On the use of low-frequency passive seismic as a direct hydrocarbon indicator: A case study at Banyubang oil field, Indonesia

Open Geosciences
Low-frequency passive seismic (LFPS), discussed in recent years, has emphasized a strong correlation between the spectral properties and the presence of hydrocarbon reservoirs. While the theoretical background supporting this phenomenon is still debated,

Pickin' up good vibrations: a systematic review of footfall detection and analysis in the realm of wildlife surveying

Wildlife Biology, EarlyView.
Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

Numerical Method for Computing Seismic Slip-Line Fields and Earth Pressure Coefficients in Cohesionless Backfills [PDF]

Lithosphere
This study introduced a novel numerical method for calculating seismic slip-line fields and earth pressure coefficients in cohesionless backfills with an inclined and rough retaining wall. By integrating the triangular slice method with the pseudo-static

The Lunar Surface Gravimeter as a Lunar Seismograph [PDF]

, 2008
Introduction: The primary objective for the Lunar Surface Gravimeter (LSG) on Apollo 17 was to search for gravitational waves, but it failed in detecting them [1]. When the instrument was deployed on the Moon, the sensor beam could not be balanced in the

Nonlinear dispersion relation in anharmonic periodic mass-spring and mass-in-mass systems

, 2018
The study of wave propagation in chains of anharmonic periodic systems is of fundamental importance to understand the response of dynamical absorbers of vibrations and acoustic metamaterials working in nonlinear regime.

Statistical analysis of daily seismic event rate as a precursor to volcanic eruptions [PDF]

, 2003
We analyse time series of daily seismic event rate for the Kilauea, Hawaii, volcano between 1959 and 2000. Individual eruptions are not always preceded by an increase in event rate, and many increases in event rate do not lead to eruption.
