Characterizing Stalagmites’ Eigenfrequencies by Combining In Situ Vibration Measurements and Finite Element Modeling Based on 3D Scans

open access: yesGeosciences, 2020
Broken or deformed speleothems have been used as indicators of paleo-earthquakes since the 1990s; however, a causal link is difficult to prove except for some thin speleothems.

Identification of natural and technogenic decompacted zones in the worked-out massif based on high-precision gravimetric observations

open access: yesВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2023
The paper presents the results of gravimetric studies at the potassium salt deposit in order to obtain information on the development of negative engineering-geological processes in the rock mass caused by subsoil development. A methodology was developed

Joint inversion of muon tomography and gravimetry - a resolving kernel approach [PDF]

open access: yes, 2014
Both muon tomography and gravimetry are geophysical methods that provide information on the density structure of the Earth's subsurface. Muon tomography measures the natural flux of cosmic muons and its attenuation produced by the screening effect of the

Gravimetry through non-linear optomechanics [PDF]

open access: yes, 2018
We propose a new method for measurements of gravitational acceleration using a quantum optomechanical system. As a proof-of-concept, we investigate the fundamental sensitivity for a cavity optomechanical system for gravitational accelerometry with a ...

Microelectromechanical system gravimeters as a new tool for gravity imaging [PDF]

open access: yes, 2018
A microelectromechanical system (MEMS) gravimeter has been manufactured with a sensitivity of 40 ppb in an integration time of 1 s. This sensor has been used to measure the Earth tides: the elastic deformation of the globe due to tidal forces.
