetic and Gravity Data

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract Lithological mapping is essential for the exploration of critical minerals supporting energy transition and national defense. Although recent advancements have incorporated multi‐source data sets and leveraged machine learning and deep learning (DL) methods, lithological mapping continues to face significant challenges, such as data imbalance,

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

, 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;

Time‐Varying Gravity Constraints on Groundwater Recharge and Managed Aquifer Strategies in Southern Taiwan

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Understanding groundwater recharge pathways is essential for designing effective managed aquifer strategies, yet in heterogeneous alluvial aquifers, these pathways are often uncertain and difficult to resolve with sparse well networks. We apply gravity as an independent constraint to quantify groundwater storage dynamics and evaluate recharge ...
